Apologies for revisiting this oft-discussed subject. nVidia no longer support their 3D Vision system, and appear to have stopped manufacturing it. Does anyone have suggestions for an alternative? Not all of our scientists use it, but those who find it valuable would be sad to lose it. To clarify, I'm seeking a desktop solution as we don't have the space for 3D projectors. If there is nothing else out there, I may have to start searching eBay for second hand IR emitters.

The VG278HR (ships with one pair of
shutter glasses) with build in emitter
can be used under windows and linux with
a cheap nvidia quadro card (the ones
without a 3-pin stereo connector).
With the VG278HE under windows and a
cheap nvidia quadro, you will need the
nvidia emitter that uses a usb port for
driving the emitter. To operate the
VG278HE under linux requires a truely
expensive quadro card (k4000 and
upwards) with an optional (!) 3-pin
connector or, purchase an old
refurbished quadro card with 3-pin.

Re: [ccp4bb] Stereo monitors for use with Pymol and Coot
Dear everybody, to my recent experience not everything is good in the stereo world. Since I see that others don't have these problems (and I am happy/sad to see that the same exact combinations work without problems) I would just like to add my experience. For the past 4 months I have been struggling to configure a stereo setup for viewing structures in Pymol. I got the VG278HR and PNY Quadro K600 connected over the original DVI-D cable. Since then I was unable to get anything in stereo on Linux (tried Ubuntu, OpenSUSE, Fedora). Unfortunately I get a blank/black screen whenever I use the stereo option in xorg.conf. Also tried changing the motherboard and CPU but got the same result. In Windows the demo stuff from Nvidia works just fine but again I have problems with Pymol. So far the only way to see anything connected to molecular structures in Windows was via DVI-to-HDMI cable but due to HDMI restrictions the quality isn't as good as it would be over DVI-D. If I use DVI-D that was shipped with the monitor the quadro card is detected in Pymol but the monitor doesn't switch to stereo. I have been in contact with the company that makes Quadro cards (PNY) but they were unable to help me. I also contacted some very kind users of CCP4BB and they kindly answered a bunch of question regarding specific setup options. Thanks again! Still there was no success so far. I am slowly giving up on the stereo so if anybody has any ideas/thoughts what could be wrong/done I would greatly appreciate any insight.

Hi Matic, I'm using a Quadro 600 on an Asus VG278HR screen on RHEL 6.3. All is golden. I created xorg.conf (below) by running nvidia-xconfig after installation of the Nvidia driver. (Recent Nvidia drivers are buggy and you'll have to wear your stereo glasses upside down from time to time because the stereo pairs are flipped, but I guess you'd be happy to get to that point.) After creation of the xorg.conf file, I added two options Option Stereo 10 and Option Composite Disable in sections Screen and Extensions, respectively. Hope that helps.

I beg to differ on this: Also, passive screens have a pol-filter in place, the fine lines of which you will observe on a white background, the more disturbing the closer the viewing distance to the screen is. So, for general office applications (writing text), the screens are less useful. Our LG D2342P has no issue with office work. I never noticed any thin lines on the screen. In fact I think its 2D display is excellent. I wonder if the issue you have is related to the screen size: the pixels of 27 in screens are bigger than our 22 in screens.

So, for general office applications (writing text), the screens are less useful. This is not to big a problem for viewing full screen pictures, games and movies (increased distance to the screen...). Moreover, with passive monitors, as the stereo effect increases with the screen size, the picture looks more pixeled compared to active stereo screens. I personally own a AOC d2769Vh and for 3D movies it is great, for coot not that useful if you plan longer sessions. At work, we operate an ASUS VG278HR (active stereo and build in emitter for glasses). Many hardware testers consider this screen the best one available on the market. If you mainly need it for coot, I recommend to change your priorities and buy an active stereo screen such as Asus VG248QE or Asus VG278HR. You do not need an expensive quadro card (600 will do fine) as the VG278HR has build-in emitter for operation with cheap nvidia glasses. It pays off in the long run to invest a few more dollars as you (I assume) will spend a lot of time in front of the this device (so buy the best as you only have one pair of eyes). - J. - Am 05.03.14 23:46, schrieb Shaun Lott: A rather US-centric question on passive 3D monitors...

Re: [ccp4bb] Stereo monitors for use with Pymol and Coot
Every now and then I pipe on this as well. We have Zalman monitors here - I bought them about 4 years ago - when you could not buy them any more in the states. I just bought them on Ebay - they came new in the box directly from China. The person did fed-ex shipping - did not cost any extra, and at the time it was a very cheap way to get these models that were not available in the US. I don’t know if they still sell this way or not - but for me it worked great. The monitors still work, and I agree with Zhijie, the 2D applications look perfect on them. Maybe it’s because I was so used to old, dim, CRT displays. In any event - they are great monitors for normal work, and it’s nice on occasion to use 3D with them. The 3D is OK - not perfect - but I don’t think any are as good as old CRT displays. The 3D does show what you need. What I really do find with modeling (myself included) is the following: I came from a situation where I used 3D exclusively (SGI’s, CRT’s, blah blah blah). Going to the newer, brighter, faster LCD displays means that 3D isn’t as important to me anymore, and I find that I typically use 2D almost exclusively. Occasionally I do 3D, and when I do, the Zalman is fine for that. Hope that helps Dave On Mar 6, 2014, at 7:50 AM, Zhijie Li zhijie...@utoronto.ca wrote: I beg to differ on this: Also, passive screens have a pol-filter in place, the fine lines of which you will observe on a white background, the more disturbing the closer the viewing distance to the screen is.

Thanks to everyone who responded, on and off the list. I thought I'd post a quick summary. To clarify my question slightly (if belatedly) I'm specifically looking for a passive 3D solution to plug into my MacBook Pro whilst on sabbatical in the USA. I'll be using it for a mixture of 2D and 3D viewing, not for many hours of dedicated hand building of my 3.5A maps. Well, I hope not! ;) The LG D2343PB-BN gets honourably mentioned, and is available in several places: http://www.adorama.com/LOCD2343PBBN.html $273.50 including shipping http://www.bhphotovideo.com/c/product/1002116-REG/lg_electronics_d2343pb_bn_23_mon_led_lcd.html $273.50 + shipping Another candidate is this from AOC: http://www.amazon.com/AOC-E2352PHZ-23-Widescreen-Flicker/dp/B005LORQGG $250 including shipping The Asus VG27AH also got good reports, but is listed as either 'out of stock' or 'unavailable'. However, its kid brother, the VG23AH is available: http://www.pinnaclemicro.com/computer/dsku.php?g=VG23AHm=ASUS $251 including shipping (you need to enter the promo code SAS10 to get $10 off!) This monitor got a poor review on cnet (http://reviews.cnet.com/lcd-monitors/asus-vg23ah/4505-3174_7-35306085.html) but much better and more thoughtful reviews elsewhere (http://3dvision-blog.com/7861-review-of-the-23-inch-asus-vg23ah-passive-3d-ips-display) so I'm going to go with the Asus for the following very scientific reasons: 1) It's $20 cheaper than the LG 2) The colours felt a bit washed out on the only AOC monitor I've used previously 3) It has built in speakers and I don't have any on my desk My feeling is that these will all perform in a very similar fashion - I'll report back once I've plugged it in! cheers Shaun

[ccp4bb] stereo emitter
Colleagues, I was happily using my NuVision 60GX emitter with Quadro FX1400 graphics card for number of years on CRT and recently something went bad and image will flip regularly sending front to back and vice versa. First I thought the card went bad but after installing new one nothing changed. I'm suspecting the emitter now and wondering if now there are solutions better than those emitters. Hopefully it is not too off topic. Thanks in advance for suggestions.

Re: [ccp4bb] stereo emitter
Did your OS/nvidia driver get upgraded? There's a bug in all of the modern nvidia drivers that cause this on the quadro 1300/1400 series. It works fine with the older nvidia drivers, e.g. 173.14.31 (note the legacy 9x.xx.xx drivers have the same problem). We're still able to use that version of the nvidia driver with centos/rhel 6.2. If you update past that version with 6, make sure not to update any of the xorg packages. The newer xorg packages have a new ABI which will only work with newer nvidia drivers, which will then cause the stereo flipping bug.

Re: [ccp4bb] Stereo projectors
Hi Marie,
Do you have special reasons to go with an active system? What programs
do you intend to use for 3d projections?
Since about three years we use a passive system (most likely not
up-to-date anymore) consisting of 2 full-HD projectors (Epson
EB-G5450WU) wall-mounted on top of each other, each having circular
polarized filters in front of the lens (I guess this was
custon-fabricated, but I'm sure commercial solutions exist). We use a
special wall-mounted screen which retains polarization and lots of
passive glasses (light and cheap) with circular polarizing filters
(film). The setup is placed in a lecture hall for about 100 persons, 3d
perception is good from almost all distances and viewing angles, no
significant ghost images (I think the circular polarizing does the trick).
The projectors are connected via HDMI to a dual-port graphics card (low
end NVIDIA QUADRO). The two ports deliver a cloned image, the NVIDIA
graphics driver (Windows 7) converts (splits) hardware stereo signals
('quad-buffered stereo') to the two video ports. 3D vision is then
possible for all applications that use 'quad-buffered'/hardware stereo.
It's not directly available in PowerPoint, though! If you want to show
3D movies/images you need an external player (e.g. Stereoscopic Player)
which supports hardware stereo.
One of the drawbacks: the projectors need to be aligned quite accurately
to each other (screen size, focus, image position). Not so conveinient
for manual adjustment of wall-mounted projectors. I'm happy there are no
frequent earth quakes where we live... ;-)
Hope this helps... sorry, if this is a really 'old-fashioned'. I havn't
looked into recent solutions that might exist by now.
Christoph
Hello, Our Department is looking at purchasing a system to project in
stereo for perhaps 50 people in the audience. The current plan is to
go with an active system, although maintaining the glasses will
likely be a problem. If you have insight into currently available
systems that you are either happy with or disappointed in, could you
please send me your advice? Thank you, Marie (Department of
Biological Sciences, University of Calgary)

Re: [ccp4bb] Stereo monitor
I second everything Jeroen said except the need for a €450 graphics card. We have a Quadro 600, which was only £105 or something like that. The slightly cheaper Quadro 400 would have worked as well. There are now successors to these cards. Unless something has changed in their specification, they should work with the monitor with built-in emitter. Others can comment on that. Best regards.

Re: [ccp4bb] Stereo monitor
The quadro 600 or k600 works fine, been using it for more than a year with that Asus with the built in emitter. In fact the absolute oldest and cheapest option which works is the quadro 370, but you'll want the 600 at least. On Thu, Nov 21, 2013 at 9:19 AM, mesters mest...@biochem.uni-luebeck.dewrote: Hi Andreas, the older quadro 600 (with 96 CUDA cores) features a dual Link DVI-I (do not know why they did not call it DVI-D) but if I look at the specs, NVIDIA tries to suggest (?) the k600 features a DVI-I only. No mentioning it is dual-link. It would not make sense being single-link in the first place but make sure before you buy the new k600 (with 196 CUDA cores) it is really a dual-link DVI-I *i.e.* DVI-D. Some vendors state for the k600, 1x DisplayPort, 1x *Dual Link DVI-I* (Software)... Do not know what software exactly means at this point because I have never seen that before. For the more expensive cards (2000 and up) NVIDIA state they have a DVI-D and a DVI-I. Probably they are trying to confuse us to make us buy the more expensive models.. - J. -
Re: [ccp4bb] Stereo monitor
Hi David, We have had success with the ASUS VG248QE connected with DisplayPort, on an HP Z620 running RHEL 6.4. We like to have dual stereo displays on Linux, and Nvidia is discontinuing many of the cheaper multi-DVI-port cards. We had no success trying to take two Acer DVI monitors and connect them to DP on a Quadro 4000 (not K4000) using various DP/DVI adapters. So we decided we had to switch entirely to native DP connections and chose the VG248QE.No built in emitter on this monitor, however. So I think if you want to use this on Linux, you will need the K4000 or higher. We bought a K5000 to test it with, assuming we could fall back to the K5000's dual DVI ports and our old DVI monitors if DP didn't work. But since we got DP to work, we will probably go with the K4000 for our next batch of Linux workstations, since it appears to be the minimum card that works on Linux with the 3-pin emitter, and also provides two DP connectors. We had problems getting the correct stereo 3-pin bracket adapter for these cards; our reseller initially sent us the wrong one that is apparently for older Nvidia cards (very nice of them to change the plug periodically!) but we were able to get the correct one by talking directly to HP. The card will drive the monitor at 144 Hz when stereo is disabled in the X server config file, but it drops to 120 Hz in stereo mode, which I assume is probably the maximum shutter speed on the 3D Vision Pro glasses.

[ccp4bb] stereo monitors/MAC
Hi, Having now had a chance (finally) to play with the Asus VG27A, I can say that (a) it works really well in stereo with both Coot and PyMol and (b) it is easier and nicer to use than the Zalmans. Though the technology is essentially the same (halving the vertical resolution), they have done two things better than the Zalmans: 1) - they don't just eliminate Pixels in the non-stereo sections of the screen like the menus. The menus become less easy to read (and completely weird in mono) but they can be read in stereo. This is a GOOD THING. 2) - there is a handy-dandy button at the bottom of the display that switches the screen into stereo from mono, and works fine in both coot and pymol. Heartily recommended for the diehards who like having the z-coordinates of their models correct. adrian

Re: [ccp4bb] Stereo monitors for use with Pymol and Coot
Hi Alice, I've got an LG DM2352D-PZ passive stereo monitor, which seems to be comparable to the Zalman and works under the Zalman setting in coot and ccp4mg on my Mac. I've been happy with it, at least since I worked out some video settings (very different from the defaults) that made it easier to look at the screen for long periods of time. For stereo mode, it would be nice if it were higher than HD resolution, but I don't think the Zalman monitors were different in that respect.

Re: [ccp4bb] Stereo monitors for use with Pymol and Coot
Yes, my understanding too is that they all work at HD resolution, which is pretty unimpressive if you halve the vertical frequency. But that's what constitutes a cheap high-resolution screen this days. One can only wait and hope that people get into the 4K monitors, when life will become nicer for us.

Re: [ccp4bb] stereo monitor for DELL T7600
Hi Il, assuming that you work under Linux, be sure to get a Quadro 4000 with a 3-pin stereo connector (this is 'optional' according to Nvidia). The System will then work with the '3D vision System'. All compatible monitors like AcervGD235HZ or ASUS VG236H are listed on the 3D Vision site: http://www.nvidia.de/object/buy-3d-monitors-de.html You will aslo have to get a set of 3d Vision goggles and emitters. BTW, I would strongly suggest to stay away from the 3d Vision *PRO* goggles as we tested six of them and they all failed after less than 3 months of use! Apart from that the stereo quality is excellent compared to all previous stereo systems.

Re: [ccp4bb] stereo monitor for DELL T7600
Hi JI, Just FYI: we have a working setup of Nvidia 3D Vision on Quadro FX 3700 with Acer GD235HZ under Ubuntu 12. Quadro FX 3450/4000 was also tested (not officially supported by NVidia, but has all the capabilities) - although it works in principle, there was an annoying flickering effect I could not get rid of. In addition to what was already told here, I would recommend checking the monitor for backlight irregularities on 100% brightness before buying. This is the mode you are typically working in with the glasses (in fact, GD235HZ locks it at 100% when stereo is enabled), and the defects might not be noticeable on normal brightness.

Re: [ccp4bb] stereo monitor for DELL T7600
We use the ASUS VG278 monitor with built-in IR emitter under linux.Stereo works perfectly without 3 pin connector. Monitor is connected via (dual-link) DVI cable (stereo option 10 in xorg.conf). This should work with any Quadro card. The monitor is big and esp. bright in 3D due to it's NVIDIA 3D LightBoost technology (3D Vision 2). Much better for use of 3D in not so dark rooms. Christoph Andrew Purkiss schrieb: And that is because the emitter is powered by the screen and its presence is detected via the HDMI monitor cable (and the signal to the emitter is sent the same way). Use of these screens is via different driver option (stereo option of 12) and there is a more limited range available. I have no experience of running with this option, as being early(ish) adopters, we have a mix of Alienware OptX AW2310 and Samsung SyncMaster 2233RZ screens. I would be interested in how stable the stereo is, when a low powered graphics card is under heavy load. Having a graphics card with more power is not a waste of money (the CUDA drivers used by the molecular simulation groups show what can be done). The extra cost is quite small compared to the costs of getting crystals in the first place!!

Re: [ccp4bb] Stereo Microscope
Our setup is an Olympus SZX-10 with both 1x and 2x objectives and 10x eyepieces. It's nice having the different objectives for different things--a close up look at a tiny crystal requires the 2x, but the 1x is less bulky and has better depth-of-field, so it's better for freezing crystals. The DP21 camera is also nice, and provides for simple save-to-USB-drive photos and movies and scale bars, and also displays the field of view on an LCD monitor, which is nice for teaching and discussion among lab members. (To get the right value for the scale with a zoom microscope, though, it needs to be set up with the objectives as the zoom knob stop values and the adapter setting as the actual objective lens magnification. A bit of a workaround, but it's been fine for us.)

I do recall a bit of grief in that the default nouveau driver did not properly recognize the Q4000, possibly because it is a new model; so you will have to know what to do in text console mode to get the proprietary driver working.

[ccp4bb] Stereo solutions on the MAC?
Hi, Just curious if anyone has experience with stereo solutions on the MAC other than MacPro and stereographics glasses, or the Zalman monitors? Yes, the Zalman is cheap, and _ok_, but you lose half the horizontal resolution. If the monitor were 3600x2000 pixels, that wouldn't matter - but it's only HD. So - what about the stereo TVs Can the MAC drive those in stereo? Anyone ever tried? Adrian

This monitor has a built in emitter that works with the pair of nvidia (these are not generic active shutter goggles) 3d vision goggles it comes bundled with : http://3dvision-blog.com/review-of-the-27-acer-hn274h-3d-vision-ready-lcd-monitor/ ...but does not have an input for the 3 pin mini din coming off a proper quadro. The latest nvidia driver for linux still mentions that you need the 3 pin mini din for nvidia 3d vision stereo in linux: http://us.download.nvidia.com/XFree86/Linux-x86_64/280.13/README/xconfigoptions.html Option Stereo integer 10 NVIDIA 3D Vision mode for use with NVIDIA 3D Vision glasses. The NVIDIA 3D Vision infrared emitter must be connected to a USB port of your computer, and to the 3-pin DIN connector of a Quadro graphics board (based on G8xGL or higher GPU) before starting the X server. Hot-plugging the USB infrared stereo emitter is not yet supported. Also, 3D Vision Stereo Linux support requires a Linux kernel built with USB device filesystem (usbfs) and USB 2.0 support. Not presently supported on FreeBSD or Solaris. Having just the USB connected to the emitter still only works in windows with the standard emitter. I also know that the windows nvidia driver explicitly checks to see what sort of monitor you have before enabling 3d vision (see the nvidia 3d vision wizard in the nvidia control panel), i.e. that's probably why you don't need a USB cable connected from your computer to this particular monitor where the emitter is housed in the bezel. So, basically if you decide to go with this monitor you'll still probably need to get the 3D vision kit with the proper emitter and you'll also need to get the 3 pin mini din bracket for your Quadro 3800 since it doesn't have the 3 pin mini din output: There's a forum about it here : http://forums.nvidia.com/index.php?showtopic=96163 which leads to this PNY part # 900-50762--000 : http://www.google.com/products/catalog?q=900-50762--000cid=17694678402912029306ei=OoVzTvKqH6mExgXwi5HRAQved=0CAkQgggwAA#scoring=tp Ofcourse I have to install linux. Do I need to buy anything else(say emiter or connector) for 3D stereo set up in linux distribution. What linux you like to suggest? I am familiar with open suse or ubuntu. Either would be fine.

Intel Xeon W3550 3.06GHz or Intel Core i7-2600 3.40GHz i'd say the i7 2600 @ 3.4GHz, uses less power too. If they are not big difference, I will go with the first one and increase the hard drive. What do you think? Buy the 2nd one, get a quadro 3700, get the 3d vision kit, and if you want a 120Hz 27 LED monitor, here's one : http://www.buy.com/prod/samsung-syncmaster-s27a750d-27-3d-led-lcd-monitor-16-9-2-ms-adjustable/223430191.html that doesn't have a built in emitter which as mentioned above probably isn't going to work in linux.

Re: [ccp4bb] stereo
I run the Alienware OptX AW2310 on two of our 3D Linux workstations and it looks spectacular. Make sure that you have a Quadro FX Nvidia video card that is on the approved list ( http://www.nvidia.com/object/quadro_pro_graphics_boards_linux.html) with 3-pin stereo (3-pin stereo connector required for Linux, it will work without one in Windows through USB) output and not just a normal GeForce Nvidia card or you won't be able to run stereoscopic 3D in Linux. One option that supports both Mac and Linux are the Zalman brand 3D monitors. Some people like them, some people don't. Unless Zalman significantly improved the technology on their monitors (ie: the right eye can see odd numbered rows of pixels and the left eye can see even numbered rows of pixels) you lose a significant amount of resolution from displaying 3D on these. Due to half the pixels being drawn to each eye, the display on the 3D Vision system using a 120 Hz monitor will look crisper and higher quality than the equivalent Zalman monitor when displaying stereoscopic 3D. That being said, this solution is significantly cheaper than the Nvidia system. I've used and seen both and prefer the quality of the Nvidia 3D Vision, but some people are happy with the Zalman setup. It's really up to personal preference as to which you will choose.

Now if this works like 3D DLP link stereo then you don't necessarily need the 3D vision stereo kit/emitter at all. In fact, we have an Infocus IN3116 projector that does 120Hz at 720p and a bunch of $50 DLP link goggles, a quadro 3700 video card in the box, and can do stereo in Windows 7 and Linux using Option Stereo 3 (standard quad buffered stereo). We use a cheap $2 DVI to HDMI converter to connect a long HDMI cable into the projector from the Quadro 3700 and that's it, no super long 3 pin mini din cable is needed. The only downside is that sometimes the left and right eye images are on the wrong sides when stereo is enabled, but most apps (e.g. pymol, chimera, and coot too probably) have an option to swap the eyes when in stereo so that's easily fixed. I buy higher level quadro graphics card (say FX 5600), will it improve the stereo quality? How big difference the prices are? Thanks for your A better card won't improve the stereo quality itself, but will improve surface, vdw, etc renderings with high polygon counts. For building models, most people are looking at wireframes/lines which you can still do for huge macromolecules on an SGI Octane. So yes, the 5600 will work with nvidia 3d vision, it has at least a G8x core (http://en.wikipedia.org/wiki/Nvidia_Quadro) and the stereo connector in the back. If you decide to go with something like that Acer HS244HQ it would be interesting to see if it can be made to work without the nvidia 3d vision kit at all. HTH, Sabuj information.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
Hi, I tried upgrading the driver yesterday to the 270.41.06 version but it didn't make any difference, still only 100 Hz. Are you using Windows or Linux? We're using the 64-bit Linux driver. We had the same problem initially with the Asus VG236 until we went into nvidia-settings and turned off Force Full GPU Scaling for the monitor under the GPU settings. Usually this option is unchecked for standard 60 - 75Hz LCDs but I found this was checked for some reason, unchecked it and then the monitor went blank momentarily and came back. Then the refresh rate increased from 99.99Hz to 119.98Hz. The information menu in the monitor itself also showed 120Hz. This has to be applied for every user or you can copy ~/.nvidia-settings.rc to other users' directories. The system is currently using the 260.19.26 linux 64 bit driver running CentOS5.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
Hi, Eric and Carsten, If you are using Linux try launching 'nvidia-settings' and disable GPU scaling. My system was RedHat5 64-bit. I set the option at that time, though I forgot to mention it… nvidia-settings stores the settings into ~/.nvidia-setting-rc, therefore it is not system-wide. I also annoyed that I should launch nvidia-settings when I login. Instead launching 'nvidia-settings', I set FlatPanelProperties in xorg.conf as below. Section Device Identifier Videocard0 Driver nvidia Option Stereo 10 Option FlatPanelProperties Scaling = Native EndSection Hope it helps.

For example, with the last version of the Nvidia driver I tested, the driver refused to put out an Nvidia 3D Vision sync signal (stereo 10 in xorg.conf) unless there was a 3D capable LCD attached. I don't know of any technical reason the Nvidia 3D Vision couldn't be used with a CRT but Nvidia has apparently chosen to disable it (or at least make it hard to enable) in the Linux driver. Going the other direction, using RealD with and LCD system, it might be possible but you probably have to match your RealD emitter with RealD glasses. Older CrystalEyes glasses (CE3 and earlier) generally do not work with LCD monitors because of the polarization in the glasses. We recently got some CE4 glasses and they don't seem to have that problem although in practice we are using them with a projector, not LCD monitors. But I don't really like the CE4's, there is too much of my field of vision under the glasses that they don't cover. We've observed some really weird configurations that appear to mostly work, such as plugging in a RealD emitter and glasses when the driver is configured to output a signal for Nvidia 3D Vision (stereo 10 option under Linux). You don't say whether you are using Windows or Linux and there may be variations in the drivers, variations by card, etc. Regarding card to card variations, we've observed 3D setups in conference rooms with multiple emitters where some Nvidia cards happily drive multiple emitters with particular splitters boosters, but other Nvidia cards don't. The bottom line is if you mix hardware you might have problems and vendors are unlikely to help you. If you have CE4 glasses already, you can try it with an LCD and it may work. Otherwise, if you have to buy new glasses (ie, you have CE3 or older), you might as well get the Nvidia package with the emitter included. 3D Vision Pro uses the 2.4 GHz band instead of IR to transmit the sync signal so if you were setting up a conference room in theory the Pro version might be less likely to leave dead zones in the conference room. For a single user workstation it's very unlikely that you would get any benefit. Just to muddy the waters a bit, I have not seen a working 120 Hz stereo setup working on the Acer GD235 monitor. We have a bunch of them set up, and we put a 120 Hz mode line in xorg.conf. If you ask X11 it says it's running at 120. But if you ask the Nvidia driver or the monitor, it reports 100 Hz instead, and visually there is enough flickering that the monitor and the driver seem to have the correct number. I'm curious if anyone else here has looked in detail to make sure their Acer-based system is running at 120 and found that it is actually doing what people claim it can do. I find the 100 Hz LCD flicker annoying over long periods so I am still a neanderthal CRT user. My coworkers were convinced their LCD systems were running at 120, when they were actually only running at 100. I'm not sure if this is a driver problem or a monitor problem. -Eric On May 6, 2011, at 11:27 AM, zhang yu wrote: Dear colleagues, Sorry to present the stereo issue to the board again.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
1. No you cannot use your old stereo emitter. The 3D Vision Emitter is required for stereo on 120 Hz LCD monitors. You will also need new shutter glasses from Nvidia, but these some with the emitter. I'm not sure the reason, but I'd guess that the older emitter can't transmit the signal at the correct frequency to get 60 Hz to each eye. On a side note, consider which operating system you are running on the system to be used for stereo. You'll need the 3-pin stereo connector if you want to do stereo in Linux. For Windows it isn't required. Some computers that Dell and other manufacturers sell with FX3800 cards don't have one built in, and you will need to buy an adapter that hooks into the video card to provide the port. 2. The normal 3D Vision system uses IR signals to communicate between the emitter and the shutter glasses. 3D Vision Pro uses RF signals for communication between the glasses and the emitter and has a longer range and doesn't require line-of-sight like the IR system (hence the hefty price difference you've noticed). I don't believe the glasses from the normal 3D Vision kit are compatible with the 3D Vision Pro system due to the difference in signaling systems, but I haven't tested this. If you're going to be sitting in front of a monitor doing modeling and don't have alot of IR interference in the same room, the normal 3D Vision version will suffice for your needs. 3D Vision Pro is more geared toward having large meeting rooms and presentation halls equipped so everyone in the room can view 3D on a large screen driven by a 120 Hz DLP projector. 3. I don't wear prescription eye glasses, but I do have long modeling sessions without any discomfort wearing these. They come with several inter-changable nose-pieces so you can pick the one that fits you most comfortably.

I don't believe the glasses from the normal 3D Vision kit are compatible with the 3D Vision Pro system due to the difference in signaling systems, but I haven't tested this. If you're going to be sitting in front of a monitor doing modeling and don't have alot of IR interference in the same room, the normal 3D Vision version will suffice for your needs. 3D Vision Pro is more geared toward having large meeting rooms and presentation halls equipped so everyone in the room can view 3D on a large screen driven by a 120 Hz DLP projector. 3. I don't wear prescription eye glasses, but I do have long modeling sessions without any discomfort wearing these. They come with several inter-changable nose-pieces so you can pick the one that fits you most comfortably.

Re: [ccp4bb] Stereo solution with Nvidia '3D vision' or '3D vision pro'
We recently had issues setting up a 3D projector and have tried lots of combinations of monitors, drivers, cards, glasses, etc. The answer seems to be that interchangeability is very complicated and you won't know unless you try it. For example, with the last version of the Nvidia driver I tested, the driver refused to put out an Nvidia 3D Vision sync signal (stereo 10 in xorg.conf) unless there was a 3D capable LCD attached. I don't know of any technical reason the Nvidia 3D Vision couldn't be used with a CRT but Nvidia has apparently chosen to disable it (or at least make it hard to enable) in the Linux driver. Going the other direction, using RealD with and LCD system, it might be possible but you probably have to match your RealD emitter with RealD glasses. Older CrystalEyes glasses (CE3 and earlier) generally do not work with LCD monitors because of the polarization in the glasses. We recently got some CE4 glasses and they don't seem to have that problem although in practice we are using them with a projector, not LCD monitors. But I don't really like the CE4's, there is too much of my field of vision under the glasses that they don't cover. We've observed some really weird configurations that appear to mostly work, such as plugging in a RealD emitter and glasses when the driver is configured to output a signal for Nvidia 3D Vision (stereo 10 option under Linux). You don't say whether you are using Windows or Linux and there may be variations in the drivers, variations by card, etc. Regarding card to card variations, we've observed 3D setups in conference rooms with multiple emitters where some Nvidia cards happily drive multiple emitters with particular splitters boosters, but other Nvidia cards don't. The bottom line is if you mix hardware you might have problems and vendors are unlikely to help you. If you have CE4 glasses already, you can try it with an LCD and it may work. Otherwise, if you have to buy new glasses (ie, you have CE3 or older), you might as well get the Nvidia package with the emitter included. 3D Vision Pro uses the 2.4 GHz band instead of IR to transmit the sync signal so if you were setting up a conference room in theory the Pro version might be less likely to leave dead zones in the conference room. For a single user workstation it's very unlikely that you would get any benefit. Just to muddy the waters a bit, I have not seen a working 120 Hz stereo setup working on the Acer GD235 monitor. We have a bunch of them set up, and we put a 120 Hz mode line in xorg.conf. If you ask X11 it says it's running at 120. But if you ask the Nvidia driver or the monitor, it reports 100 Hz instead, and visually there is enough flickering that the monitor and the driver seem to have the correct number. I'm curious if anyone else here has looked in detail to make sure their Acer-based system is running at 120 and found that it is actually doing what people claim it can do. I find the 100 Hz LCD flicker annoying over long periods so I am still a neanderthal CRT user. My coworkers were convinced their LCD systems were running at 120, when they were actually only running at 100. I'm not sure if this is a driver problem or a monitor problem. -Eric On May 6, 2011, at 11:27 AM, zhang yu wrote: Dear colleagues, Sorry to present the stereo issue to the board again.

Re: [ccp4bb] Stereo Microscope advice
Hi Kevin - 1) I can only imagine that LEDs would produce vastly less heat than halogen lamps. In general, they are small, efficient, long-lasting and don't produce a lot of heat. Here's a start for more information http://en.wikipedia.org/wiki/Light-emitting_diode . Also, a quick search got me this page http://www.tedpella.com/mscope_html/2282.htm which has what appears to be all the options you mentioned. I'm sure other manufacturers have similar models. 2) We are generally satisfied with our older model Olympus . If you will be looking at drops smaller than 1μl total volume (e.g. from a mosquito or other sub-μl liquid handler) I'd recommend at least a 2x objective lens. Some models (like the one linked above) have an option to direct the light to a camera mount instead of the eyepieces--get one of these if possible!

Re: [ccp4bb] Stereo Microscope advice
Hi Kevin, We have 3 Olympus microscopes with three different lighting options. The three variations we have on our microscopes are: 1. a microscope with a reflective light base (internal mirror) that reflects light directed into the microscope base from an external halogen light-box. 2. a microscope with an integrated, low-power (30 watt) halogen light source (still has a mirror for the trans-illumination) 3. a microscope with an LED light source In general, the LED light source in our microscope produces very little heat so crystal trays should be safe for viewing for quite some time without heating. And, instead of a mirror, the base has a series of filters/diffusers to modulate the intensity of the light directed through the sample, or a dark-field filter. That can be helpful. However, the spectrum of light output by our LED light source is very blue (as opposed to the warmer yellow-heavy output from halogen or incandescent light sources). I don't like the cold, blue tones of the light and find that it contributes to eye fatigue. I also find that this light doesn't offer as high a contrast for viewing certain drop conditions. By that I mean that I occasionally find drop conditions for which I feel I can see differences in edge transitions or object boundaries better using the microscopes with the halogen light sources (i.e. comparing same drop with different microscope/light-source combinations). This doesn't happen often and does not dramatically affect my ability to rate the drop, but it's notable to me. In summary, I prefer alternatives to the LED light sources, but my dislike of the output spectrum is a matter of opinion. NOTE: My understanding is that the blue-heavy spectral output of white-light LEDs is a recognized property of LEDs (i.e. it's hard to achieve a true white light with LEDs). However, the ability to produce LEDs that have a more natural spectra is improving and I know at least Olympus is very close to offering such a version (more $$). With regards to polarizers, we just use screw-on polarizing filters that attach to a channel/groove near the bottom of our objective lenses. These are convenient and inexpensive (works with any light source). They won't, however, fit on all objective lenses depending on the presence of the necessary groove. -Andy Torelli -Original Message- From: CCP4 bulletin board [mailto:CCP4BB@JISCMAIL.AC.UK] On Behalf Of Kevin Corbett Sent: Sunday, January 23, 2011 8:35 PM To: CCP4BB@JISCMAIL.AC.UK Subject: [ccp4bb] Stereo Microscope advice Hi everyone, I'm looking to buy a new stereo microscope for looking at crystal trays, and was wondering if anyone could help me answer a few questions: 1) Does anyone have experience with LED illumination in the microscope base?

Re: [ccp4bb] Stereo Microscope advice
'White' LED light produced by most integrated white LED packages is in fact a mixture of blue (~460nm), produced by the LED itself and a broad-band yellow (560nm), produced by a secondary phosphor, typically directly coating the semiconductor that emits the primary light. The net effect is a single-source mixed-wavelength light. The eye does not immediately notice the dip in the spectrum around the green (notably, the eye is in fact tuned into green for maximum sensitivity so the spectrum 'appears' smooth to us when in fact it's anything but). These LEDs are awesome for many applications and they indeed do not generate as much heat as incandescent lightbulbs do, but several folks I know have noted that their eyes are more tired after viewing LED-illuminated samples under a microscope. http://powerelectronics.com/power_management/led_drivers/Fig-2-white-LED-vs-RGB-LED-spectrum.jpg Other types of 'white' LED lights employ carefully balanced mixtures of three primary colors, each produced by a separate quantum well. Unfortunately these lights tend to shift colors with temperature and with age and appear different from different angles - feedback compensation is required for precision use. These tend to be much easier on the eye (at least to me), but I am not sure whether any scopes come with these composite LEDs installed.

Hi there is at least one other option - we have a Planar Systems 3D setup (uses two flat screen monitors mounted at ~right angles with a semi-silvered screen between them) - you use polarised lens glasses to view the stereo. It works extremely well, but is pricey. If you have a good workshop they could probably knock up an ersatz copy for you at somewhat less than the retail price. http://www.planar3d.com/ Their entry level setup is advertised at $2395 - which is probably enough to put most people off, but the stereo is *very* good.

Re: [ccp4bb] stereo (again - sigh)
Thank you all for the quick replies. I did leave out some specs, but I really wanted to know what others have found. Sadly, it's no different than my findings. I am at a small undergrad only university - low on resources but big on ideas for teaching students. This is not research based, so I don't have a grant to buy one system for research (I do solve structures and I can buy one system, but I need more for a class). Instead, I'm trying to teach a class - we have 6 workstations that are shared among the students. We solve a crystal structure as part of this class. Stereo is nice but not necessary - though as a teaching tool it's invaluable. Switching to the nvidia system works - we have that here for one classroom - the problem being active stereo is a nuisance. It can flicker - looking away can cause problems (with a larger classroom), and it's just not the way to go (the glasses are expensive, I can go on and on). I think passive stereo is the beat all end all - but I can't buy a zalman monitor to save my life (I have literally had 3 of these in shopping carts - and one went as far as to charge my card only to refund me 3 days later due to lack of stock). That does make me worry as to replacing it later in life should I get 6 and they crap out on me. When I was at Argonne, they have a polarizing filter that fits on the front of a monitor. You can turn it on and see stereo through that, I think it's basically a Zalman filter. Does that sound right - and if so - is that something somebody out there has? Thanks again - your help is invaluable. By the way - if I ever do replace this, is anybody in the market for some old emitters, video cards, and glasses (I have 14 pair of the 3D glasses - crystal eyes knock-offs, sorry the company escapes me at the moment, but they are good glasses).

The Zalman passive stereo route, which you tried, or the active stereo route, which means an Nvidia 3d Vision emitter/glasses combo and a 120 Hz LCD. The glasses/emitter kit is here: http://www.nvidia.com/object/product_GeForce_3D_VisionKit_us.html And you need an Nvidia Quadro FX 3700 or higher to run them on linux: http://www.nvidia.com/object/quadro_pro_graphics_boards_linux.html There are several 120 Hz LCDs available right now. Some links to models and additional info on set up are on our website: http://sbgrid.org/wiki/install/stereo I hope this helps. -ben -- | Ben Eisenbraun | Software Sysadmin | | Structural Biology Grid | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |
Re: [ccp4bb] Stereo Mac OS X - Update
1) A couple of people like the Zalman BUT when I contacted the vendor recommended on the WIKI here's the response (edited).

We are totally sold out of these and Zalman is not providing any firm ETA from factory in South Korea, extreme\ shortage, ETD around mid-Sept as of now….. can put a backorder in my Los Angeles warehouse ... am not sure how many pcs can be allocated. $429.00 ea - Zalman LCD ZM-M215W 21.5in Wide 1680x1050 1:1 5ms DVI 3D Black Retail 2) For those with Quadro cards Alienware 23 inch 120 hz display has been suggested by somebody building a system, but they do not have it installed yet.

Re: [ccp4bb] Stereo Mac OS X - Update
I can give general info about current stereo LCD solutions, but I don't know which ones work and/or are supported on Mac OS. The Zalman monitor may be scarce because it is being replaced by something newer; the 1680x1050 resolution has been replaced by 1920x1080. The specs you list appear mistaken, the ZM-M215W is one of the 1920x1080 models. I don't know about prices or availability. Newer monitors: ZM-M215W is a 1920x1080 monitor, 21.5. Zalman ZM-M240W is also 1920x1080, but is 24. Older monitors: ZM-M220W 22 1680x1050 ZM-M190 19 1280x1024 discontinued - As for 120 Hz monitors which work with nVidia 3D vision active glasses: Older, 1680x1050, 22 monitors: Samsung® SyncMaster 2233RZ ViewSonic® FuHzion VX2265wm Newer, 1920x1080, 23 monitors: alienware OptX AW2310 ACER GD235HZ ASUS VG236H (Monitor surface is glossy, not matte) HP 2310g Not available yet, but perhaps some time this year: LG W2363D ViewSonic V3D241wm-LED (with LED backlighting) ASUS PG276H (27 rather than 23, but still 1920x1080 resolution) So far I have one Linux system set up with a Quadro 3800 card and the Acer GD235HZ monitor.

[ccp4bb] Stereo Mac OS X - what current options?
I searched the BB and this has been discussed on and off over past year. If any one has setup a Mac for stereo with COOT using LCD with currently available hardware please post details. Thanks :)

Hello, FYI the 3D glasses distributed for viewing the Avatar movie can be used to view structures in COOT using the Zalman monitor. Regards, Jay Maria Jamela R.

Re: [ccp4bb] Stereo
Yeah, only the RealD goggles, the ones that look like these and that are given out at standard (not IMAX) movie theaters: http://www.google.com/products?q=reald+3d+gogglesscoring=p will work. Several users brought back the IMAX goggles that look like these (might be yellow): http://www.3dglassesdirect.com/polarized_3d_glasses.html but these do not work. The difference is that the IMAX goggles are usually linearly polarized as mentioned in the 2nd URL above. The RealD goggles are circularly polarized which is the stereo tech that Zalman uses.
