Hi, Since it is mentioned, I would like to take this chance to clarify:
We have used the Zalman and LG 2342P under Linux, Windows(XP and 7) and a VM Windows within a Linux system, on either desktop (with a minimal on-board graphic chip) or laptops. The monitor is quite plug-and-play in all cases we have tested. According to the internet, these monitors also work with Macs for stereo game play and stereo video viewing. In regard to the crystallographic software, the Zalman mode is supported by COOT, Chimera, and the new Pymol (but not the 0.99) - we have tested them all in both Linux and Windows. Passive 3D only requires the graphic program to send out the left and right images in alternating lines. To my understanding this suggests that it is independent of OS or graphic cards. But for Mac users, I think the first thing to check is whether the Mac COOT and Chimera has a Zalman mode option. Here's the link to my previous reply on the BB regarding our experience with the Zalman and LG D2342: http://www.mail-archive.com/[email protected]/msg28113.html Zhijie From: S K Sent: Wednesday, February 13, 2013 3:37 PM To: [email protected] Subject: Re: [ccp4bb] GeForce Graphics cards Harry, I found this on pymol wiki "NVidia 3D NVision kit only supports DirectX software for GeForce (gaming cards) on Windows; users are reporting that they are not able to run PyMOL with NVision with these cards. Get a newer model low end quadro (> G8x graphics core) without the 3 pin mini din (e.g. Quadro 370) or with the 3 pin mini din (e.g. Quadro 3700) for Windows." and this too " The GeForce cards do not support windowed openGL stereo, so we do not support these series of cards for the NVision 3D solution. For linux, you must have a quadro card that has a 3 pin mini din connector. The cheapest/oldest card that will work with linux is the Quadro 3700. WARNING: The Quadro FX1400 does not support 3d vision stereo on Windows7 or Linux. " This was posted there a while ago and I was wondering if there has been any update to that which has not been posted. Regarding the passive monitors, I think they are compatible with linux, after all we have been using zalman for long time, which is technically a passive 3D monitor. I also found posts on the ccp4bb from people happily using LG D2342P monitor, though linux or windows was not mentioned.

As far as stereo is concerned, Geforce cards only give stereo under Windows, not Linux. If you want stereo under Linux you need the Quadro cards with the stereo option (for example, Quadro 4000 or 5000). Not all Quadro cards support this option, and so would only give stereo under Windows, like the Geforce cards. Not sure about the passive type of stereo; I have a feeling that will also only work under Windows. I'm also not sure it works with Pymol and Coot. Perhaps someone can clarify this. As far as I know the stereo under Linux is only the active variety, using the NVidia 3D Vision glasses.

My searches on pymolwiki and ccp4bb archives resulted in the following conclusion: Coot and pymol are not compatible with the new GeForce graphics cards. Hoewver, most of the posts I found were from 2009 and 2010. Does anyone here have any experience with GeForce 660 or 680 for stereo applications of Coot, Pymol or UCSF chimera? Will quadro cards work equally smooth in the stereo mode of these programs? Do 3D applications put too much pressure on the Graphics card which would justify installing dual Graphics card? (not sure if is relevant, but just for the record, we want to buy passive 3D monitor due to the budget restrictions). Thanks, Alex
