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.

Subject: Re: [ccp4bb] Stereo monitors for use with Pymol and Coot

Hi,

this is probaly due to the transition from old TFT style to new IPS panel based 
monitors... Several new passive 3d monitors are hitting the market such as AOC 
d2769Vh and the Philips Gioco 278G4. Both are based on 27" IPS Monitor panels. 

A list of possible monitors can be found at Tridef (many are old but new models 
are listed),  https://www.tridef.com/products/pc-licensed-products.

Problem with passive stereo is, you will half the resolution in the vertical 
direction. It is a problem if you are looking at wire-models of structures in 
pymol and especially fine-wire electron density mesh and models in coot as 
those noticably loose resolution compared to active stereo screens. 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. 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....).

A rather US-centric question on passive 3D monitors...

I'm just getting set up in the US, and I'm surprised on how few passive 3D 
monitors seem to be around - many models seem listed as 'out of stock' when 
looking in the usual places (Amazon, NewEgg, BestBuys, Walmart etc.)

The best deal I have found is for an LG D2343PB-BN 
(http://www.lg.com/us/commercial/lcd-computer-monitors/lg-D2343PB-BN) at US$274

Does anyone have any experience with this model, or any suggestion about where 
best to buy 3D monitors in the US?

many thanks in advance

Shaun
