Hello,Sorry, if this question somewhat off-top to the actual discussion, but to my understanding one does need the 3-pin connector to operate 3D under Linux even for the monitors with the built-in emitter. It appears to be necessary to guide the emitter, or am I wrong about it? I'd be thankful if anyone can advise me on that since it looks like a big problem to acquire the commercial connectors and cables.
I think I have seen an older discussion on CCP4BB where the importance of the 3-pin connector was emphasized...

Hello Moutse,
as you noted correctly, the ASUS VG278H (HR or HE) comes in two flavours, one with build in emitter (120 Hz, HR model) and one without (144 Hz, HE model).
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.
Have a look at the following link http://www.nvidia.com/object/3d-vision-pro-requirements.html, especially the table at the end with the small print explanation "2" and "3"

Hi,
I am currently also looking for a 3D monitor, and I am particularly attentive to this particular discussion. My interrogation is that does the Asus VG278HE model work under linux ? From previous ccp4bb discussions I understood that only built-in emmitter (like the Asus VG278HR) are suitable for that, but maybe I misunderstood...
Thank you very much for your help,
Moutse.

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
