Re: [PyMOL] Caution - 120 Hz LCDs: Not CRT killers yet...
Hi I am wondering if there is a linux nvidia driver update or any other hack that allows Crystal Eyes 3 stereo products to work with the LCD 120Hz flat panel monitors. I should have read Warrens warning post (Dated Jan 23 , 2009 [ccp4bb] Caution - 120 Hz LCDs: Not CRT killers yet) , before purchasing the Viewsonic VX2265wm 120Hz LCD. But my CRT died last week and since I was addicted to pymol/coot-in stereo ( with Crystal Eyes 3 ) , I rushed out and bought this 120 Hz LCD monitor. Of course things dont work . And I am wondering if there is any update from nvidia or any other workaround that allows me to get stereo on this setup.

Re: [PyMOL] Caution - 120 Hz LCDs: Not CRT killers yet...
Hari Others, At this moment, the LCD flat panel to buy for use with PyMOL is the Zalman M220W (scan-line interleaved, passive stereo 3D). Unfortunately, last week's nVidia driver updates do not contain the expected support for 120 Hz LCDs from Samsung and ViewSonic. However, my personal belief and conviction is that they will be supported in the near future, and that they will work with PyMOL -- at least under Windows XP and Vista. Furthermore, having personally tested the stereo 3D capabilities of both the Samsung and ViewSonic displays with nVidia 3D Vision emitter and glasses, the Samsung 2233RZ is so much better at generating a clean, nearly ghost-free stereo 3D effect, that I plan to strongly recommend the Samsung 2233RZ over the ViewSonic VX2265wm, if (when) nVidia releases their stereo-3D-capable OpenGL drivers for 120Hz LCDs. Whereas the Samsung's 3D effect is equal to, if not better than a CRT, the ViewSonic is clearly inferior to both -- at least in my experience, using nVidia 3D Vision glasses. Hopefully ViewSonic's future 120 Hz products will be more competitive! So recap: If you need stereo 3D-capable today, then buy a Zalman M220W http://pymol.org/zalman . That display will work with Mac, Windows, and Linux, without need of any special graphics card. You give up half the vertical resolution, but hey -- it works today, and it works quite well. However, if you expect to need a stereo 3D capable LCD in the future, then plan on buying a 120Hz Samsung 2233RZ with the nVidia 3D Vision glasses and an updated Quadro graphics card. This will give you same high-quality, full-resolution 3D effect as a Crystal Eyes-based CRT setup. But please do wait until the critical drivers are released before spending any money, and realize that you may be stuck using Windows for the time being.

Reportedly, there is a driver update coming that will target use of nVidia's 3D vision glasses with Quadro-based graphics cards, so stay tuned. Just in case anyone wants to track this, here is the source I found of that report: Quad Buffered Stereo will be supported with the NVIDIA GeForce 3D vision glasses in upcoming driver release by spring 2009. http://www.nvidia.com/object/quadro_stereo_technology.html -- Thanks, Donnie Donnie Berkholz Developer, Gentoo Linux Blog: http://dberkholz.wordpress.com pgpwVfcb9EgcZ.pgp Description: PGP signature
