Hi there,
Most modern monitors are very clever and tell the X server their
preferred sync rates (which never exceed 85 Hz). You can override
this functionality by adding
OptionUseEdidFreqs0
to the Device section of your Xorg (or XFree86) config file.
You will also need to specify your own Modeline to control the monitor
timings. The program 'gtf', which should come standard in most linux
distros, will help you do this. Typing 'gtf' without args will give
you a short blurb on how to use the program. Shove the modeline
output by gtf into the Monitor section of your Xorg config file, set
this new modeline as the default timing in the Screen section of the
config file, and you should be in business.
HTH,
Stephen

Hi all -
While on the subject and after thanking Warren for providing the excellent
resource ...:
We have some nice 3D monitors and Nvidia cards in Linux PC's we do stereo
with.
Warren correctly points out that you need:
1280x960 @ 120 Hz requires H-sync of 123 kHz
1344x1008 @ 120 Hz requires H-sync of 130 kHz
1400x1050 @ 120 Hz requires H-sync of 136 kHz
(In fact you need your monitor to switch to these refresh rates only when in
stereo, but thats a detail)
However, I am totally unable to convince the NVidia drivers we have for
Linux to
operate at the sync rates I want them to and Warren advices! Thus, we have
noticeable flicker at stereo
mode (in the non-stereo windows only) which is a shame, given our excellent
monitors.
Is that expected or can be corrected ?
Could anyone please advice me how to set the Nvidia Linux drivers to operate
at the proper sync rates then ?
Tassos
PS - Iiyama Vision Master Pro 514 / HM204DT (H-sync: 142 kHz) is still
available by some European vendors new and is great, we have two, plus an
old trusty EIZO T966 which is also cool. (Warren, I could not find that on
your list,its a good machine, does 136 and you might be able to find one
still)

Folks,
Whether you favor Macintosh, Linux, or Windows for stereo 3D
visualization, you're going to need some specific (and increasingly
rare) hardware.
To help you find it, we've just updated our information page on
stereo-3D-capable displays, cards, emitters, and glasses:
http://pymol.sf.net/stereo3d.html
Remarkably, we can now only find one company selling a brand new CRT
monitor suitable for stereo 3D. If you find any others, please do let
us know!
Cheers,
Warren
