[Chimera-users] stereo

What you need to do is a variation of option 1.  Here is a rehash of 
everything you have to do.  I don't have access to the a Quadro today, 
so some of the latter details will be from memory.

First, remove the consumer stereo driver.  The Quadro driver has its own 
stereo support.

Next go to www.nvidia.com, select "Download Drivers".  In the three 
columns, pick "Graphics Driver" in column 1, pick "Quadro" in column 2, 
and pick "Windows XP/2000" in column 3. Then press the "Go!" button. 
That takes you to 

Next, since chimera isn't listed, pick the "Windows XP/2000" link in the 
Quadro FX.  The driver works for the Quadro4 as well.

I believe you have already successfully done all of the above steps.

Next bring up the Display dialog (start / Control Panel / Display), switch 
to the Settings tab and press the Advanced button.  The resulting dialog 
should have many tabs (General, Adapter, Monitor, etc.) and one of the 
tabs will be the name of your graphics card, in this case Quadro4 900 XGL.
Pick the graphics card tab and you'll see the NVidia control panel.

Here come the crucial step.  NVidia has moved the stereo settings around 
in the control panel from one driver release to another.  Sometimes you 
will see various Stereo items listed in the associated popup menu to the 
left of the dialog, like what you see when the consumer stereo driver is 
loaded.  But if that is not there, you will need to go to the "Performance 
& Quality Setting" subpanel, and change the View from "Basic settings" to 
"Advanced settings", then in the scrolled table just below it, you will 
see the stereo options.  And after you set the right stereo options, you 
will get stereo.

If the above doesn't work, on Monday I can sit down in front of a Windows 
XP machine with a Quadro4 900 XGL and find out exactly what needs to be
