We successfully used the Gforce 3D vision kits with the Linux 195.30 driver on the Samsung / Viewsonic 3D displays under RHEL5 (on both 3450 and 3700 Quadro cards) to display quad-buffered stereo graphic applications. The displays look great and work fine in 3D with on our workstations.
Given the success of these tests we are getting ready to replace many of our old stereo CRTs. We would like to use the newer 23.6" 3D monitors from Acer and Alienware for the bulk of the replacements. In our initial tests with the new 23.6" displays, the top 2" of the screen does not go into stereo. We based our xorg.conf file on the working ones from our initial 22" display tests correcting for the increased resolution on the 23.6" displays. Except for a bar at the top of the screen which will not go into stereo, the stereo appears to be functioning normally. Are others seeing this problem? I remember reading somewhere in the driver release notes that future panels would need to be tuned for optimum performance. Is the problems we are seeing a problem with the driver, and if so, when can we expect a new version that has been tuned to these displays. Has anyone gotten these new displays to work in stereo properly. Any help would be appreciated.

I would really like to see your xorg.conf setup. What applications did you test on as well. Cheers -Arjay

Update - Tried dual monitor configuration with a pair of other Alienware screens on another machine. The same problem on both screens as I saw with one screen. The glasses sync seems to be off for the top 2-3" of the panel allowing you to see both images and loosing the 3d effect. I also tried the newly released 195.36.15 driver - no change.

I also tried the Alienware LCD with Quadro FX3800 under RHEL5 + 195.36.15 driver,
and experienced the same phenomenon --- ghosting in the top 1/3 area of the monitor.
(Tested by glxgears -stereo, with a single monitor, not TwinView.)
I also noticed that the monitor was drived at 1920x1080@100Hz though it can work at
1920x1080@120Hz, thus I felt some flicker. I wrote a Modeline option in xorg.conf
to force 120Hz but it was ignored. Is this a bug of the driver?
Bob, Thanks for posting your conf files and I did end up using as a reference -- sorry for the late post. Just picked up the Acer 27" and working with it now. Will post my results. Cheers - Arjay
