Hi, Jeroen
The Vuzix VR920 should provide a cheap 3D stereo alternative to CRT
monitors, because it contains two small LCD screens - if one displays
a right eye view and the other a left eye view we'd have a situation
similar to older display systems, with side-by-side stereo and a 3D
viewer with mirrors. Afterglow and flicker wouldn't be a problem
because each LCD would always receive the same eye view. In Linux
with an NVIDIA Quadro card, this might (?) be achieved by option "4"
TwinView clone mode stereo, provided each LCD can be perceived as a
single display.
Regards,
Pedro.

Dear Pedro,
there is no cheap solution for now, the 3D community has to wait for a
few years more I think to be presented with a good stereo-capable LCD.
The problem is not the refresh rate (as low as 5 ms nowadays) but it is
the after glow effect... that is one of the reasons why LCDs provide a
stable picture at just 60 Hz refresh rate in contrast to CRTs that look
stable at 85 - 100 Hz.
The cheapest solution is still the good old CRT (there are still a few
around) with nuvision stereo glasses.
For example, you can still buy the Samsung SyncMaster 1100MB that has
sufficient rates (Vert x Hori 160 Hz x 130 kHz) to do the job.
If you can, wait a few years ...
Jeroen.
p.s. There are also some (more expensive) active stereo beamers around
(we own an Infocus DepthQ) and they provide a nice active stereo picture
on the wall:
