Hi there,
I am currently trying to do the same thing. I used ircombine to
configure two 1024x768_96s channels on each pipe after I learned that
unfortunately two 1280x1024_120s channels per pipe are not possible
due to bandwidth limitations.
First thing I noticed was the image being blurry with some strange
interlacing artefacts on one of our newer SGI monitors. The older
monitor models I tried just showed a pitch black screen.
To my great horror our Electrohome Marquis 8500 beamers only
displayed noise and complained about some h-sync problem. This
makes me suspect that something is different about the new
1024x768_96s stereo video format on IR besides the one pixel
difference (On the RE we had 1025x768_96s).
Currently I'm using two 640x480_120s channels, which works just
fine to the point that the low resolution is not acceptable. Also,
if anyone has some suggestions to cope with the stereo sync problem
on two pipes I would be grateful.
Henrik
