We run VR-stuff on a Onyx with one RE2 and a MCO for dual channels.
We have 4xRM4s and the revisions are : 00112/00112/00112/00112.
We use the n-Vision HMD with a stereoscopic setting.
We have succesfully used the following commands for 180 Hz field-sequential:
./setmon -x -s b 640x480_180q (640x480 monoscopic)
./setmon -x -s b 1280x960_180qi (1280x960 monoscopic)
./setmon -S -x -s b 2++at++640x480_180q (640x480 stereoscpoic)
The last command use the MCO option ( -S ) and we always use stopgfx and
startgfx to restart the graphics. Sometimes the sync does not follow the blue
and therefore the clour fails. We use the syncs from two of the MCO-channels
and connect them to VS and the HS inputs on the HMD electronics box.
The first time we tested a field-sequential device we also experienced problems
with colour and after a while it was discovered that our RMs were too old.
Upgrading the RMs to revision 00112 made a big difference, though it took the
SGI guys here in Sweden a while to figure this out.
So, my guess is that it is either the revision of the RMs or the sync.
Good luck !
