I see they mention MGRAS alot for the SOLID/HIGH/MAXIMPACT cards... Just curious where the O2 fits into all of this.
Nicoya's page talks about IMPACT only.
See http://dart.ncsa.uiuc.edu/slevy/o2-stereo/ and http://niri.ncsa.uiuc.edu/slevy/o2-stereo/highres.html for information on applying the process to the O2.
I am currently in the process of creating a 1440x900_60 mode for my O2. The monitor I have is a Fujitsu W19-1 wide TFT. My initial attempt resulted in the monitor thinking it was in 1152x864, so even though there were 1440 by 900 pixels the screen did a pretty bad job of it. I've just checked the X.org modeline that works on my Linux box with this monitor and will shortly be booting up the O2 to try again. I imagine I would be posting any results to the Usenet comp.sys.sgi. something newsgroup, though, being slightly old school...
Update... It was a complete no-brainer with Stuart Levy's instructions.

That's all! Really! With FPS 60 the monitor just croaked, but I checked the Linux modeline I had, which resulted in a 62 Hz frame rate, so I upped that here too, the hsync freq went to 58.something kHz from the original 56, and the flat panel cooperates now!
