This format will generally only run on the high-end projectors, such as
Barco or Electrohome. The SGI shipped monitor definitely won't display it as
the horizontal rate is too high.
> 1024x768_120s.vfo
This is at the edge of what most monitors can display. You don't say which
monitor you have, looking at the horizontal rates in the manual and comparing
them to the values for this format in /usr/gfx/ucode/KONA/dg4/vfo/README
should give you an idea as to whether this should work or not.

The IR can do it, it is a matter of finding a display capable of these
speeds. If you are using SGI shipped monitors, sticking to 1024x768_96s is
probably your best bet.
