This is an Infinite Reality, 2RMs gives you enough screed real-estate
for 4++at++1280x1024, If you want to drive these at 60 Hz then you won't
have the bandwidth on the DG4 so you'll have to settle for
3++at++1280x1024_60+another_small_format.
Again, small pixel depth supports 4 sample anti-aliasing, so it isn't
possible to configure an iR managed area which doesn't support some
anti-aliased visual.
If you have an iR you can anti-alias with the correct visual.
Rgds,
Angus.
