Oh dear, not the Ostendo CRVD or Alienware 2880 x 900 rear-projected DLP screens. The resolution is too low.
I'm using 1x 23" displays as centre and 2x 23.6" side displays. The view is great and TrackIR solves the look-up 'problem'. The TrackIR view-change left/right in game I could cut in half and use the corner of my eye, as it were... much more realistic.
3x1920x1200 would be better that the 1080 ones. A dream is projectors, of course. One could start wit 2, as matching the edge of the projected images together is possible, unlike 2 monitors.
