I use a 47inch, its awesome. no doubt... But be aware, that the Matrox TH2go will not support 3 monitors at full 1920x1080res as of yet..
That equals 5760res in the horizontal plane, which is just beyond the capacity of the Matrox unit... With a lower resolution, it will work...
I've read that the next version of Matrox will handle it tho.. Hope so, I'm looking forward to that!!
Triple head gives a wider FOV... But I luv the giant monitor, because I can SEE more (lifesize), than just a tiny speck of a target..
Either way, Its a big improvement, and well worth the expense..
