I was using my TripleHead
2Go with 2 P1110s (21" Trinitron CRTs) and an old Dell 17" CRT (curved). Considering the size/shape/geometry mismatch, this still looked great.
However, I added a third P1110 and I love it (unsurprisingly). I do not like the 2D desktop management software provided by Matrox, so I was using only two monitors in 2D through my 2 ports on my 6800GT and running the TripleHead
2Go in single-monitor mode on the desktop. I am still doing the same, but now I have the third monitor as well, powered by an el-cheapo 6200LE TC. I change the left and right P1110 inputs (they are dual-input monitors) when I game in triplehead. This gives me the superb dekstop management I get with UltraMon and still gives me triplehead gaming on matched screens.
