I know its months ago but I would like to throw my 2 cents in:
Afaik Eyefinity only works with 3x the same resolutions - same as Matrox TH2Go. You may use 20/24/20, as I do at the moment, only via SoftTH. Looks like this:
5120x1200:
2 x 20" 1600x1200 will not look right, as it is or different pixel-pitch (0.27 vs 0.255), even if you can run them using SoftTH style.
Right but it will fit well with 20/30/20 - this is what my current goal for next spring is:
But becaus of Eyefinity and a potentially coming new Matrox with resolution up to 3x1920x1200 I´m also thinking about 3x27" triplehead - same power rquirements as 3x24 but huge display. :shock: Dunno what to do...
What I really would like to see is a proper support of 20/30/20 with Eyefinity and/or Matrox TH2GO - you will have 1600 pixels in height which is a much better trade in than having more horizontal pixels with 3x24" or 3x27".
