I can confirm 5040 x 1050 with Catalyst 10.2 .
I have a 4870X2. In case it helps..
I did a fresh installation using a 4th monitor. After I installed all necessary drivers, I installed PowerDesk.
Then I connected the USB cable to my TH2GO (DVI Edition) and then the 3 monitors.
After that and following the setup, I did see the 1680x1050 (independent mode).
The pc rebooted and then I had 5040 x 1050 on my 3 x 22'. I am rock steady for the past 3 days now and never had issue. Lets hope it s
I have been trying all afternoon just can't get my ATI 5850 @ 5040x1050 on triplehead2go :(
Any help appreciated.
