I've an ASUS EN7900GS, fully QE/CI with Natit Dual v0.02 (with titan all ok but not dual display) with dual DVI port. My problem is about the same but in a point different: i've two LCD: a ) SyncMaster 930BF 1280x1024 (19") b ) SyncMaster 203B 1400x1050 (20") using ( a ) as first and ( b ) as second monitor, i obtain a correct dual display with wide desktop (i don't need mirror), but the problem is that i cannot obtain a resolution higher than 1280x1024 (e.g. 1400x1050) on the ( b ) monitor. They all are flagged at a max of 1280x1024 and SystemProfiler view them as "SyncMaster" 1280x1024@75 (just tried at 60hz but nothing). swapping ( a ) with ( b ) i obtain that (strangely) that the ( b ) monitor now as first, is black, and the ( a ) monitor (now second monitor) is at 1280x1024 (his max) with the second part of the desktopn without dock and icons. I can confirm that the desktop is still wide but i can't only see it. If i suspend and resume osx from power button, i can now see the desktop in the before black screen but all is now freezed (mouse no more moves). Now the problem is not the freeze of suspend, but: HOW can i obtain OSX to see a possible resolution higher than 1280x1024 on the 20" monitor (that can do 1400x1050)? With intel integrated card with dual (DVI + VGA) output i can use the two monitors at differents resolutions without problems, in a wide desktop in dual display mode. HELP!
