I just got a Samsung 305T hooked up to a pair of PNY GeForce 7900GS running on SLI with a dual-dvi cable. Strangely, I can run at native 2560x1600 but when I switch to 1280x800, a quarter of the screen is duplicated on the left (I posted a screen capture at http://www.xephalon.net/stuff/double.jpg). Any idea how to fix this? I'm running an Athlon 64 X2 4600+ on nForce 590 SLI, with Windows XP SP3 and Nvidia GeForce driver 190.38 (most updated). I need to run my games at 1280x800 or it lags like crazy... Hope you guys can help!
The picture shows the double image on the right (you can see 2 system trays and 2 recycle bins) and some vertical static lines about a quarter the way from the rigth of the screen.
I've tried to turn off SLI but no change. I tried to just take a screenshot, but the screen shot actually makes it look completely normal. Again, this problem only happens at 1280x800, but 2560x1600 works fine (luckily).
