so who is good with computers i am running dual 7900 GS graphics cards and setting up my tri-screen setup. the first two as a horizontal span work fine but the 3rd, as a single setup off the the right is givin me trouble. it is all messed up looking and keeps telling me to change the resolution to 1440 by 900. but it is set to that right now and nothing shows up except a bunch of blurred lines. when i change the resolution the screen will work but it will be crappy quality or too big for the screen so it shifts with the mouse. IT DID WORK UNTIL I TOOK A SCREEN TO FIX A FRIENDS COMPUTER SO ITS POSSIBE sorry if this is the wrong spot.
