Yes. What grafix card are you using. If you are using onboard, or a cheaper (less expensive)grafix card it will NOT always support a resolution of over 1024 by 768. Normally the higher end video cards like the 6800Ultra I have supports over 1680 res. So check you grafics card. That should be the fix to the problem. Not 100% on it since i cant physically see the monitor and setup you have.
