I'd like to post an update and a question.

I've got a Dell Dimension 9100 Intel Pentium 4, with a 3.2 GH processor and 3 GB of Ram. I've got an Nvidia GeForce 7600 GS video card.

But whenever I hooked up this computer to the Apple 30inch display I could not get my resolution above 1280x800

When i hooked the computer up to the 23inch Cinema Display i had no problem maximizing the resolution to 1920x.

THe problem is only on the 30inch. I heard that the Nvidia GeForce 7600GS has one single and one dual DVI slot, and only the dual will allow a full 2560x resolution on the 30 Inch display.

But switching the display plug from one slot to the other didn't help the matter, I still cannot raise the resolution past 1280x800

Can anyone please help? is it just impossible to get max resolution on a 30inch Apple Cinema display if you're not running an Apple pc?

Moved to better location.

I am using the Apple 30" HD Cinema Display right now on my Dell workstation. I have the Nvidia Quadro FX 4500 video card. (Brand new computer, for those of you following my Alienware/Dell woes). My previous computer had a Geforce FX 5900 SE video card which couldn't even get this monitor to display anything. Therefore, I was using this monitor with my G5 mac until I was able to get this new Dell which is capable of running it.
