I am still unable to solve this. I have tried the Custom Resolutions Utility:
But the resolution is still not showing up as an option.
I tried directly adding the resolution to the registry as described here also:
But still no luck.
Okay, so I figured out the card I have here:
Has the highest output resolution via DVI at DVI Max Resolution : 2560x1600.
I tried hooking up a dual link DVI cord, but now my BIOS and Windows start up logos have green lines all over them and Windows won't display once loaded. My monitor (PA279) just says "Out of Range" on the DVI settings.
What the hell am I supposed to do here??
