From the research I have done I should be able to hit 2560x1600 with this equipment. But, it maxes at 1280x800. I have tried using the old ATI Radeon HD 3400 with a Dual Link DVI cable. I switched to the DisplayPort using a Display to DVI with the dual link cable but still hit 1280x800. Remove/deleted drivers and installed but no luck. Both devices spec to 2560x1600. I have a newer 24" Dell monitor that I connect to and it can hit the 1900 res.
Any ideas?
