Apple Cinema HD 30 software update
Why I am not getting full 2560X1600 resolution from Apple Cinema HD 30" Display hooked up with Power Mac G5 Dual 2.7 ?
And how can I fix this problem?
It depends on the graphics card. You need dual-link DVI. Some cards have only single-link, some have one single-link and one dual-link. Some have two dual-link ports. If your card has two DVI ports, try the other one for the 30" display.
