I had the same problem with DVI. I tried all kinds of things to fix it for the last week nothing worked. Came across this thread last night and tried DVI recovery disk. This fixed my DVI problems. I want to thank you for the help.
I bought this monitor last week at buy.com. I have not been able to get the DVI to work. I've tried both nvidia 6800 and nvidia quadro 4. Is anybody else having problems getting the DVI to work?
