Custom Resolution Utility (CRU)

[Wilk Freeman]

Decided I'd jump in and try to edit my monitor's resolution without knowing the first thing about it. I have a few questions if anyone wouldn't mind answering them that'd be great.

I'm using a DELL U3011 with an R9 200 Series GPU driver 14.03 and I've applied the Pixel Clock Patcher.

I found my monitor used a Dual-Link DVI and from what I read I should be able to use custom resolutions that use a 330MHz or less pixel clock. The default max resolution uses 268.50 MHz. But when I try any resolution over 2560x1600 I just get the message "The current input timing is not supported by the monitor display."

I've tried all different combinations of resolutions but it will not display above 1600p, why?
