I have an AMD GPU, a XFX R9 280X, that is connected by a Dual Link DVI to my ACER GN246HL. The GN246HL is rated to work up to 144 hz and when connected to my buddies Nvidia computer, it works up to these refresh rates with no problem. However, it will not go beyond 60 hz through windows, AMD Catalyst Control Center, ToastyX CRU, or any other method that I can find. I have tried different DVI Cables, and also tried the last 3 AMD Drivers, which did not work. I am perplexed and can't figure out why the DVI is not working. Sadly, the monitor does not support Displayport, so I am trying to find a why to have the monitor work through DVI. Please let me know what is needed to get this issue fixed.

If your video card has two DVI ports, then you're using the wrong DVI port. R9 280X cards with two DVI ports have one dual-link DVI port and one single-link DVI port.

The patch will allow 120 Hz to work on a single-link DVI port (and 144 Hz with the 1.3.1 patch), but the monitor might not be able to handle higher refresh rates with a single-link DVI connection. You shouldn't need the patch with a dual-link DVI port.
