Hello all, my old monitor died on me so I sent it back to ASUS and they ended up sending me a new VG27AH (monitor) for free. I have seen a lot of people posting guides on how to get 1920x1080p with 75hz. Unfortunately, all the guides and things I found were for Nvidia Control Panel and people with those cards. I have an HD5850 and could not make any custom refresh rates in their CCC tool.
Whenever I select 75hz in any display option screen it grays out all 1080p resolutions. If anyone knows how I can get 75hz on my new monitor any help would be greatly appreciated.
Edit: I forgot to mention in case anyone was wondering this monitor is in fact 3D but does not support 120hz. It's maximum refresh rate is 75hz.
