I have overclocked the panel to 75hz,I have created 2 different custom resolutions,the one is 2560x1080x75 and the other is 1920x1080x75.
The default refresh rate is 60hz.
The problem is that when i click on the custom resolution on nvidia control panel and apply the setting,it keeps reverting back.Even when I set it to 1920x1080x75 it resets back to 2560x1080x60.
I have used blur busters UFO tool to check the refresh rate,which validates what I am saying.

Also,the monitor has no DVI port for me to use,only HDMI and DP.I'm using HDMI at the moment and my GPU does not have a DP input.
