So I have a gtx 760, and a BenQ gl2450 and I tried to 'overclock' my monitor in the NVIDIA control panel using G-sync, which went fine, I overclocked to 75hz from 60 and it said test successful and everything in the 'create custom resolution' tab but when i go back to the change resolution and try to change my resolution from there 75Hz does not show.... any help?
EDIT: also in games it does not give me 75hz option
