I have created a custom resolution from Nvidia CP; 1920x1080 at 75 HZ.
native is 1920x1080 at 60 HZ.(Black screen above 75 hz)
The problem is when I apply the settings, the display gets stretched? and goes out of the screen. I have a Samsung SyncMaster S22B150, nothing fancy. When I use the auto configure next to the power button it just makes a few attempts and comes back to the same state. I cant seem to find any option to resize my screen. Any help would be apreciated. I know I should have taken it to Nvidia forums but that place is just dead and totally unprofessional people 'try' to help you, so just decided to come here.

Looks like you are unable to overclock that display much. Like any OC it's a bit of a lottery, tbh though I have both 75Hz and 60Hz displays, you can barely tell the difference between the two.
