My monitor's display supports upto 170Hz but changing from 60Hz to 75hz is fine if i go a little higher like 85hz the display stops working. It says Generic PnP Monitor and its a Dell monitor and also the display i use is 1280 x 1024 and says that supports upto 2560 x 1600 but if i go higher than the current display i use the display goes off/ or it says connot display this video mode
