So , I was messing around with my monitor hz lately and God knows why, but i changed the screen refresh rate to 120 hz and all off the sudden the screen got blacked out and *** :|
Tried restarting/shutting down the computer , but every tme it shows there isa message of screen saying " Opitmal Mode 1920x1080 60hz.

I am freaking the *** out, is there any way i can change it, like by the boot menu D:
I am current using the safe mode :|
