hello! i have a msi gf63 thi 9rcx laptop wich has a 60hz monitor,so i decided to use CRU to overclock my monitor to 75hz,after i applied the new refresh rate from my display settings i had no screen glitches (sometimes i can see a white line at the top of my screen but no so often),i can feel te diffrence between 60hz and 75hz so i kindda want to keep iit.my question is:is it safe to use? can my screen stop working after some time?can it blow up? what can happen after some time?
