My video card allows me to "override monitor manifacturer's refresh rate (at your own risk)". It's a 6MB 3dfx Rush Adrenaline and my monitor is a (3 years old) 17" proview. The thing is that I want to be use a 1024X768 resolution and because either the card or the screen is too old, I have to override the refresh rate to 70hz to get an stable view. Proview say that my screen is 56-60hz capable. Son here is (finaly!) my question: will it really damage anything ?
