Actually you do ! .. Thanks for one program (I dont remember its name, i will post it when i got home) I can use 75hz on my LCD, if I hadn't used it I couldn't have got them .. In others words i forced 75hz .. Theoretically my LCD doesn't support more than 60hz .. But it seems it does :P ..
Why? No risks involved. Reforce simply scans your monitor and displays the highest refresh rate you can achieve at a given resolution. Very useful. Don't be scared just because it is an .exe :p
