Hello,

I have an Old "Dell IN1930" Which I tried to OC to 75hz, The problem is when I do the overclocking the screen goes dark for a second then shows up again telling me if I want to save the change, but the display is messed up, its pushed to the left beyond the screen borders and the quality is bad (pixalated and not clear).

I heard that if your monitor doesn't accept the OC it will go dark for a longer time then reverts automatically to the default refresh-rate, but in my case it didn't, So what is the problem?

P.S i am using a VGA-HDMI adapter (Maybe it's the reason?)
