I have XP Home Office...and I had a very dark screen for some reason so I tried to brighten it. I did this by upping my contrast and my brightness on my monitor, no luck. I thought that maybe I would change the pixels and that might make a difference. I did this in the display settings and promptly got Error message : Input signals overrange ..etc, garbled snowy screen. I have tried upteen times to fix this problem on my own and followed ms directions carefully per their website which was less than helpful. The xp defaults are a little different and I tried them all, I think anyway with no success. Please help!
