I've got an older Gateway gaming machine running Vista Home Premium with an ATI Radeon HD 2400 XT video card, 3 GB RAM and a terabyte of disk. Display is an Acer LCD with specs indicating it will operate up to 1600 x resolution. Everything was working fine until I was poking around in the ATI Catalyst Center looking at the video card settings and noticed a resolution setting I did not remember seeing before - 1900 x - without thinking I clicked on it and immediately regretted it! Instead of getting a question whether I wanted to keep the resolution setting the display freaked out and went dark. I'm thinking I set the video card resolution setting beyond the capabilities of the display and am now suffering the consequences. I can only use the system in safe mode now - if I allow the system to boot in normal mode the display goes back to the dark screen which 'twitches'. I tried 'last know good configuration' to no avail. This particular machine does not have a recovery point so that will not help. I am holding off removing/reinstalling drivers in the hope I can fix this in some other way while in safe mode - maybe a registry setting change?
Any suggestions are appreciated!
