I have set the screen res too high and get a warning input signal out of range in the middle of a black screen. Compaq deskpro.How do you switch it back?
Right click desktop > properties > settings > then you should see Scree Resolution.
Typo! Scree should be screen!
Thanks Beta. That did the stuff phew :-)
If you can get hold of a higher resolution monitor you could use that while you change the resolution back.
