Help please please please anyone, my kids have been bashing buttons on my laptop and now i'm left with a screen thats like this :
Imagine my screen is say 20 by 20
my main desktop has sort of been squeezed into 15 by 18
then the screen repeats itself so i've got a duplicate start of a screen on the right handside plus a small duplicate bit running across the middle.
Screen Resoltion adjustment just alters the text e,t,c but doesn't get rid of this duplicate problem.
