This same problem that was posted over a year ago:
http://www.computerhope.com/issues/ch000191.htmhttp://www.computerhope.com/forum/index.php?topic=37755.0PLEASE READ LINKS ABOVE - I AM HAVING THE SAME EXACT PROBLEM BUT THE SOLUTIONS GIVEN ARE NOT WORKING.
I have a DELL Dimension 4600.
Its is 4 years old and I have never had this problem before but I haven't used this computer in over a year.
The monitor has been used with 2 other computers and functions fine.
NOTHING HAS CHANGED ON THIS COMPUTER EXCEPT the same OS (XP) from the factory was reinstalled. ALL hardware and software is exactly the same as what orginally came with the computer and functioned properly for 4 years.
The other day I broke it out and reinstalled the OS.
Ever since then I am having this problem, the screen resolution is completely wonked!
I have already tried to change all the display settings AND every CD that came with the computer AND I downloaded BIOS drivers from the Dell website.
I have tried EVERYTHING, every suggestion that I can find and nothing makes any difference. I even ended up having to reinstall the OS AGAIN because I screwed it up trying to fix this problem.
I can't install my printer either (because of the screen resolution). This is such a stupid problem and its totally frustrating!
Please help!
