Re: lap top screen res problem
Hmmm, I have no clue. This is a complex problem. Nonetheless, the answer may very well be to:
Download and reinstall display driver
In this case, I'd go to support.dell.com and search for your specific laptop model (the Inspiron 1520). Download the latest BIOS update and latest Nvidia driver. If you do not know how to flash a BIOS, Dell provides instructions at the download site.
*Fact: Microsoft Window's Blue Screen of Death vs Computerforums.org's White Screen of Death. Which is worse?
