RE: Display - Variable help quality from DeLL - Screen Distortion - Dell will help, sometimes.
What is the glitch? I find that occaisionally the Sceen display goes unusual. It is set to 120% in Advanced Settings of Desktop properties. This may be stable for months, but then corrupts. I have not found the source of the corruption, but can correct for the time with System Restore. No "Reinstall the OS" is a cop-out! I would like to handle the source if possible.
