My monitor is no spring chicken, but its worked perfect up until about a day ago. It is an LCD, the Dell E207WFP, about three years old. All of a sudden I am recognizing on dark backgrounds diagonal waves all on my LCD display. I thought my video card went bad or it was a driver problem, so I updated it. Still the same thing. I plugged the VGA into the standard on-board and still waves. I removed all magnets and speakers, and STILL waves! Its so annoying please give me any tips, oh and I am running windows 7. Should I jump for a new monitor? 🙁
