That sounds very bad. One more test please. Go get any LiveCD of any current Linux like Ubuntu. Does the display work ok in Ubuntu?
I have a 1 year-old HP laptop, model dv8408us, windows XP media center edition, Intel Centrino duo processor, nvidia geforce go 7600, and after an automatic windows update, the display started this unusual behavior. I had no anwser from microsoft, undid the windows update and nothing happened, then updated again. HP told me to update drivers and bios, which I did, but everything stayed the same. You see, the white background on every window looks cyan, but not all of it, the black background has like these flickering red dots on the edges, almost like a shadow, and for example c|net's banner on the top of this page should be yellow, right? well, it has these flickering cyan horizontal stripes. What intigues me the most is that these defects on display move while scrolling the screen up and down, and i even tried an external monitor, which displayed no problem at all. Anyway, even the first windows logo when booting or the menu when pressing f8 to boot in safe mode has a red flickering shadow to it. Is it a fisical problem or rather an adjusting/driver/card problem? Can I do something to get rid of this annoying thing?
