I've been using this LCD monitor for a long time now. A few days ago a thick horizontal line appeared at about the height of the browser toolbar, about 150px from the top of the screen. It has an uneven width, at its widest it's about 20px and it kind of fades in and out along the line. This area is consistently a good bit brighter than the surrounding area, even at maximum screen brightness & contrast

I tried to get rid of it by leaving the PC on overnight with a white picture as screensaver but can't really say if it's gotten better or worse

Any ideas how to fix it?
