I have a phillips 107s, and its just started doing this to me aswell, only young people can hear it lol. 2ys ive had it, had a 3 yr warrenty on it so i better get onto that. Also with my monitor, i have to have my brightness and contrast on 100% to make everything actually look normal now, because if i reset defaults like it used to be, everything appears really dark, games especially you cant even make out the walls.
Now im sure my monitor is on its last legs and all, but for my next one who thinks that some pretty large sterio speakers sitting within a foot of the monitor would do it damage? A bigger table on the cards you think? Also would carting the monitor around in a car a fair bit do any harm.
