One of my screens seems to be overheated, just like a car with a bad radiator. For the first few hours of the day everything works as usual. Then about ten o'clock the monitor starts making this faint humming sound. After about five minutes it goes black screen. The power doesn't turn off but the monitor loses the picture. If I turn the monitor off for a few minutes and turn it back on, the monitor will last for only a few seconds. This has happened the past three days. I tried switching monitors and the new monitor works find on the PC where this problem originally happened. Has anyone else had this problem? It looks like a hardware problem within the monitor. I don't think this thing has a warranty. I bet I'm gonna have to lay out some cash for a new one.
