Artifacts on LCD monitor

burn-indisplaylcd

I have an LCD monitor which was, arguably, relatively cheap. Undoubtedly it's due to cheap manufacturing, but after a while of continuous use, I start to see artifacts of previous images (resembling CRT burn-in). I've also noticed the these areas of the screen tend to get a bit toastier than unaffected areas.

Turning off the monitor for a while does return it to normal, so it's not a permanent problem, but it is rather ugly when it happens. A Google search resulted in no more than "this happens sometimes". Does anyone else have experience with this?

  1. Anyone know the cause of this? (Feel free to get as technical as you'd like.)

  2. Aside from the obvious of trying to exercise the pixels as much as possible when in use (i.e. don't leave SO/SF/SU in a browser open all day), is there anything I can do to reduce this? Would improving cooling help or is it not heat-related?

I don't think it's cable or video card related at all. It's usually the top left corner, and artifacts of things that don't change regularly (the desktop, browser toolbar, etc) are still visible when I change what is shown there (usually by switching to another application). Like I said, it looks like CRT burn-in. When the monitor is off for a while and is turned back on, however, the problem goes away.

Best Answer

It could very well be the cables, but where are the artifacts located on the screen? That is a huge determinant. The edges of a screen are generally warmer and so it may not be a related symptom.

But that aside, the answer you're looking for has many possibilities. My belief is simply that you have dying/near dead pixels.
