motion blur != ghosting (Score 0, Informative)

Come on people, get the terminology right. Ghosting and motion blur are not the same thing!

Ghosting is when you get a faint duplicate of the entire on-screen image, slightly offset from what it should be. I don't think this can even occur on LCDs, I think it is a CRT-only problem, but if you use crappy analogue VGA cables, then who knows?

Motion blur is what you thing ghosting is. It is caused by poor refresh times, more specifically it is caused the amount of time it takes for a pixel to become unlit, or "switch off". So LCD screens that have a poor response time often show a trail after a moving object that looks like a ghost of the object.

Understandable that you could get the two confused, but still wrong. /mike
