There is a program, alas I do not know its name....to test colors, put up a full screen of a dark green, a dark red, and a dark blue. Dead pixels will rear ther ugly heads for those colors.
For ghosting, try a game like need for speed, that has a lot of fast movement and would easily show ghosting. That, or just go into any FPS and spin around really fast...that'll show ghosting as well.
