How can you tell if your monitor has dead pixels?

Dead pixels only apply to LCD monitors and are easy to detect.
An image editing application works best in full screen mode. Display an image which is a solid light grey and look for individual dark pixels. If you use a very bright white, some dead pixels may not be noticed.
You will also want to check for STUCK pixels. These can be detected with a dark grey or black solid image. They mey be stuck in red, green, blue or in combinations of these colors.

Dead pixels do not only apply to LCDs. I've got an old CRT monitor with one dead pixel where the shadow mask wasn't cut out properly.
A quick test for dead and stuck pixels is to first display a completely black screen and look for non-black pixels, then display a completely white screen and look for non-white pixels. Since yellow pixels might be hard to spot against a white background, you can find any by displaying a blue screen and looking for any black pixels.
