A couple of stuck or dead pixels are expected on any LCD. However, if they're especially bothersome, say, in the middle of the screen, you should argue your way to a new unit, especially if it's still under warranty.

Two misbehaving pixels isn't bad for a 19-inch monitor, though, and you could very well exchange it only to receive a monitor with more than two pixel defects. Though if you're intolerant of any dead or stuck pixels, I suggest that you buy from a company such as Philips, which offers a no-dead-pixel guarantee.

Also, if you're the risk-taking type, you can try massaging stuck pixels back to life. Simply wrap your finger in a soft cloth (not a paper towel) and very gently rub your finger over the offending pixel for a few seconds. While doing this, it helps to have a movie or color changes on the screen to stimulate the pixel. But be careful if you choose to do this: pressing too hard could cause more damage.
