if you can't stand the pixel problem. As you say, once you know the dead pixels are there your eye is constantly drawn to them, and you'll never feel relaxed when using the computer.
Sometimes it's possible to turn dead pixels on by gently massaging them with a slightly moist cotton bud. Rub the cotton bud over the pixel in a circular motion and see what happens. Don't overdo it, and if it doesn't work first time, give up and start repacking the machine.
