Smell the monitor, if if stinks you have dead Pixies......oh wait you said Pixels. What makes you think you have a problem? Might try setting your desktop color to white and see if you have a problem.

yup if you set your background to white then if some are not lighted as they should be then you have dead pixels

Set the desktop to a white background and look around for any non white dots. Also, change your background to black to look for any other oddities, since LCD's can have completly dead pixels, a pixel with no red/green/blue, or a pixel that leaks the backlight badly.

Bad pixels are often invisible with a white screen because usually only one primary color of a pixel goes bad. So it's much, much easier to see these defects by painting the screen all red, green, or blue, one color at a time. Also bad pixels aren't always dark but are sometimes the wrong color or even white, the latter being so with an old TV of mine, and I don't notice anything unless that area of the screen becomes all blue.

Try an off or pastel color, those usually show them up.
