Dead Pixel = White on black screen
Red dot = stuck pixel (you better with with Dell what is their policy on that, Samsung have a 1:1 exchange for a single red dot within 7 days).

Correct me if I'm wrong, you cant see the red dot under black page cause, to display black, all the pixel is on "ON" position. Hence any stuck pixel doesnt show up. Black screen test is to look for "Dead" pixle which will show up white.

Pls dont rub the area etc etc... it doesnt work. You migth come worse off and leave mark on the LCD screen...

Dead Pixel : Well, when the transistors of a pixel is dead, the result would be a white dot as lights would not be blocked from passing thru the RGB? Isnt this what we refer to as "Dead" pixel?

Such "stuck" fixing method generally doesnt work. And even when it does (sure there are claims it worked) most commented that the problem comes back. Also, the LCD is made of plastic, although it is coated with an anti-glare coating and is somewhat scratch resistance to a good degree. This surface is not however scratch proof. Even rubbing using a piece of cloth might produce abrasion on the screen.

The monitor in question is an UltraSharp series (?) Their replacement for that is ONE bright dots (or more ofcourse) or 6 dark dots. My advice would be to leave it in perfect order while asking for a new unit, why risk leaving physical deformities when you want to claim Dell??
