Test screens for bad pixels detection on macbook pro

[paulchiu]

you could use a white background to look for dead pixels, which usually show as a black dot.

to find stuck pixels, where only one of the color sub-pixels have turned bad (i.e. red, green, blue), you'll need other solid color backgrounds.

i have here solid backgrounds for red:

open up safari with your new macbook pros and macbooks, open each of the above links and scan the screen from top to bottom.
be methodical.
just getting a perfect white or black background display may not mean a perfect screen unfortunately. testing for red, green and blue will almost assure you that your 1920x1200 mbp-17 is picture perfect, in terms of pixels.

i used this method last spring when i bought a macbook air. found a stuck pixel on a red screen and only a red screen. since it was under 2 weeks, my apple store took mine back and gave me a new one. luckily, that one passed the pixel test.

good luck on yours!

If one of your 2,304,000 pixels doesn't want to turn blue, it's ok.

true if it were just one.
if you get a cluster of 4, that's another story.
