Dead pixel or not?

If just the red and green subpixels are dead, it will be invisible on black and red backgrounds. If you want to replace it and Apple gives you trouble, you might be able to claim that it is 2 pixels because 2 subpixels are dead. It is very unlikely that you will get more since most dead pixels come from the factory. It is possible for a monitor to develop stuck or dead pixels later in life, but that probably won't happen until the warranty is out, or until you hit the screen with a sharp object.

If you have a good magnifying glass or a cheap (toy) microscope, try to see exactly which subpixels are dead. Post a picture if you can.

 

You can try a stuck pixel fixer. They are basically rapidly flashing colors to try to unstick the pixel. Leave it running and don't let the screen go off for at least 24 hours (though it will probaly take more time). It's worth a shot even though I've never seen one actually fix a pixel.

 

I completely agree. Try the fixer on this website. It's free.

 

I thought they would only replace it if you had 4+ dead pixels. Congratulations and lets hope the next one is perfect

 

I bought a 19" Samsung flatscreen when I was in highschool (things were expensive at the time!) that developed one dead pixel (might have been there when I bought it - who knows).

Someone recommended that I rub a finger over the pixel (with a little pressure - not enough to damage the screen obviously). I though it sounded like a load of crap, but it actually managed to unstick the pixel. It got stuck once or twice again later, but every time this brought it right back. Side note: this might not be possible on the macbook, seems the newer ones have something covering the screen...
