How common are stuck or dead pixels on the MacBook Pro? I purchased a new Macbook Pro (15.4" with 500GB HDD), and discovered it had a stuck pixel in the centre of the screen. This pixel was always lit green, and any attempts to resolve it myself didn't work. I took it back to the retailer, who happily exchanged it for another one (which had to be ordered). I picked up the replacement yesterday, and to my horror, its screen had the same problem, although this time the pixel was stuck on red, and was in the bottom left hand corner of the screen. Another replacement has been ordered, and I'm now a little concerned that this may have the same problem.

This obviously has me pondering the quality of the latest range of Macbook Pro laptops, and I'm wondering how many of you may have had the same problems with your ones. Please share if you've had a similar issue.
I've had a number of Mac laptops, starting with a PowerBook 100 way back in the dark ages. I've been fortunate, I guess, that I've never had a stuck pixel.

You're fortunate that your retailer is working with you, as Apple considers a single stuck pixel to be within acceptable limits. That is, they don't promise zero stuck or dead pixels, so generally you'd just be out of luck. [Worth noting: ISO 13406-2, the standard for flat panel displays (more analysis here)].

If you find this happening again, though, you might try one or more of the (non-Windows) suggestions at How to Fix a Stuck Pixel on an LCD Monitor.
