Does anyone know what the Apple warranty is on dead pixels in their LCD panel line? I have a 15" Apple LCD display that arrived with one dead pixel, approximately dead center, that shows up red.

I'm assuming that Apple considers this dead pixel in the center of my screen to be within fault tolerances for these devices. If not, someone please let me know, as I would like to have the display repaired while it is still in warranty.

from Apple Knowledge Base article# 22194, discussing "pixel anomalies"

[quote[A pixel stuck either on or off is known as a pixel anomaly. A small number of pixel anomalies is acceptable. An active matrix color LCD panel contains three sub-pixels (red, green, blue) to generate one pixel on the display. Therefore, there can be over 2.3 million sub-pixels on a higher resolution LCD panel. Each subpixel has a corresponding transistor that is responsible for turning that subpixel on or off. A faulty transistor results in a subpixel anomaly. Of 2.3 million transistors, having a single or a few bad transistors is certainly possible.

Due to current manufacturing methods, a certain number of subpixel anomalies (a pixel stuck on or off) is considered acceptable. Because the manufacturing yield of perfect active matrix panels is very low, displays may have some subpixels that are either always on or always off. The cost of accepting only perfect displays could nearly double the price of a product using an LCD display. This is true of all computer products using LCD technology, not just Apple products.

If you suspect your display contains a high number of pixel anomalies, call Apple technical support, or take your Apple product to an Apple Authorized Service Provider for closer examination.

so yeah, with only a single stuck pixel, you're supposed to consider yourself fairly lucky.

Thanks. That's what I thought, but was wondering if the policy might be any different for desktop displays than laptop displays.

I'll consider myself lucky. I certainly have no complaints about my Studio Display.
