An internal document at Apple has been released, which states that the larger the display on your Apple device, the more dead pixels you’ll require for Apple to authorise a replacement.
An internal source leaked the document to BGR, which is a guideline for Mac Geniuses in Apple Stores in order to determine whether or not a customer’s display requires a repair or a replacement.
The document shows a table, showing the number of dead pixels required to start this process. This is determined by the size of the screen.
iPhones and iPods only require one pixel anomaly to get a repair or replacement.
MacBook Air models need to have more than four light pixels, more than six dark pixels or more than eight combined anomalies before they can get a repair or replacement.
For a 27-inch iMac, Apple considers up to 15 combination anomalies to be acceptable, with displays requiring 16 or more to qualify for a replacement.
Apple’s support page states that if the customer suspects their display has “a high number” of pixel anomalies, they can take it to an Apple authorised service provider for closer examination.
