Da questo articolo OS X Daily , il morto ufficiale / politica dei pixel bloccati (dal 2010) è:
Apple’s Dead & Stuck Pixel Policy
Here’s the breakdown from the leaked Genius chart:
- iPod nano, iPod touch, and iPhone screens: repair or replace after 1 or more dead pixels
- iPad: repair or replace after 3 or more dead pixels
- MacBook, MacBook Air, MacBook Pro 13″ and 15″ models: replace after 4 or more bright pixels, 6 or more dark pixels
- MacBook Pro 17″, displays up to 20″: replace after 5 or more bright pixels, 7 or more dark pixels
- iMac 24″ and iMac 27″, Apple Cinema Displays from 22″ to 30″: replace after 9 or more bright pixels, 11 or more dark pixels
Tuttavia, l'articolo suggerisce anche che il trattamento nel mondo reale può essere molto diverso:
Apple’s Official Dead Pixel Policy vs Real World Experience
While the official guidelines for handling dead pixels seem strict, I
suspect there is a larger policy at the Apple Store for ensuring
customer satisfaction. Speaking from direct experience, Apple can be
far more generous than this support document suggests. Case in point;
I purchased a MacBook Pro 13″ earlier in the year and discovered a
single dead pixel glowing bright red smack in the center of the
screen, you couldn’t miss it. I took the Mac back to the Apple Store
and an Apple Genius swapped the machine out immediately, saying he
wanted to be sure I was happy with my purchase. The new MacBook Pro’s
screen was flawless, and yes, I was happy.
My advice to anyone who is dissatisfied with either a dead or stuck
pixel is to talk to Apple, at the end of the day customer service
seems to always win out over official policy.
La cosa migliore da fare è portare la macchina da controllare - è molto probabile che l'Apple Genius con cui stai lavorando faccia del suo meglio per renderti un cliente felice.
