From Monoprice on the warranty: "we are guaranteeing these monitor will have less than 5 dead pixels. [...] By comparison, the industry standard, even for industry leaders like Apple and LG, is 10 dead pixels or even more."
Is this true? None of my Apple devices have ever had a dead pixel, but I always assumed that even one dead pixel would be enough to convince the Genius Bar to give me a replacement. Anyone have first-hand experience with dead pixel warranty replacement on Apple devices?
They're probably all LG panels under the hood[1]. Different resellers have different pixel policies, and they can be a bit hard to keep track of.
On these size screens, Apple won't replace <11 dark (dead-looking) or <9 light (stuck-looking) pixels. HP's policy is about half that. Lenovo is like 4 or something. Some of the other manufacturers have even more complex policies which depend on the position of the stuck/dead pixel.
And in practice, if you complain well enough in the store, Apple may replace for you even if you're under the line.
[1] When I say "they", I mean these 27" IPS panels, whether they're from Apple, Dell, HP, or some random Korean company.
The problem with Dells return policy - at least according to much i've read about it on the interwebs - is that they indeed have a pretty liberal policy regarding returns, but you seem to be almost guaranteed to receive an already returned (i.e. not new) display...
I've found this out because i wanted to swap out my U2711 which has some issues when it's warm in the room - it might just go blank for a few seconds and then go back on again...
However since that is quite seldom (sometimes once a week, sometimes 3-4 times in an hour and then returns to normal) i've refrained from returning it cause one could get an even worse model - or so i've read..
For what it's worth, Apple replaced my Retina iPad that had a single stuck pixel, and it was only noticeable on a dark background in a dark room. While it's a small screen, the number of pixels is about the same as on the 27" Cinema display.
What their official policies say and what they actually do are pretty different, it seems.
I never had issues with an Apple big screen but they replaced my 13" MBA for a single dead pixel. And the Apple Genius was very surprised as he never saw faults on those.
For months, people who know what’s up have been buying Cheap Korean 27-inch monitors because they’re made from the same panels as high end monitors. But for a third of the cost. Monoprice is selling 2560×1440 IPS monitors for $390, in that same spirit. They use the same LG panels as the 27-inch iMac (except Apple only takes the best; these are the rest), but Monoprice is offering a 3 year warranty and they check every panel for dead pixels–most Korean monitors, which are imported or sold on ebay, don’t do that.
