I just returned my iPad 3 to the Apple Store. The reason? A pinkish/rosy white balance, very noticeable in strong natural light but admittedly much less obvious in artificial lighting and/or dark rooms.
This was the second iPad 3 I've had. The first had an even worse tint, and I returned it almost immediately.
I know some of you are itching to hit that Reply button and throw insults my way. Don't bother. I know that I'm fussy. I'm not obsessive, though, and did try to live with the problem for the 14 day period. I just couldn't. When I removed the Smart Cover and saw the pinkish white squares into which I had to type my lock code... It drove me mad.
I've been using TFT screens since they were first introduced -- back when a 15in panel cost thousands of dollars. As a journalist I used to review them for magazines. The problem was always that whites are very stark white, if not blueish. Think about when you first used a flat panel screen -- it was really noticeable compared to a CRT.
There's a theory our eyes are now trained to see blueish white as pure white, thanks to colour profiles on domestic TVs. This might be true, but I promise you with my hand on my heart that my iPad had a genuine pinkish/rosy white balance. I could spot it, but then I'm an expert. Most people aren't.
I got a refund, and now I'm waiting a month or two. I will get one eventually (I'm commissioned to write a book about them, so I have to!). The one I get might be the same, or better. My plan is to buy five of them on my credit card, then choose the best one out of them, before returning the other four for a refund. This is a crazy thing to do but I can't see how I have much choice.
Did you take the time to talk to the Geniuses about the problem? I mean they see literally hundreds of screens so they know good from a bad one. You sound like you've been tortured for 14 days by your screen. My first was was a bit pink so I just took it back to Apple, compared mine to the others they had on display. They said mine was faulty and did an instant replacement with a new one. It was much better, the greys looked grey. It still has an ever so slight warmer tone but I can tell you in photos, skin tones took totally supreme with none of the bluish hues on so called 'perfect' white screens. I also think mine has become a little whiter still over the last week (could just be my eyes). the iPad is first and foremost a luxury 'feel good' deviceso if you're not happy fair enough, return it. My advice to anyone not happy with their devices is to go and talk to Apple.
