Q: MacBook Pro Retina display burn-in?

Shay: So far I'd agree. I did some earlier IR tests people suggested just the average everyday ones. Got a zebra stripes pattern (had a light coloured background) and left it on screen full brightness for 10 minutes as I'd heard people say after 5 mins or less they'd seen noticeable IR and they weren't really pushing.

I didn't see a thing. Ran it for longer (20 mins) still nothing. And I played games on full blast contract (colourful ones like Civilization 5).

And i figured you'd see IR really easy on the Mac login grey screen etc but never saw anything and I'm not exactly careful. I'll walk away and leave my computer screen on for 15 minutes until it shuts itself off naturally

Never saw a single hint of IR. I was **** happy. But I cam across this new test and I though hey why not I'm almost finished with my 14 days one more test can't hurt.
Ran the test and yeah I can see the checkerboard pattern pretty clear but only on that one particular background.

So yeah its there but at the same time its because I went looking for it in a deliberate and very "manufactured" way. Not shying away I wish it didn't have this because once its in my head then I can't really pretend I didn't see it.

But lets also be take logic the other way yeah? I would never have noticed this if I had not deliberately gone about trying to make it happen.

Some might say well now you know and you know its an LG panel its colours are off. I just did a claibration and all that. My white point is 6509 and its already **** perfect. No colour off's etc.

Yes its poissible because its an LG panel it might F up in the future but that would have happened anyways if I didn't notice this little issue anyways....

How did you do the calibration?

Can you walk me through?

Thanks.

Select LCD COlour and click Calibrate

You mgiht notice a lot like on mine that you actually don't even need to calibrate it as its already pretty perfect.

Well if that's all you did then it is the exact same calibration as the calibration of the screen right out of the box. You basically didnt change a thing. When you compare that calibration to a Samsung's right out of the box, Samusung's whites are still better.

Okay, thanks. I hope maybe the later builds might solve the problem, but that's probably being really optimistic. I think I might order online instead of getting one from an Apple store because then they just start building it to order, versus getting one that was built and shipped to the store a week ago. What build week are they making now?

I was under the impression 65000 or higher white point was exactly where it should be?

What other programs calibrate this stuff? Be more than happy to give it a go. And if you have a Sammy whats the white point for you?

Actually just changed my white point to 8000 rather than 6500. 6500 seemed a bit yellow upon comparing the two.

Also is there any issues with having it adjusted to 8000? Does it wear out the display quicker or have any adverse effects? I mean it would seem to me if I can adjust it to 8000 then it can handle it...?

Supposedly, all rMBPs are preset to the same white point and Kelvin temp. The Samsung's preset, however, is much more faithful to that actual measurement (when compared to the warm LGs). In other words, 65k Kelvin looks a lot whiter on the Samsungs and good LG screens, than it does on the yellow LG screens (even though they all say they're set to 65k Kelvin). Even if you could compensate a warm LG by calibrating it to a gamut and white point that appear whiter, your screen won't display colors as well as a naturally unproblematic screen (displaying at a non-native white point is generally deleterious towards other color representations. You can witness this by setting your white point to warm and cool in System Preferences. Your screen will turn orange and blue, respectively, and other colors will look washed out). You might also find that, on a dim LG screen, the highest brightness setting is only equatable to a lower brightness setting on a good LG/Samsung. This is significant in that, at the highest brightness setting, not only is your screen less bright, but it's consuming the same amount of battery power as a good screen at the same setting that looks brighter. You could use less power on a good LG/Samsung-screened computer to get the same brightness.

Getting myself tied in knots :-) just read your post. Makes sense. Went back to calibration again. 6500 is definitely a tinge yellow. But my initial adjustment of 8000 is far too high.

Turns out 6700 or so is about right but i rounded it up to 7000 just to be on the safe side.

Native white point is a shade yellow but a few hundred points upwards appears to remedy that quickly.

I've been using my rMBP for a little over a month now, got it on July 5. My rMBP is 2.6/16/512. I notice some IR when i was on Lion, but it was very light, almost unnoticable. After i clean format to ML it got worst. As it turns out i have the LG, LP154WT1-SJA1 to be exact. I already made an appointment on wednesday to the bar. The bar i'm heading to is in Los Angeles at The Grove. Have anyone gone to that location for a replacement? if so, do they have any replacement, with my spec, in stock?

I just recieved my rMBP 2.6 Ghz base model, week of production - 32. Unfortunately i got an LG screen. My first impressions were that it's a bit dimmer comparing to my 2010 Macbook Pro or 2011 Macbook Air. Also the whites have purple/pink cast. I can't really say how much of this would also show on a Samsung screen, but Im just not amazed. I will test it for retention and if its also there then it goes back to Apple...

Dear UltraMax,

Could you please tell me how to find out if I have LG or Samsung screen, any help would be appericated

I have a strong feeling that I got LG screen but want to confirm that.

cheers

Open Terminal copy & paste this and press enter:

ioreg -lw0 | grep \"EDID\" | sed "/[^<]*</s///" | xxd -p -r | strings -6

If it says LPXXXXXX is  LG, if it says LSNXXXXXX it's a Samsung

Many thanks for your post mate

I got this output which I assume it's LG  ...could you please confirm ?

many thanks in advanced

Wow, thats new.. you got an AUO

Very interested in it's performance, I had a MBA with one, it was very dull...did not display colors well at all
