Q: MacBook Pro Retina display burn-in?

I have a Spyder 3 Express (which contains the same puck as the Spyder 3 Elite/Pro) and I used the Coloreyes Display Pro software to calibrate the original LG display that came with my rMBP and it had no effect. I did not even bother to calibrate the first replacement display I had. The rMBP is currently in the shop for the 2nd replacement display.

Just to update, the new command provided by rrahimi made a difference and it looks like they've replaced mine with another LG.

Color LCD

No signs of IR as yet, but as some have mentioned it may take time to show up.  I'll monitor and report back.

Wow. Well I just ordered tonight so I guess I'll wait and see

I've been following this discussion since the beginning and can't believe how much hassle this has been so some of you guys. I was ready to order on day one but held off just in case to see if any early adopters were noticing any issues with the new rMBP - so glad I did. I took the decision to hold off until things appeared to settle but at the moment it's difficult to see if things are improving for new orders or not.

I have a few queries that some of you may be able to help with. Whenever I've ordered a portable Apple machine I've always ordered AppleCare at the same time, I've now had several Apple laptops (early PowerBooks onwards) and only once had a machine with problems (6 replacement screens on a 17" MBP - don't ask...) - but here's my query - if I order AppleCare at the same time as purchasing the laptop the AppleCare is auto-enrolled; so what happens if the machine laptop is replaced (if for instance it has a dodgy LG display) or I ask for a refund.

As far as I understand it, once enrolled the AppleCare is specifically attributed to a machine serial number so if a 'new' laptop replacement is made does the serial number get updated/transfered on the AppleCare policy? Or if a refund is given on a laptop presumably they refund the cost of the AppleCare too?

I'm in the UK; I'd be very interested to know what the current situation is with which type of display people are receiving LG/Samsung/AUO with new orders coming pre-installed with 10.8 Mountain Lion.

As always, any feedback gratefully received.

Many thanks -

1. WRONG: from your own document:

 

 

When voltage is applied to a cell, the crystals of that cell all make a 90-degrees turn. By the way, an IPS panel lets the backlight pass through in its active state and shutters it in its passive state (when no voltage is applied), so if a thin-film transistor crashes, the corresponding pixel will always remain black, unlike with TN matrices.

 

 

IPS cells are either ON or OFF ONLY Like I said it, there are NO diferent levels of "twists".

 

Shame you didnt keep reading, because half a page later there is a nice pictorial of how IPS achieves different brightness... via different crystal orientations and the use of a polarizer.

The original statement is misleading and probably should have said "When full voltage is applied to a cell, the crystals of that cell all make a 90-degrees turn.".

3. WRONG, there are only 2 electrodes PER PIXEL, not subpixel. and IPS does not put electrodes in a different substrate, and you can even find this explicitly explained in the document you posted, and you can even find a few graphics there where it is more than crystal clear that the IPS crystal doesn't even twist, it simply turns - It is not a TWISTED crystal from like TWISTED Nematic - and the there is also a few graphics where you can see the subpixels between the 2 electrodes.

There are most certainly 2 electrodes per subpixel. I don't see anything in that document that would indicate otherwise.

BTW, lower contrast = less shades. 

A flashlight has an incredibly high contrast ratio. But it only has 2 shades: Off and OMG Bright.

The rest of your post looks correct, although I still don't see how non-local dimming of the backlight supply results in well-defined image retention due to the phosphors (which are part of the backlight). Perhaps you are under the misconception that modern LCDs are directly backlit by the LEDs.

The LEDs themselves reside along the edges of the panels are actually blue with a yellow phosphor which when mixed together produces white light.

This white light then is sent through a diffuser film so as to create an even white light behind the panel before it passes through the liquid crystals.

If they replace a machine for you, you will have to call them up and have the Apple Care policy transferred over to the new machine with the new s/n. Catch is that the policy does not have its start date refreshed, so you effectively lose however long you had the defective machine, and however long you had to wait for the replacement from the cover.

If you end up going for a refund, they will also refund the cost of the Apple Care policy.

I am in the UK, the last two replacements i have had were pre installed with ML and they both had LG screens, both defective.

Thanks salthustle, very helpful information, sorry to hear of your experiences with the LG displays.

I'll be very interested to hear how you get on with your new awaited replacement.

Thanks again

Finally saw the issue in person.  Went up to the local Apple Shop (iStudio in Bangkok) and ran a 5 minute test on Safari and bam... image retention.  LG display. 

It might be a good % of the LG displays are bad.. just people haven't woken up to the issue yet. Has anyone had their rMBP for more than a month with an LG display and no IR? 

Just received my 2nd replacement (rMBP, 2.6ghz, 16gb, 512gb).

A short summary and some pictures:

• 1st rMBP: Week?? Samsung screen, with a very annoying dead pixel right in the center of the screen: called apple support and received a new one without any problems.
• 2nd rMBP: Week31 LG screen. Noticed the IR problems quite quickly: called apple support and again, recieved a new one without problem
• 3rd rMBP: Week34 Samsung screen, perfect condition!

The 2nd rMBP has not been collected for return yet, giving me the opportunity to compare the two (LG vs Samsung) side by side, also with some pictures including checkerboard tests.

Left side: LG. Right side: Samsung

Both laptops at maximum brightness and standard setting (no calibration of screen/color settings)

Picture 1: side by side

Picture 2: White vs White

Picture 3: Checkerboard background on both

Picture 4: Closeup of LG after 10min and changing background to dark grey

Picture 5: Closeup of Samsung after 10 minutes and background set to grey

In my opinion the Samsung screen is indeed the better one: it seems to be slightly brighter, whites are less yellow than the LG and most importantly: no IR.

Glad I made the exchange. I think Apple should solve this difference in screen-quality, it is just too big to ignore.

On the other hand, I have to say i'm quite impressed with Apple's customer service: they've been very polite and helpful and replaced my two faulty units without difficulty. (both times within 14days after purchase, online store, Netherlands).

It seems the ship time has gone down to 2-4 business days in the US.  Let us know, I may be ordering one soon too.

In stock in the Thai store

In stock on the UK Online store, but if you upgrade RAM / SSD it's still 5-7 days dispatch

yoast2011, thanks so much for posting these - first time I've been able to see the difference between the 2 screens side-by-side. It looks as if LG might have better blacks, but the 2nd photo clearly shows that the white point is yellow in comparison to the samsung. And yes, the IR issue is terrible! Makes me even more determined that I want a samsung screen. IR-aside, that white point bothers me a lot. I'm using an LG right now (yellow and IR issues - going back in a few days).

Seems ridiculous that the screens can differ so much and be sold overall as part of the same product. I'm sure some people prefer the look of the LG, but surely that is the point - allowing everyone spending this much money to get the product they want and deserve, whether that be a Samsung screen, or a (touch wood it can happen) an IR-free LG.

Can't believe Apple still haven't said anything official about this. They must be getting loads more returns than 'normal'.

I have a Macbook Retina with LG display and, of course, i am experiencing image retention.

I have developed a small app to evaluate and keep track of the retention level of my display and to compare it with other ones in a measurable way. It shows a fullscreen checkboard for a user-selectable amount of time, then it displays a gray background, giving to the user the possibility to stop a timer when the ghosting issue disappears.

It also display the model and serial number of the display.

If anyone wants to try, it can be downloaded from:

I hope it would help someone

On my previous posts I declared to the forum that I convinced myself to stay behind on buying this product till apple solves this problem. But I can't resist long to keep my promise and yesterday I went out and bought one from a reseller (FNAC). And what I am unlucky, it is LG (Week 28 July). And after I made the test for about 20 minutes, I see a slight IR. I will keep testing and if it gets worth, I go back to the shop and ask for a replacement. Yesterday before buying I talked to someone in the shop concerning this issue and promised me to bring it back before 14 days if I see this kind of problem. My question is ----- Is there someone from Belgium who expriense this IR problem and who succeed to replace the panel with a Samsung one?
