Q: MacBook Pro Retina display burn-in?

Merch,

The colors displayed on your screen in each "Pixel" are actually comprised of 3 LED's: Red, Green, Blue.  Represented as such to produce pure RED: 255, 0, 0.... PURPLE would be 255, 0, 255,.... with a lot of variations Using 8-Bit color as an example.... Each of the LED's are adjusted on a scale of 0-255 to produce a color by mixing the 3 colors. Those LED's can have variences in production and quality.  The programming will tell the screen to "turn up red to 255"... but that particular LED might be a little brighter than 255 or a little duller.....

Anyway. I wrote an article in "Laymans" terms a while back because a friend asked me. Perhaps it will help you to understand why this can be calibrated to fix....  The adjustments made by a color profile should be something you can grasp as a programmer:

MatryF81, can't you do it for free somehow?

Go System Preferences > Displays > Color > (select) Color LCD > Calibrate > (check) Expert Mode > Continue > (leave all 5 "native response" screens unchanged) > Continue > (check) Use native gamma > Continue > (uncheck) Use native white point > move the slider between 7000K and 9300K to find a blueish tone that lessens the nauseating feeling you get when you look at your $2,200 computer screen. 

I've personally found that trying to change the 5 "native response" screens always just made things worse and I was unsuccesful at using those controls to remove the yellow. I believe that the problem with this display isn't that it's yellow but rather that it's blue deficient, that it doesn't show blue properly. You can use iPhone apps to measure the red/green/blue components of the light.

Hey, Coco, does your Apple logo on the top of the display cover glow pink instead of white?

Thanks, Marty; I will read your blog post.

Coco, Mac OS-X has a Color Calibration software built in that you can use. But you are trusting your eyes to make the decision and your eyes WILL decieve you and to be honest it does more of a "Macro" level adjustment, and the best way is with "Micro" level adjustments that only a Calibrator can detect by which it will end with programming a ICC color profile.

 

Spending $90 on a Color Calibrator may seem like a lot of money, but it will work for years to come and you can probably split the price with friends or family who you can calibrate as well.

Hi Coco_Jambo,

MartyF81 knows what he's talking about.

I, too, was really surprised to see the difference between the way my uncalibrated screen looked and the way my screen looked after calibrating it with my Spyder4 Pro. It's pretty noticeable and definitely more on the warm side (AKA yellow-ish). It's quite possible that your new screen is actually more accurate than your last one, but you've been looking at the previous screen so long that your brain has defined that color profile as normal. Proper calibration will reveal whether or not that's true. In any case, you should soon get used to it and you will likely find screens with color profiles similar to your previous one look too cool (AKA blue-ish).

How do you know that your post-calibration Samsung display is showing colours accurately?

Could you please start another theard to discuss your calibration stuff. This has nothing to do with IR.

Actually it does because people are getting their LG displays that have IR replaced and are getting them replaced Samsung displays that they thing have another issue, but actually do not. Just because it is not help ful to you, does not mean it is not helpful to others.

I agree. This calibration discussion relates directly to the IR issue, because some people on this thread are claiming that there is, in essence, no solution to this problem because the Samsung displays are just as bad as the LG displays, but in a different way (yellow-ishness versus image retention). I don't think this is true and I believe that, barring a redesign of the LG panels, the only reasonable solution, right now, is to replace LG panels with Samsung panels.

Some Samsung panels may indeed be defective, and we're not saying there aren't some bad ones out there, but they're rarer and not endemic like the image retention issue appears to be with the LG panels.

Agreed. I don't think there is anything wrong with the Samsungs.  Mine looked warm when I got it, but I was able to calibrate it to Neutral. I am looking at mine right now and it is actually a bit "Cool" (blue) because I used a cooler calibration to create ICC profile for gaming as it is easier on my eyes. But the point of what I am saying is that I was able to move it from hot to cold.

Then prove it. Take photographs along-side another display. Record a video and post it on YouTube. I don't believe your calibrated display looks as good as the original LGs or the good Samsungs that Apple is showing in store. Take your calibrated Samsung display and set it beside a Samsung display unit in an Apple store and take a picture.

I agree with you. I do understand the "Warm" effect but almost every single Samsung display I have seen has not only been warm, but have had yellowish blotches in various parts of the screen. I have had several of these units and have returned them all. What I do have is the SJA2 panel and I can tell you the display is much better. This of course is my opinion but I have yet to see yellow blotching on the LG's.

Merch come on man... I explained it above. You are going to be looking at the picture on YOUR "uncalibrated" display, as well as the camera itself is going to adjust the white balance in the camera.

If you cannot understand that, then you do not understand the concept/science at all. The only way to "prove it" would be for you to be standing next to me in the store. Taking a picture of a screen to "prove" color is like taking a picture of a hot dog to demonstrate "taste".

My request has always between to show me two screens, not one. The difference in quality should be apparent in the comparison.

Heres another pic. ASUS on left I removed the calibration on. It is "warm" the R-MBP on right is calibrated neutral.

OK, thanks, I appreciate that. But I won't be satisfied until I see a calibrated Samsung Retina MacBook Pro display next to an uncalibrated Samsung Retina MacBook Pro display in an Apple store because the displays in the Apple store is what I agreed to buy. I suspect these yellow replacement Samsung displays don't have the contrast and colour vibrancy of the LG or in-store Samsung displays. I will also read your blog post when I have a chance.
