Q: MacBook Pro Retina display burn-in?

Hello all,

I got my screen replaced yesterday. As per my previous posts, I had an LG screen with image retention (after five minutes top, and very obvious):

LP154WT1-SJA1

My 2nd display, I discovered, is also an LG alas, same bloody numbers and all... :-(

(manufacture date: C9CE8C80)

HAVING SAID THAT, it appears *not* to suffer from image retention! I tested on three different occasions so far with a chessboard background and a dark grey desktop. I tested for 5, 10, and 15 minutes twice yesterday, then 5, 10, 15, 30 minutes this morning.

No IR so far...

Screen appears a bit on the warm side (yellowish) just like my first one, compared to my Apple Cinema Display which appears more on the cool side (blueish). Any of you kind gentlefolks can suggest useful tips to easily calibrate the display? I am not very familiar with the calibration procedure.

LG can screens have yellowish displays...sometimes poor brightness, blowout colors, and other qualities that are hard to live with when you own other macs with bright, crisp, and colorful displays.  Don't waste your time with calibrations, you gain one thing and loose another. The default Apple calibration is the best one

Btw... Hope your IR is gone for good. 

Which is pretty 'ironic' since the Apple Cinema displays use LG panels, and only LG panels

bjiibj,

Thanks for your reply. I actually did some tessts using a few 8-bit gradients and the monitor DOES look like it is only a 6-bit IPS that replicates the 8-bit colors through dithering. Color banding is quite bad even when editing 8-bit images or videos. Increasing the the color range (sRGB Gamut) without incireasing the bit depth is QUITE a disappointment with Apple. I am going to make a few tests with the Sansung display in the store, but I also think it is a simple 6-bit IPS as well.

Not only that, I hear LG was the first supplier os Retina Displays for the mobile devices. My old Macbooks Pro are al LG and work fine.

I have to say this again, but the IR problem can't be replicate in the Boot Screen or in the Recovery Mode, there is some issue with the display configuration. Leave the chessboard on your screen for 10 or 15 minutes, check the gray background, you will see the IR. Immediately restart, you won't see ANY IR on the boot screen. You can also play with the background in the recovery mode using the terminal window, no IR at all there.

I hate all of this... Just wish these monitors were working correctly :(

Truth is, Apple today is far form the great and old "Made in USA" Apple!

That is very different for me, i can replicate it almost anywhere even on Windows 7 bootcamp. I even turn it off for 5 minutes and when i turn it back on it still there, just lighter. I even replicate it in the bar to show the "geniuses", without the checkerboard test, and they agree that it is a problem, but all they can do is tell me to wait for the "Firmware" update which is totally BS.

Very interesting UltraMax, I can't replicate the IR in the Recovery Mode. I think this lack of standard is more concerning, it seems there is a total mess and complete lack of quality control for this display, completely unreliable. Maybe good for gamers, but far from reasonable for professionals.

Go to settings, monitors and then click calibrate, advanced settings, do what it says, when gamma appears try 1800 and the other set it to 7000 you will see no difference with samsung screens and be happy.

I just tested a gradient from black to white and compared to the same image on my old trusty Dell 2405FPW (PVS) desktop display.  The Dell shows no banding whatsoever for the image, but the rMBP does.

I agree; the LG display (probably the Samsung too) is using lower bit depth.  To be honest though, I probably never would have noticed it if it weren't for your post.  I personally can live with it, but once again, if I were an image professional I would be less pleased.

But then, I really don't have extensive experience with LCD panels, and am not an image professional, so I don't know whether this sort of color banding (due to a reduced color bit depth of the display) is common these days or exceptional.

syrius777,

You shouldn't change the gamma without a calibrating hardware like Spyder. The correct gamma for the sRGB gamut (the one used in the Retina Display) is gamma 2.2 and not  1.8, the LG panels seem more correctly calibrated out of the box, at least the ones i could test. The samsung is closer to gamma 1.8, but this is the wrong gamma for this color space. Eventhough the Sansung ICC profile configuration says it is 2.2, it is not. So without a proper hardware you won't be able to know which is the correct gamma for your display.

some LG panels have a pink tint (higher temperature, closer to 7000 and it should be decreased to closer to 6000 or maybe even less). Some are yellowish and should be increased. But the IR doesn't change at all with or without calibration.

Make a clip,proove that:Even when you restart, the IR is there.

You still can calibrate it for yourself if without IR and have it as you wish!
