MacBook Pro Retina display burn-in?

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.

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.

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!

Old Apple Macbooks (2002 and before) were - amazingly - true 8-bit depth, they were the FIRST and only. Nowadays it is common for all mobile computers to be 6-bit, i think some thinkpads are 8-bit as well (they also used to be). The greates problem is that when you increase the color gamut (form 66.9% of the sRGB space to 99% of the sRGB space that demands 8-bit depth for precise color reproduction) without increasing the bit depth, image artifacts like dithering become more appearent. But almost all IPS LCDs are just 6-bit.

syrius777,

True, but if you work with images, photos or videos, that won't do, you have to keep a proper calibrated monitor. If you are using it just for fun or basics it is ok to have any calibration you want or sort of. As long as you accept you won't be displaying images and videos in the correct way since they were edited to be displayed in proper calibrated display. It is the same thing for Home Theaters.

You can still try 1800 if you want it more blueish than yellowish on lg,nothing wrong with it.

Yes you are right about the 2200 but its still up to the user i think.If yellowish is a problem for him... i personaly like 2200 looks more natural

I have just received MacBook Retina today. It shows ghost image after 15-20 minutes. My concern isn't the esthetics or lack of perfection. I'm worried that the screen may gradually unfold a serious fault after a year or later when you're not covered for a repair or replacement.

Apple UK technical support has confirmed and recorded as 'Hardware Fault' eligible for repair or return/refund. I have an impression that they know about this issue very well. I hope that Apple will deal with this manufacturing problem..... so for now I will not be placing any new orders for Retina models.

hey 8212!

I was thinking about a preemptive return but i just cant justify it.

Side by side with my 2010 MBP i cant see any yellowness - if there was visible IR i would do... i have the three year apple care so if IR does manifest then i'll deffo kick up an allmighty fuss.

Another problem is that I have a dissertation due in 6 weeks. Mt old MBP has a new owner and I can't afford any downtime!!

Good luck though!

Btw to an earlier poster that said "LG was an up and coming manufacturer" untrue. LG has been around for a LONG time. Its just they used to be called Goldstar.

Also in appliances yes its true LG is known for their lack of quality control.

LG is a simple company. They changed the name to LG because Goldstar was indicative of low market products and everybody knew it at the time. Most of you aren't old enough to remember.

LG went marketing crazy, redesigned everything to look "sleek" and slowl raised their prices across the board.

Now most LG products look sleek, cool, and they have marketing everywhere so people naturally figure they must be pretty good. Isn't really the case.

I left the "About Downloads" doc open for exactly 5 minutes before i made this video. http://youtu.be/muDE26OFM1k

I remember Goldstar. Universally known for makng low end garbage. I didn't know that they became LG. I'd forgotten all about them.
