SR MBP LED LCD yellowish and gradients issue

[Animalk]

I have a C2D MBP non-SR and it has the glossy finish. What you are all seeing in my opinion is the impurities in the material used for the screen. Apple has specifications and criteria on what the translucency of the material used for the screen should be. When you are looking at it straight ahead, you are looking at its designed and tested translucency with minimal variation from direct line of sight (I would say 5 degree to either side at most was tested).
When you look at it from an even greater angle, you can clearly see the display start to loose its lumonisty and color integrity. That is because you are looking through the screen material at and angle and therefore light is trying to pass through a thicker, non-tested peice of material which makes it highly more likely for impurities to show up. Also lets not forget these are LCD displays so they are composed of several hundred thousands of cells which darken the image from an angle to various degrees depending on what material is used to make these cells.

If i look at my MBP head on, its the best display i own (and I own several 20" and up Dell LCD desktop monitors). If i change my view to strike it at an angle, it immediatly looses luminosity and the all the colors are tinted yellowish. The more I increase my angle, the more it becomes apparent.

Granted I dont have an LED equipped MBP, but Apple has confirmed that the luminosity of both the LED and non-LED has been calibrated to be identical in every way other then power consumption.

I don't have yellow tint on C2D MBP and it's not a issue for the old ones. It's issue of LED displays on MBP SR, but you right that viewing angle is one of factors but for what I saw it's just making bigger or smaller...and these two displays are NOT calibrated from factory to same levels in color or luminosity just check the photos....

I have seen the photos and, even though I am starting to doubt Apple on these new LED displays, I am still not 100% convinced that something is wrong with them.

As regards to the calibration, I am only stating what Apple has stated.

 

[mayoko185]

After looking at those pictures I can say mine is nothing like that... I will admit though I did calibrate as the default one did look a little "discolored". the profile PDE linked to had a way to blue/perpule but I made my own and I couldn't be happier

Only thing I can think of now that this is due to the finishings apple is putting on theses displays as another guy with the same display (but /e matte coting) has the issue wile I dont

The one PDE linked to is for a LG panel, I am not surprised it does not work that well on your Samsung

I do have a C2D MacBook Pro and the tint issue is much worse if you are viewing it from the sides.

Alright I just went to see the screens at the local Apple Store, and I think I know which ones have the tint now.

Out of the 4 LED MBPs 2 matte, 2 glossy.
- 1 matte doesn't have the problem the rest do
- The display model for the good one is 9C67, and the other 3 are 9C68.

9C67 is the LG panel, and 9C68 is Samsung from what I've read.

So I think if you have 9C67, you are fine.

Wow, good work!

I've got a 9C67 panel, and I can confirm I've got no noticeable yellowness near the bottom of my screen.

Same here, go go LG!

PDE seems to be the exception to the rule.
9C67, and yellowing.

 

[mayoko185]

Well as I said before I have a 9C68 but I just don't see any yellow tint at the bottom. Maybe there was just a bad batch of samsung panels and I just got lucky and got one w/o a defect? I see the pictures PDE took and mine does not look anything like that...

 

[Xquizit]

I've been watchin this thread for the last few days and haven't said anything since I didn't notice any issues.

I can confirm, however, that I have the 9C67 LCD (by LG apparently?) and I am experiencing no discoloration.

Just curious, are the other layers of the screen "replaceable" or are they part of the screen?

It might be that layer which is busted.

 

[Wallace86]

So, SandmanTR has the yellowing problem, mayoko185 doesn't... but they both have the same panel.

I declare shenanigans on Apple.

yes....that is the only reasonable thing to do at this point.

I'm sure Apple will just replace the whole lid of the MBP.
Pulling apart an LCD screen would be incredibly difficult with anything other than robotics, I should think.

Where is the screen model number written?

 

[SandmanTR]

Where is the screen model number written?

Open the Color LCD Profile, scroll down to #13 which is "Apple display make and model information".

 

[Habusho]

9C68 Glossy and definite yellow discoloring at the bottom of the screen.

I do have a C2D MacBook Pro and the tint issue is much worse if you are viewing it from the sides.

YEAH but that's like 60 degrees! I'm talking around 90 degrees +-30 degrees to sides...which correspond with specification of viewing angle. And in this section there is no discoloration as I saw in the same viewing angles in LED. I was looking straight as I could in both levels horizontal and vertical and i saw tint at 1/4 of the SR MBP display

Common of course there is some distortion when you looking in sharp angles, but this discussion is when you looking in ordinary straight forward angles at the display.

I'm sending link for this discussion to apple. Hope will reach higher levels anybody want to make official complain is welcome.

Talked to Apple yesterday and they forced me to go through stupid troubleshooting. They had 'never heard of this problem' and said there was no engineering review of the displays. Since I have the yellow tint and a non-functioning right arrow key, they told me it would be silly to send it in for repair if I can just return it for a replacement. I agree. It's going back to amazon and I'm going to get another one at the Apple Store on Monday just so that it would be easy to replace if something is wrong again.

The yellowish tint IS a noticeable and my choices are either to use the default ColorLCD profile and have the whole screen be yellowish, or to use a calibrated profile and have one third yellow at the bottom of the display. . I have been trying to get used to it but, quite frankly, why should I? I'm hoping that this is not the beginning of another display fiasco. I was very excited when I first got the computer because apple had dealt with both the grain and the uneven illumination, but it's not acceptable to me that there is a yellow hue. I wish Apple could use the same displays as many other manufacturers. When I look in stores, they mostly look great and I'd be satisfied with most of them. I'm asking for: even illumination, no grain, good contrast, little edge bleeding, white whites and black blacks. It's not like the technology doesn't exist, but for some reason apple is having trouble using it.



I'll report back when I get the new one. I'm hoping it will be fine.

 

[kelau09]

does it count, only noticed when i view the screen from both sides.no yellowish tint when viewing in the front.
Also the gradient colours look terrible, obvious banding issue.
i'm thinking about taking it back.
damn, i've spend half day transfering data and installing softwares.

Do not be so picky. You are not affected by the tint issue. It is a laptop, not a $1000 S-IPS screen.

What? i just spend $2500 for a pro laptop, i think i have the right to be picky.

 

[iW00t]

Please check how much other non pro laptops with similar processor and GPUs cost, and come back again.

That you spent $2500 on a laptop is irrelevant. The screens are excellent IMO, but whatever floats your boat, and you are perfectly entitled to your opinion.
