Hey
I just run LCD TEST on my new :apple: SR MBP and as well on mine "old" Generation 2.2 :apple: MBP (actually 4weeks old but can't return it) and in gradients test the LED LCD provided some wierd results :confused: (one horrizontal line and one curved one across the whole test) Also it's seems a bottom part of screen is going little yellowish, anybody has this experience:cool: :( :confused: ?

I've noticed that when viewed at an angle, it looks yellowish. Quite yellowish. Also casts a yellowish glow on the keyboard too.

I'm not sure if it bothers me or not.

It's matte, but that doesn't matter, that's just finishing, the display is the same underneath.

Color Sync Utility will do gamut in whole display not selectively just in lower parts, that's not a good advice. Or you ment the gradient issue? That's very wierd stuff, so please try somebody else as well if you will see a curved and horizontal line in the gradients.

I'm glad that it's not just me. It is a little annoying sometimes. I usually prefer bluish tint than yellow. Bottom half of the screen looks a little yellow/darker on white. You can test by place 2 browser windows with http://www.apple.com/. One on top half and one on the bottom. The white "Leopard" text look different isn't it?

So now the hard part,

so if there is a flicker issue as posted on several forums

and

now it's this uneven yellowish tint on different places of display (mine bottom, somebody's side)

so if I will go to Apple Store and replace this unit, for sure I will get the flicker one, then another yelowish and so on and on and on...

As I work mainly for colorgrading this is a issue for me (and yeah I should buy a Cinemadisplay and I will but...) in field work I need to get a good performing display!

So change or wait till last moment? (BTW How is it? You can return it or change it in month after purchase, so if I will pick new one will it automat. extend the month period? Or this issues are covered by 1 year warranty...

I put my old MBP away, no more looking side by side. I'm just happy that I don't have a dead pixel or any other problem. Now start enjoying the new snappy machine.

Now, someone make Pantone Huey Pro work for this new LED screen, I'll be really happy. I had a hard time calibrating by eye, so it's back to default for now.

Why can't the Huey work with the new screens? The Monacco XR gave me a bit of flack because the screen is supposedly too bright even on the minimum setting, but it still "sort of" calibrates fine :D

Well after the calibration the screen would look super purple when you move your head down and look up to the screen. Green when you move your head up and look down. And while looking at it straight on, top is a little purple, middle is white, bottom is a little green. It's just weird. I would take pictures but my camera isn't here at the moment.

I noticed it too, but it is heaven compared to the old ones, so I am happy.

See? I am not impossible to please! :rolleyes:

You got yours???!! Liking it?

Yes, I've noticed this too. The bottom quarter is slightly darker than the top three quarters - or does it just have a slight yellowish tint? I assumed it was just that it was a little darker...

I'm with you: it's so much better than the old ones that it's hard to complain!

Is it an either or thing? I mean, perhaps all of them have this yellowish tint/darker area?

Then Look on that GRADIENT that's a serious issue if the display can't display proper 24bits

Hasn't this been covered many many times, concluding that no laptops show 8-bit (24-bit) colors but just 6-bit (18-bit)?

The gradient test shows what we all know already, namely that these displays are 6 bit, not 8 bit. All current notebook displays are 6 bit - just go to the manufacturers' websites and you'll see.

We've got to move on...

I can't believe you guys are okay with this - I just bought a 15" MBP to replace my PowerBook G4, and I am rather annoyed that the bottom 1/3 of the screen is yellowish.

If they're really all like this, what can I do? Maybe if I wait a while before returning it, they'll get a new shipment in.

That's strange, I played with 15" LED both matte and glossy at local Apple store and didn't notice this issue. I do notice matte is slightly brighter than glossy at the highest level of brightness, and glossy has more of the yellowish tint overall from side angle viewing, but nothing like sectional yellowish tint. If this is an issue with certain batch of the MBP, you might want to consider exchange with Apple store before the 14-day period. I also ran the LCD test on my Napa C2D, there is no horizontal line or curve, only the 6-bit gradient issue.

Well you can't see the lines on the OLD Mercury display, but you CAN see them on the new LED...isn't it strange?

Yeah I will propably do the same wait if something will happen...(firmware, update, common change?)

To be honest, it took several days to notice this because I hadn't calibrated the display. Using the terrible ColorLCD profile, the whole display has the same tint to it so you can't see it at all. It's only when whites are genuinely white that the lower part is noticeable.

I've been through more MBPs and macbooks over the past year than computers over the past 14 years so I'm really hesitant to send this one back, especially if it's a wider problem.

As I said, the only way you can see this is if your display is calibrated and whites are really white. The default ColorLCD profile somehow covers it completely.
