Yellow tint and dead/stuck pixel test for i5 & i7 MBPs

Come on now.............. you're being a bit harsh with the trolls. ;)

To some degree you may be right saying people are reading too much into this. However, some of us do have real concerns and the colour shifts are quite dramatic. Maybe you just play games, surf the web and never really notice these differences but to someone who makes a living with their computer your being very dismissive and a little blinkered from your fanboy standpoint.

I would be reluctant to live with my screen shortcomings if I didn't already own a 2006 17" iMac using a TN display without any colour drifts. The luminance may not be 100% uniform (property of TN displays limited viewing angles) but there sure as heck is no colour drift.

I have attached a photograph, not a screen grab of my MacBook Pros screen highlighting my issue. I have never had much luck with Apple displays in the past as you can see from the attached second photo of a 23" Cinema display showing similar issues with colour drifts I returned. An IPS display!

dude, the shift is in the photo itself. the thumbnail next to it shows exactly the same gradient.

Dude, it was a plain white background!:confused:

The lighting feathers off but the colour should not change other than going darker/greyer.
 
My Samsung LCD HDTV which I use as a computer monitor failed the yellow test (the bottom grey bar was lighter than the top). Honestly, I don't notice the difference during regular usage so I'm not worried. I didn't notice any stuck pixels (knock on wood).

I see the same shift in upper right corner of the thumbnail as well. I doubt this is a screen issue if the same sort of effect is occurring in different parts of the screen at different scales.

@ gazwas: Have you moved that application window around the screen to see if the same color shift in the photo is present in all areas of the screen? Bottom quadrants, far left/right, upper left quadrant? If you still see the same thing it's not an issue with the screen itself.

Comparing to the 23" ACD isn't exactly that objective either. Those screens were plagued with pinkish tinging/uniformity issues ever since they were released, and this issue was well known.

You are right about Apple's displays not being that great, however. I've owned a 30" ACD where the left third had backlight uniformity issues, and my current 24" ACD also has similar uniformity issues too. (despite exchanging it) Part of it is in the nature of LCD technology...which is why I have a Panasonic plasma for my HDTV setup -- way better color, contrast, & uniformity. :D
 
After 5 replacements and a 6th one I had a look at, I'd like to know: what do you guys think is the best chance of getting a good one with a good screen? The Apple Store manager told me to either wait for a few weeks for new batches to come in or to call Apple Care and complain and maybe (if possible) order one and have them check it before they send it.
 
15.4" i7 Highres Anti glare screen and everything is fine. No yellow tint / dead pixels

Maybe your eyes need to be repaired ? :)

5 different mac's and still the same problem? Or you really have bad luck or you are just looking at the screen in the wrong angle.

If only it were "just" yellow tinge issues.. out of the 5 macbook pros, 3 had dead or stuck pixels and 2 had backlight bleeding.
 
So I just got back from the local Apple store to check out some of the displays on their 15 and 17 in MBPs. (mainly for my own sanity)

All of the notebooks I looked at (2 15" std. res glossy, 1 17" glossy, and 1 17" anti-glare, all at max brightness) exhibited the color shift phenomenon where the top third appears bluer than the bottom third.

I opened up all the "tests" linked in this thread, and also compared the alternating blue and white rows in iTunes/Safari download window by moving the windows to the top, middle, and bottom thirds of the screen. In all cases, the result was the same - bluer at top, yellower/brighter at bottom. The lagom.nl viewing angle test was the most telling, with all 4 screens demonstrating the blue-white-red shift in text color. Interestingly the worst of the 4 was the 17" anti-glare.

I'm pretty much convinced that at least in my case, (and potentially others here), this color shift effect is due to the poor viewing angles characteristic of TN displays.

The effect can be mitigated by viewing the screen from a farther distance, but it will always be there. If you tend to hunch over your laptop (like me) to get in closer to the screen, it may be a good idea to start adopting proper posture and sit so that you're viewing the screen from at least 2 screen diagonals away. :)
 
Is it not possible (nay, probable) that all of you yellow-tinge fanatics simple don't know how to color-calibrate a screen? That perhaps the factory defaults are not necessarily the most perfect calibration stage your laptop monitor could be at?

For that matter, why do any of you even care? Most of your are going to do not much more than e-mail, music, and surf MacRumors. If you are a design professional who relies on having accurate color representation, you shouldn't even be relying on this screen for checking color; you should be using an external Eizo monitor or something similar. Hell, a cheap CRT monitor with a Pantone Huey are much more accurate than a laptop screen.
 
No dead/stuck pixels, no yellow tint whatsoever and no backlight bleeding issues when temperatures rise here!

Perfect 17" i7 2.66GHz model at 1st try. :D

+1000

:p
 
For the record my 3 month old 17" HP with Win 7 passed the tests perfectly. To stay ON topic though the 17" i7 MBP I ordered 3 hours ago better be perfect considering it was THREE times the cost of this machine!
 
no dead pixels
the bar test..the top one seems a smudge darker... I don't think it worth risking that it could be worse

i5 2.4
15" Hi Res Glossy

No yellowing, no stuck or dead pixels. Just a perfectly beautiful screen.

*whew* :p

My screen looks fine as well. I guess if you really, really, really, look for it, you can see the angle dependent characteristics of the display.

See post #33 for a good explanation.

There really aren't any issues at all. There are just a few very very very anal retentive people making other new macbook pro owners paranoid, imo.

My i7 15" high-res glossy is a beautiful machine and as close to perfection as you can get in this world.
 
My i5 15" 2.4 hi-res glossy has the yellow tint :(

Just got a new one shipped out, pray for me guys!
