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

My last MBP, late 2007 model, had some very minor discoloration, and some minor backlight bleeding in the corners. I think just about any LCD screen is going to suffer from some slight discoloration as you move along the screen.

It will change depending on your viewing angle. You can usually move your head from side to side and see the discoloration change ever so slightly. My LCD screen on my company monitor actually has a slight blue discoloration right in the middle of the screen. However, if I move my head to the side, the discoloration will fade just a little bit to the point where it is no longer a factor.

I always find that once somebody tells you about the problem, more people start top notice the problem. Some people are very sensitive to discoloration, while for others, the problem is not a big deal.
 
No yellow tint or pixel issues on my 15" Core i7 with anti-glare. Looking at the screen, yes, one could get the impression that the bottom of the screen is slightly lighter than the top of the machine. But, as a photographer that knows about the important properties of light and reflectivity, it is my belief that the light being thrown off by the screen is reflecting upon the top surface and keyboard of the laptop and some of that reflected light is causing the false appearance of a lightening of the bottom of the screen. And there's also the factor of how your eyes react to the changes in the bright screen vs. the (comparatively) dark top surface and keyboard. The more your eyes move toward the bottom of the screen, the more your eyes are dealing with larger contrasts.

Want to see how much the top surface and keyboard impact the screen? Turn the MacBook completely off and look at the screen from a normal position. In a room with even moderate light, marvel how you can see the top surface and keyboard reflected in the dark screen but you only really see it toward the bottom of the screen.

Also, if you display the two grey stripes (yellow test) and angle the MacBook's lid all the way back as far as it will go, and then lower your eyes down to the level of the keyboard and look up (so you are reverse duplicating the way you look down on the display from above), the lower stripe is darker than the top stripe.

It's a non-issue. This forum is filled with too many nitpicking worry warts.

Just checked my 15" i7 MBP with Regular Glossy Display and it has no dead/stuck pixels and no yellow tint to the display.

I think the yellow display some people are experiencing is the reflection of light like others have mentioned.

I wouldn't consider this poster's issue as being too nitpicky. And I don't see how the keyboard could cause this kind of yellowness from a reflection in a completely dark room:

Looks yellow to me and completely unacceptable in a $2700 laptop.

I tend to agree, it's around the bottom left and goes toward the top right, if it was the keyboard wouldn't it be an even band across the bottom of the screen? Especially as it's a photo taken face on not from an angle, which could have created that effect should there have be a light source in the room.

That glossy is rather reflective though. :rolleyes:

Please read what I wrote. I was addressing the folks that are concerned about the lower portion of their display being lighter vs. the top. The yellow tint is a completely different issue and probably has more to do with color calibration settings than any sort of real hardware issue.

I think this has more to do with viewing angles and the fact that the MBP still uses a TN display.

If you try the viewing angle test here:
http://www.lagom.nl/lcd-test/viewing_angle.php

It's pretty obvious (at least on my 15" Hi-res glossy display) that viewing angle is an issue. The text in the top half of the screen appears blue, the middle blends in, and the bottom half is red. If you move your head around the text "changes" color accordingly.

If you scroll down you can see a couple of screenshots showing what a TN display should look like when doing this test. My new 15" display looks exactly like those screenshots.

I think this effect is also exacerbated by larger screen sizes. My mid-2007 15" MBP had a similar appearance, where the lower half of the screen appeared lighter/yellower than the top. My current 13" MBP has it to a lesser degree, possibly because the smaller screen results in a narrower angle between your eye's horizontal to the center of the screen and top/bottom portions of the screen, making it appear more uniform.
 
I went through another 2 MacBook Pros today and then got another refund :(

MacBook Pro 15" HiRes, AntiGlare: Stuck pixel, yellow tinge (bad)
MacBook Pro 17", AntiGlare: yellow tinge (mild), backlight bleeding along the bottom.

What screens did the iMac G4s use? TN as well right? ... because it sure isn't a 'PRO' product and the screen does NOT have any backlight issues, dead or stuck pixels, yellow tinge issues or else and it's 7 years old :mad:

This is encouraging. Once I get my $2700 super computer, I will take a look at the screen using this as well.

Based on what you say, the bottom 1/3 of the screen should blend in if I am eye-level with the bottom 1/3 area.

Can some of the posters who said they had problems earlier do this and report back your findings?
 
I have the 17" i5 glossy. Did every test i found in these forums and on the internet and my display is 100% perfect. ZERO dead or stuck pixels and ZERO yellow tinge. Now if i can only get my fully charged battery to last more than 4 hours and 30 minutes.
 
I'm having similar issues with my 17" i7.

I have attached a couple of shots of the screen to show people that the problem is real and not just a viewing angle problem. These are taken after a full calibration with a monitor calibrator that has turned my green issues into magenta (opposite colour of green) colour casts. The calibrator has obviously picked up the green and compensated for it but because of the colour drift across the LCD, other areas have gone magenta.

I'm a photographer so pretty sensitive to this stuff and colour shifts across the scream could cause me real problems. Never mind trying to explain to the client "it will all be fine in the end when its printed":D

Picture one shows the full screen view of my colour swatch test and picture two show my major concern for colour drifts. If you look at the image of the pottery, the top right drifts to magenta.

My office machine, an £800 2006 white iMac with a TN screen shows no such problem were as my shiny new £2100 MacBook Pro does.

Going back the the Apple store on Friday to see what they say.

Just ned to purchase a monitor calibrator. I use the Xrite i1Display2 and works great with my other Macs. I calibrate for Gamma 2.2, D6000 and with a luminance of between 80-100cdm2.

Calibrator software does all the rest.

The rest is a bit of trial and error until your happy with your settings for that particular display. Everyones monitor will be a little different.
 
thanks for the link to the sites, I will be a first time mac user and would hate to have a yellow tinge issue but I did not see any Yellowing or magent-ing on the right side of the pottery picture. I hope to be able to test that my Mac is in its optimal shape and want to learn how to test out for tinge issues. Could someone please help me understand.
 
I can't really tell if I'm having a tint issue or not. The grey bar ont he bottom looks a bit lighter. Here's an iphone pic of my screen. What do you think?

Here is another way to test your screen :

Click on finder

Goto your home directory and click detailed view. (the second view in the 4 options available)

You will see blue lines in the background

Compare that to the blue lines at the bottom of the screen.

If those are internal screen dumps from Mac OS (CMD+Shift+3, CMD+Shift+4) then there's an issue with how your machine is displaying colors. A viewing angle issue or physical defect in the LCD (ie dead pixel, non-uniform backlight) won't be captured in a screen dump.

You can confirm this by taking a screenshot with Mac OS' built in command and viewing the resulting PNG on a separate display, preferably a higher quality IPS-based panel.

I used a fullscreen capture of an empty iTunes playlist. The alternating blue and white rows appear bluer on the top third, and yellower on the bottom third if my screen. If I move my head up and down, these color shifts change accordingly. Viewing a captured image of this screen on an external IPS monitor (where viewing angle shouldn't matter as much) shows that at least internally, the color is uniform - I don't see the blue to yellow shift from top to bottom.

In my case, what I see looks to be due to viewing angle.
 
I think the tint problem is an inherent issue with TN-based panels. This may be particularly pronounced with laptops where the viewing angle (particularly vertical) is quite variable and depending on how the screen is tilted the tint will come and go. This is different than what was happening with the iMac which uses an IPS screen and should not suffer from dramatic changes in hues due to viewing angle changes.
 
Another devious thread devised by the same bunch of smirkers, fresh from their iMac yellow tinge adventures, now turning to the latest computers. I see some have already (supposedly) returned three or four MBPs, following on from five or six iMacs.
They insult YOU with their drivel. They laugh when they see the impressionable reporting how they too have returned their computers, for no good reason. They want only to spread dissatisfaction and confuse the readership here, week after week, product after product. We all know people experience problems with any kind of product and for those people we have sympathy. But the smirkers are out to convince that ALL products in a range are so bad that they should all be returned or avoided. They love the reactions they get from a sensitive and nervous audience that believes it is getting friendly advice when in fact they are communicating with peddlers of doubt.
Anyone doing that daft tapplox test on a laptop needs their head examined, not the screen. Every laptop screen will show inconsistency in such a "test" because of the very nature of vertical viewing with such screens. Any half-wit knows that a small movement of the head or even 3-degrees of lid movement will alter the contrast across the height of the screen and cause color shifts. It's always been the same. The "test" is not a test at all, but rather a trap for the gullible to fall into. They might as well simply say no Apple laptop in history has ever been worth buying and tell people to compare their portable's screen with a Cinema Display and if it doesn't match it for viewing angles etc, to take it back to the store.
Don't allow yourselves to be manipulated by these creeps. Ask to see the receipts for their imaginary multiple returns, instead of asking for photos. Look at their join-dates and ask what their game has been since.
Or alternatively, be their stooge and give them a laugh. At your expense.
