New MBP Owners (since 8/13/07), Do You Have The Bottom 3rd Yellowing Issue?

Hey guys ... take a look at this :

I had a yellowish Samsung screen ... took it back for repair ... now I have a white LG screen with no backlight bleeding.

on the left is a Samsung LCD for my PC, on the right side we have a macbook pro with a LG LED screen
Before calibration (totally washed out colors):



After calibration (looks perfect to me):



Huge difference huh ? what say you ?
 
Nice job! Perhaps you can post the profile you created so others, too, can benefit.

Congratulations! Maybe repair is the way to go if people are tired
of exchanging? Anything special placed in the repair order that helped
you get an LG display?

I've decided to return my week 39 sammy. I'm going to wait a couple
of weeks for leopard and try one more time. Hoping for a
no backlight bleed LG...

So if you actually care enough about colour reproduction to complain about the bottom part of your screen being a little yellowish, then I would recommend you don't switch to a Thinkpad as you will find probably find the WHOLE screen disappointing. Lastly, I think this probably goes for most Wintel laptop manufacturers.

I can not stress this enough. The thinkpad is HORRIBLE at color reproduction. I bought one after returning my MBP and promptly returned the Thinkpad and ordered a MBP again.

The screen on my Thinkpad is bright and uniformly lit with uniform color rendition. The screens on the two MBPs I returned did not have uniform color rendition since the bottom of the screen caused whites to look yellow. Color reproduction can be improved by using a colorimeter to establish a color profile, but it won't work where the screen does not reproduce the same color uniformly. That's the problem I experienced with the MBP with LED backlight. You should have tried to calibrate the screen on the Thinkpad.

Thanx ... I will,
I don't really remember but I think I developed one of the calibration file posted in this forum ... I have to search again to give the credit to that person :)

Thanx ... as far as I remember, I didn't say anything to the genius bar at apple store... but ... my case was kind of weird ... i was fighting with both apple store and tech support :D i wanted to take it to the store for repair, but since they didn't have the part in store and took them so long to order one, I changed my mind to send it to tech support. I am 100% sure that I asked them several times to change it with a LG. exactly 1 hour after I hung up with tech support, I received a call from apple store stating that the part arrived !! lol ... I canceled my order with tech support and took it to store

so ... maybe they left a note on my case number :confused: or maybe I was lucky ... cause the genius bar ordered it couple of days before my request for a LG screen.

another possibility : the store ordered more than one LCD, and when they saw the note on my case, decided to replace it with a LG.

The whole point is, we don't want a luck of the draw sort of situation
going the repair route. More than a few people went the repair
route and ended up with another sammy or 'within spec no repair done'.
So if there is anything to do to ensure LG going the repair route, that's what we want to find out.

Thanks for the info!

I did try calibrating it.

Which model/screen do you have?
 
I had a really bad repair experience.

They changed the screen, but the tech clearly made the job quickly without inspection. By that I mean that the screen not properly aligned with the computer, causing the lid to be hard to close and open, and one of the two "clip" that hold the screen when close was not fonctionning. Also, apart from beign ugly when closed, it "stress" the componen, shortening their life.

Anyway, the new screen was a samsung yellow too, so i'm waiting for the replacement to come and I won't have to live with the bad repair, but just seeing how bad the repair was and the total lack of attention to details is enough to convince me that replacement is the way to go.

I don't have pictures, but here's a "photoshop image" that is clearer.
 
I need to check makes, but...

My first run, ordered the-day-it-came-out SR MBP had ZERO yellowing and perfectly consistent brightness.

Due to an accident which was my fault, that screen got totally trashed and I had to have it replaced.

New screen? Zero yellowing and perfectly consistent brightness. It's probably the best looking laptop screen I've ever seen.

Are you exaggerating the misalignment? It's impossible for your to close the lid with such big misalignment

Thinkpad X60 with a Samsung screen. It looks much better than the two MBPs with Samsung screens I returned. I intended to use a MBP in addition to the Thinkpad, which is my travel computer. I wanted to use it for photography, among other things. But I wasn't willing to pay $2500 plus tax for a screen that was unevenly lit and yellowish on the bottom. Also, text looks much clearer on the Thinkpad. This was my first experience with Apple computers, and I was disappointed. I still monitor this forum in the hope that Apple will do better. It was fun learning a new operating system, even if I only had OS X for less than a month. :D

My T60 also has a Samsung screen: 14.1" SXGA+ (1400x1050)
I don't have a calibration device so I have tried calibrating it with freeware stuff. Most of these attempts did not really work out, and can only be attributed (as far as I can see) to the quite average quality of the LCD. I should also mention, however, that I have yet to find a free Windows color calibration app that is of good quality (e.g. SuperCal for Mac).

Having just picked up my 15.4" MBP today and calibrated it with SuperCal, I am proud to say that it is:
- Week 38 build
- 9C67 screen (LG)
- No yellowing (slightly darker at bottom, but mostly due to viewing angle)

This MBP screen has desktop LCD quality brightness and black levels and amazing colour saturation (but that was the same on my 12" iBook G4). Side-by-side, the Thinkpad with Samsung just seems flat and dull. If anything, the MBP LCD has a tiny tiny bit of grain to it (or I could be imagining it).

I have to agree with you, however that the Windows fonts do look sharper (with Cleartype on and tuned with Cleartype Tuner). That could be because the Thinkpad has a slightly higher pixel density (124ppi vs. 110ppi). However, Cleartype generally seems to have more conservative anti-aliasing (and yes, I have fiddled with the Appearance Pane in OSX).
 
I just got an MBP with a 9C66 screen. It has the yellowing issue. Anyone know who makes the 66 screens? Maybe I should try SwitchResX.

Perceiving Windows fonts as sharper might indeed be related to the ppi in Lividity's case, however, I am unsure whether approx. 15% difference in ppi is recognizable.

Most likely the issue relates to the different rendering philosophies used in Windows and OS X, cf http://damieng.com/blog/2007/06/13/font-rendering-philosophies-of-windows-and-mac-os-x

Basically OS X tries to render the font's size as correctly as possible which results in a slightly more blurry appearance for some font sizes. Windows on the other hand distorts the font size to allow for better rendering at any given resolution.

I can see the point that design professionals would prefer OS X for obvious reasons, however, it made the process of switching from XP to OS X slightly awkward with regards to text display. Nevertheless I am as happy as I could be now on OS X and hat the XP machines at work...

Cheers,
Dembo
 
Second one here too, also a week 40, glossy samsung. There's also a little lip on the edge of the top case.

I'm sorry to hear that, i also got the 9c66 but i'd say it has no yellowing, even though when you use the 2 images for a test, the bottom square is not as bright as the top one (even looking from different angles), but i was concern that maybe that still was a defect, so i compared my screen to a friend's one (which was a 9c67) using the images, and the result was the same, actually his was probably slightly worse from this point of view (but i must say that the color gradient on his LG is better than mine).
I also run the test on a friend's mac which is a powerbook G4 and again the 2 white squares were not identically bright.
The only mac that i tested so far where the 2 squares are 100% identical is a iMac that i use at work, so i wonder if that is a common problem of laptop lcd...
So i am sure that out there someone has really a yellow bottom, but i am also wondering if anyone is actually confusing the yellow bottom with this other problem...getting 3 or 4 replacement it's crazy and i understand very frustrating!
 
Are people getting any better luck just going to the Apple Store and demanding a replacement unit instead of repair? (unless return policy is still in effect...)
