All 15" LED MBPs Have Yellow On Lower LCD?

[kolax]

My first SR MBP had the yellow issue so I got a replacement. This one has no yellowing at all.

If I load a completely white background, there is a variation in brightness between the top and bottom (only noticable) but I don't notice it at all for every day use (browsing web, email etc).

I'm willing to bet that it has to do with the viewing angle. Probably because LCDs are only good when you look at them straight on, and when you're looking at the top of the screen straight on, the bottom is going to appear slightly differently. The LED backlighting gives it a yellowish hue instead of the blueish hue of the old ccfl backlit displays.

I know that some of the MBPs did have real yellowing on them, but some of more subtle yellowing could be caused by this.

I don't think so. If your MBP display is yellow at the bottom while looking straight at it and you turn the display upside down, the yellow will be at the top. It doesn't seem to be the viewing angle that's causing this.

I keep looking for a yellow cast at the bottom of the screen of my new MBP, but I can't find it. I still think it must be there, since everyone else seems to have it. But sadly I can't see it.

You mean luckily you can't see it.

Put my MBP (LG panel) in the "no yellow tint" camp. It's been discussed so much that I sometimes look for it, but it's never there.

before I brought my mbp home I booted it up to check for defects...I examined it under a microscope for a good 20 minutes (I went at a quiet time and did this near the genius bar). I could not find one single flaw with the laptop (while paying particular attention to the screen). After using it for a few days, I began thinking that the bottom of the screen looked a little yellow. if you do a search ("What do you think of this mbp screen?") I posted some pictures and it's 50:50 as to whether I have the issue. Honestly though, if I do it's extremely subtle and people suffering from the defect must have screens that are MUCH yellower (to have caused such a fuss about the screen). I still don't even know if I have it - so I'm just happy with my machine.

And to say that all mbps have the defect is a ridiculous statement...if the yellowing was on all models the engineers would have surely noticed it and fixed it before making 10000 of them lol.

I've had a chance to look at some more MBPs. I finally realize that my MBP is within spec for a SAMSUNG display. I took mine to the store and it matches the 2 other Samsung displays at the store. This made me feel good and bad. The good is that at least Samsung is consistent with themselves. The bad is that they all seem to have yellow. Now as far as the LG machines, I did notice that they do NOT have the yellow.

Let me change my statement from all MBPs have yellow to all Samsung MBPs have a yellow at the bottom. It is indeed very subtle and the average joe may not notice but it's there if you look hard enough. take two safari browsers and put the address bar of the one at the very top and the address bar of the second at the very bottom.

Now that I know that I have a machine that's within spec, what should I do. I do want a LG but don't know if it's worth it. I did like the warmer tones of the Samsung. I suppose the LG can be calibrated to be warmer? Also, I think I saw a slight uneven lighting on one of the LGs. The other one was pretty much perfect.

If I return it, I may get another Samsung with the same thing as what I have now. I may get something worse since mine is not that bad. I also have to wait another two weeks and it's a hassle for something that may not be resolved in the end. What should I do?

I also have a Samsung screen and as I mentioned in an earlier post, I do not notice the yellowing with day to day use. Only if I run one particular test do I notice the issue. I spent a long time deciding what I should do and came to the conclusion that I was not going to change mine. I do not know exactly what the odds are of getting another Samsung as a replacement but even some of the LG screens have still had the yellow problem. I did not want to go through the hastle and get a replacement which was even worse and then have to go through the problem of multiple replacements like some people have had to.

I think I am in the same boat as you. I am thinking I will stick with mine as it's barely noticeable and I wonder if I would have even noticed if it wasn't for some of the posts on this forum. After going to the store, I think I have a 'normal' MBP. The two Samsung screens at the store were identical to mine so that makes 3 identical Samsung screens. I doubt anyone even notices at the store, even the employees. I think the huge hassle for no gaurantees to a perfect one are just not worth it. I'd rather just be happy with my MBP
