To summarize the discussion thus far:
Is it possible to be lucky and to recieve a rMBP 13" without IR problems?
Or is it a fundamental problem present in each and everyone sold?
Again, You don't know that they don't ALL have the problem and maybe it shows itself at different times for people and even when it does, perhaps it's not noticed for people that simply use it for checking their facebook or twitter nonsense. So to say "Yes" to the first seems rediculous, unless you can point out something the rest of us don't know from reading this thread from the beginning. THE TRUE answer is maybe
For the second, THE TRUE answer is maybe.
What we know for sure based on this thread is the guys with an eye for this seem to be going back over and over with bad screens. That tells me its a serious problem that Apple isn't dealing with properly.
Does this mean that 100% of the screens will have a problem at some point? We don't know.
Maybe, 10% of the screens have a problem 5% of the people make their way to this thread.
Maybe, 90% of the screens are fine and obviously all those people aren't going to come here and write.
Maybe 100% of the screens are defective in one way or another IR, Tint, screen Mura etc. and only because they show their defect at different times we think it's not all of them.
Bottom line, we don't know beyond what people are posting about their experiences and making a definitive statement of "yes" and "no" to those two questions is false imo. However I'd be glad to read how you know definitively.
I think in terms of the Samsung (A01/A22) my experience with the new one is:
1. Color balance is really far off neutral. I'm not sure why this was done. It appears that the backlight color is quite pink (from the Apple logo) so maybe they've just overcompenstated with the screen coloring to neutralize that. I've had decent success in calibrating to neutral with my Spyder4 (see my previous post if you want to try plugging this profile in) but it's still not as true as it should be.
2. Brightness is very dim on the Samsung. I find myself using it anywhere from 4 notches from full up to full brightness. It seems like Apple could potentially release a software update in order to improve the brightness values for Samsungs specifically (maybe it's shared with the LG and thus is underdriving it) so that using it at mid setting is reasonable for typical use. Despite the brightness, whites do look pretty dingy. Not sure what can be done about this.
3. Creaks are gone. Much more solid build than my first. The bottom plate also has much smaller gapping between itself and body - I think this is why it's not creaking.
I think it's important for everyone to be realistic. It would be very difficult to say that ALL 13" rMBP suffer from IR. But based on whats floating around forums it seems that the issue isn't restricted to a bad manufacturing batch. It seems that something in the actual manufacturing of the screens needs to change or some quality control measure be put in place.
So logic would tell me that unless something changes over at the LG manufacturing plant all the screens coming off the assembly line will be affected by IR or whatever else. Makes sense, in any aspect of life, you need to make a change in order to receive a different result. No change means the result will stay the same. This applies to all things from manufacturing all the way to the person who wants to lose weight but hasn't changed anything in their lifestyle in order to attain that result.
On a more bright note, I have read here and on other forums that LG did put out a screen revision (not sure of the serial number or identifier) which people are reporting no IR.
JoshD: Thanks, I will be trying out your profile since you and I have the same screens.
The change was made for the 15"inch screens and they are still bad it just takes longer for the problem to appear. Still most screens divered with the 13" are still screens manufactured in 2012 so who knows if the later ones are better. No one have them so far. I think Apple is stuck with a really big quantity of bad screens and haven't sold much 13" until now because of the old high price. Of course they are not going to throw away all these screens even if they are bad so they keep shipping them crossing fingers for people to not see the problem which is what is happening now as IR is not something you naturally look for when you buy a computer and you are not aware of the problem.
M5Marco: Indeed it does. I think all the Samsungs have this. Their backlight has a slightly pink tint.
Here's something interesting, regarding the overall tint on the Samsung displays:
If you restart (which is a rare thing these days so probably why I didn't notice until now) you'll see that the apple logo screen is a pretty neutral grey. However, as soon as the OS loads it goes green/yellow. This definitely suggests that this is a profile/software issue. Is it possible just one profile exists for both the Samsung and the LG and it's incorrect for the Samsung? Or that Samsung is simply out of spec?
M5Marco: You can install the profile by:
1. Go to the Finder and open a new window
2. From the Go menu select Go to Folder
3. Put in "~/Library/ColorSync/Profiles"
4. Drag in the profile
5. Open System Preferences
6. Select Displays
7. Select Color
8. The profile should show up in the list under "Spyder Callibration 2" (sorry for the messy name)
Thanks a lot JoshD. I want to tag your post as having answered my question and solved my problem but I can't seem to figure out how to (so you'll have to make due with a "like" lol).
Interesting thing that happen as I chose your calibrated profile for the first time. I was so used to the slight yellow tinge to the screen that when I chose your profile the screen "came to life" with more vibrant color and sharpness, also the white seemed to have a more pinkish color to it. My eyes have since settled and I'm just seeing a whiter white.
*But let's all still hope Apple officially addresses the screen issues soon.
