I don't know man, you sound rather paranoid to me. You can take this for what its worth: I don't care about Samsung or LG or Apple. I'm just a consumer like you. I don't work for any of these companies and no company that is associated with them. Go look through the posts. I've seen several people say they had to return their Samsungs because of yellow tints and some had spots and light bleeds. Again, here is my position so you will understand.
1. As reported here, there seems to be IR on many LG screens and some seem to have it worse than others. Regardless of claims on this thread, we really do not know what percentage of monitors have it except for unsupported speculation. I have also agreed that regardless of Apples' claim, that IR is definately a problem and not normal.
2. So far Samsung screens don't exhibit IR, but some have said they have had yellow tinted screens and some have had bad pixels come up in a fes days and various light bleeds. They seem to have different problems than the LG's but also many who have the Samsungs have reported they like them and have no problems.
3. I have suggested that if you have already passed the 14 day window that you report the problems to Apple so they know they have a problem. Then stick around and find out when they actually have a solution.
4. I have also said that it seemed to me to be counter-productive to play the screen lottery because so many of the people on this thread who have now gone through 2, 3 or more screens and are still having problems.
5. I have also said that my LG screen has some IR but it hasn't gotten worse and has not prevented me from doing anything including the photography post-processing that is one of the main uses of the computer, but that I'm watching it carefully.
6. Should it get worse, I will work around the IR and will probably wait a few months until I know that I will get a decent screen regardless of the maker of the screen and give Apple and its suppliers time to engineer the proper solution. I admit I may be naive that Apple will try to solve this, but in using Apple for several years, I've seen problems happen and get handled over time, always, so I believe they will fix this situation.
Now is that so bad? Do and think what you want. But attacks on me for having a different opinion than you is just bad form.
