i have some issues with black, but only noticable when you really look for it. Other than that it's perfect product, and beautiful screen, no dead/stuck pixels.
 
To answer some questions:

The first TWO characters are the FACTORY. The 3rd character is the year of production, which should be 7. So, all iPt made in factory 9C would have the first three characters as 9C7. The next two digits are the week.

Mine is: 9C740

9C factory
7 year
40 week


Understood?
 
I got a week 39 that came with 1.1, when I updated to 1.1.1 it mucked up the quality of the screen. Its got a very little bit of negative black but mostly everything looks bad quality for some reason, you can see little dots on the black parts of the screen... I've also got a lighter line all around the Earth on that default globe background...
I've noticed exactly the same issue :( The problem are artifacts, extremely well visible in black areas of screen. They look somewhat greenish. I've noticed that when you look at screen a little bit from left angle then this artifacts dissapear, and the screen looks much better, without this "greenish cast" that is visible when looking in front of screen.
So you're saying that with 1.1 screen looked better? If so, then it would mean that this is software issue that can be easily fixed with future upgrades, beacouse till now I thought it was hardware issue (bad screen) that cannot be fixed. Also, did you upgrade to 1.1.2? I would like to know if this upgrade fixes sxreen problems?
This greenish artifacts are visible on every ecreen, actually, even on my computer, but my computer's screen handles with this problem by "camuflaging" this greenish artifact with very deep black. On ipod touch, black is not very deep, it is actually too bright, that's why we see this artifacts. The problem could be easily resolved if Apple adjust gamma, brightness and contrast. In fact this settings should be implemented in menu....
 
I have a week 44 and it is off when I try the appleservedup tests. And it gets blown away by my 5-series screen iPhone.
 
My week 43(? starts 1a743...) looks perfect no pixels or negativee issues.

Im not sure if it looked better in 1.1 but I guessed its a software thing because all iPods over week 38 are ment to be fine. I havent updated because its jailbreaked and I dont want to have to put all the apps on all over again and do all the hacks and stuff I done on mine. If you havent jailbreaked yet or dont mind doing it again can you update and see what happens? A good way to test is to upload a album without any album art then go in to CoverFlow on the iPod and look at the quality before the update (it should suck) then look again after the update.
 
actually I haven't jailbroken, but I have updeted my ipod's soft to ver 1.1.2 and I see no improvement in screen quality. I guess they never gonna fix it :( Maybe they think that they totally fixed screen in ver 1.1.1 and there's nothing more to improve? Or maybe there's actually not much to be improved, because maybe it's a hardware problem :( I wonder does all ipod touches have this crappy screen or maybe someone have seen or heard of a good screen in ipod touch?
 
Second time in and they replaced my week 40. Negative black issues and cluster of dead pixels. Just got it today but I'm at work, will see it when I get home =)
 
Week 43 here.

Have gone with a watchmakers loupe searching for any "dead" pixels and none found!.

Simply perfect !. I love it. :)
 
I win screenwise. Passes all the tests and no stuck pixels... but software stability wise it's not so good.
 
oh dear lord, I can't believe this. I waited two months after getting one (week37) of the first negative-black-screen iPod touchs and yesterday I received my new 16 GB (week42) I bought off Amazon. It still has the bad screen and this time it can't even connect to Wi-Fi. It detects them but it can't connect to any of them.

I am seriously mad with Apple now. Not releasing Mac Pro isn't something I can complain about but having me buy two bad iPods in a two-month window is simply unacceptable!

I don't know if Apple Store will exchange something I bought from Amazon within 3 days it was shipped...I hope they do or I will probably wait for the 2nd gen iPhone rather than going through the whole Amazon send-it-back and try-this-one process. I am totally frustrated.:mad::confused::mad:
