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....
