My screen wasn't bad-- I've seen several 770s, several at work, and a few family members had them. They all had the same traits-- and if you didn't notice it, it was only because you didn't have anything to compare it to, or are not as sensitive to those types of things because they all exhibited those shortcomings.

The two or three 800s I have seen now are all vast improvements and the screen itself is obviously a different (better) unit.
