I keep the brightness down all the way (in fact if anyone knows how to make it even lower, I would greatly appreciate it) and it does not bother me in the slightest. Maybe this is a difference of opinion, or possibly some hardware has it worse than others?
Question is, how are people's backlights doing? Mine gets a bit darker on the right-hand side - starts getting dark about 1/2-inch away from the end of the screen, and the bright points from the LEDs are noticeable. Overall its only annoying when viewing bright solid colors, and I'm probably only noticing because I'm really picky - just wanted to know if anyone else's 770 has that.

Mine too. Eh. Nature of the beast. Really doesn't bug me.
