Does apple TV dim after awhile?

I haven't had much time to troubleshoot this, but I've noticed that at times, my screen gets dimmer when using Apple TV. About halfway through a movie last night this occurred, and again shortly after. Is there a setting in Apple TV that would cause this or is it more likely a setting on my TV? It's a Vizio 37" LCD.

AppleTV shouldn't dim the output unless it's faulty.
It could be the movie encoding if it's bad but that's unlikely.
Most likely is your Tv has some automatic brightnedd adjustment in response to ambient light which is either faulty or getting altered by some change in the room.
Check your Tv mode options to see if it's on some preset that changes brightness in response to ambient light.
