Thanks, the audio instructions on the disc weren't as clear to me. I referred to the booklet and it was much more clear about this.
I'm still confused as to why the overall screen brightness gets darker when more bright is on the screen, though. For example I'm playing "Bit.Trip Runner 2" on my Wii U. It is a very bright and colorful game, and looked so on my LCD. now playing on the VT50, it looks dull. When I pause the game and the dark pause menu covers the right half of the screen, the visible part of the game to the left becomes bright, as it should be. Same goes if I press Menu on the TV remote which covers the left half of the screen. How can I get this level of brightness when the whole screen is bright?
