When I was choosing a new TV I was a bit concerned about brightness. 2000 nits is so much better (on paper) than 400 nits. But I wasn't planning on putting my TV outdoors and got a C2.

My current brightness settings are at 30% when watching TV at night. "Bright room" settings bumps pixel brightness to 45%, which is good enough for a room with windows on 3 out of 4 walls. It is much brighter then a 10 year old LCD it replaced. And I had no problem using that old one until I put two screens side by side.
