So I read a thing yesterday that said Chrome doesn't play Netflix at 1080p. I hadn't really noticed, honestly, but sure enough... It usually goes up to 720p. After fiddling though, I couldn't get it to go to 1080 on ANY browser, even though my buffering and bitrate is at the max, and my download speed is 60mbps+.
Mucked with some of the settings, tried "high" instead of "auto"... Nothing doing.
EDIT: Solved. Win7 is not supported for 1080p for Netflix.
