If I'm going to be honest, I don't even have 1080p. Planning to something new soon though.
Gotta keep selling TVs, right!? When everyone has 1080p and 4k, what else will you do? 3D was a flop and 120 Hz got nowhere. The HDMI group makes LOTS of money when you buy new cables and TVs. That's why it also take a new cable, by the way.
