My bedroom T.V. where my Nintendo Wii U is connected is 720p. My Living Room T.V. is 1080p, mostly for family TV viewing and when I have friends over, I'll just connect my Nintendo Switch.
Well at least I know I'm not just part of a small group of people that are stuck with 720p lol. Went on /r/Forza and it seems like almost everyone there has 4K, or at least 1440p.
