I’m pretty much in the same boat, 720p looks fine to me in the vast majority of cases, and while I’m not great at going to my eye doctor regularly, the last time I had my vision checked it was fine, and it was right around the time I was shopping for a new TV and upgraded from 1080 to 4k, and still had a 720p in my bedroom.

If I looked really hard at them, I could tell the difference from the 720 to the 4k, but truth be told, I’m just not scrutinizing the picture quality of my TV that much.
