A:Answer I did find out that my Uverse sends shows that are only 720p, so that's the best I can get over TV. I don't use the "smart" part of a tv, so it's a little disappointing believing I bought a 4K. It doesn't look like my boy friend's $1200 Samsung, but I didn't expect it to be as good as something almost $1000 more.
You do need to change the settings from how they have it when you first turn it on. I am satisfied with it now after spending days tweaking the settings. If you call them, they will teach you how. Then keep making adjustments until you're happy.
