“What do I need to do to get a better picture from my Uverse cable box? I've tried both a regular HDMI and 4K Cable and both come out at only 720p. I know this won't be 4K for cable, but I had 1080p with my 14 year old Samsung Plasma. Thoughts?”

First, check the settings on your box. It may be set to output only 720p. Next, call your cable company and ensure you're subscribed for 4K service, which you may or may not be. Finally, your box may not be able to provide a higher resolution than 720p. If that's the case you'll need a new box from your vendor.
