That’s my point.. I don’t have a tv provider.. I get all my channels through this buzz box. 

But the live tv through the antenna is also exceptionally clear and crisp. Only the shows through the box are not HD quality. 

Thanks for your responses....Netflix, Prime, Apple and Disney, Youtube are all very clear GREAT video quality but the shows on buzz box are not sharp...a bit grainy.  I thought it was 720 quality but can not find a place in settings to verify.  1080 would be much better.  The only change I can find is size of screen.

I talking regular tv channels such as abc nbc cbs… all of the channels are not great video quality. 

I had the 4500 but the picture is not best quality. Grainy. Tv is 4K. Is there a setting I can’t find?
