I have a 4k television, but something still troubles me. For instance, hypothetically, say there's a breakthrough in manufacturing costs for 4K televisions, and they can be bought for a relatively reasonable cost. Also, assume at the same time entertainment companies have lots of material available for streaming and/or download. How are you and your neighbors all going to be able to stream huge ultra HD files at the same time when physical bandwith infrastructure is limited? This isn't meant for any person in particular, just a general question.
