I remember when they started HD. I bought a 65" HD TV when they first came out. PBS had a four hour loop of HD that was beautiful. But after you watched it a few times, it got old. Then that fella in Dallas (Mark Cuban)started a HD channel on Dish and it soon got boring also, because there was not just that much video available. So, with 4K, be patient, it will take a while for much programming to become available, if ever. Since it is not mandatory, it may never be mainstream. That is a problem with being on the cutting edge of technology.
