Check the prices of the 4k dvd players; you can almost get another 4k tv for the cost of the dvd player. Wally World sells a limited selection of discs. If you have a Roku 4 or similar, there are a couple subscription stations out there. Oh yeah, you know they are working on 8k tv now. Can't win.We just got a 4K tv so I need to get some 4K content.
Edit to say, watch out for dvd players that say 4k compatible, that just means they work with 4k tv's (don't they all?).
