Everybody Needs 8K

Both Samsung and LG were showing huge 8k displays (Samsung's is shown here) and drawing crowds (I couldn't get near enough to LG's to shoot a photo!). While clearly technological demonstrations (with 16 times the resolution of 1080p "Full HD,") someone in Korea thinks this would be a nifty idea. But on the size sets most people buy, I'm not at all sure, apart from the Wow factor at a CES.
