So many people confused about 4K since TV manufacturers started marketing the term. 4K's been around since the early 2000s (2001 or 2003 I think) so nothing new really
4K isn't unnecessary at all, it all depends on what purpose it is used for. for a monitor 4K resolution has a clear advantage over 1080p or 1600p. Especially when it comes to graphics design, photography, video editing, playing PC games etc. You'll sit much closer to a 31" 4K monitor than you would a 32" TV and watch TV/movies.
When it comes to TV, you don't really need 4K until you have a large screen, really large screen. We're talking a minimum of 70 inches before the benefit of 4K start to kick in. But as some one using a 1080p projector on a 106" screen and only sitting 10 feet from the screen, I can tell you 4K isn't NEEDED, even this close to such a large screen 1080p is sharp. 4K would still significantly improve my image though.
Digital cinemas use 4K but remember the screens are like 40-60 feet wide. 50" 4K TVs are useless.
I've seen the VW1000ES project 4K images in a black masked room on a 129" screen, there's nothing that can visually compare to that experience
