I just bought the new Xbox One X which has 4k blu ray player built in. Has anyone else jumped on the 4k wagon yet? I've been doing a lot of research to see if the additional cost of 4k blu-ray vs. standard blu-ray and it sounds like in most cases the answer is no because the majority of movies are still mastered in 2k. I was curious as to what others who have tried the medium thought about it. I'm really tempted to get the new Nolan 4k collection since his films are mastered in 4k.
I was actually thinking of picking up an Xbox One S which also has a 4K bluray player with it. Couple that with the tons of TV deals you see for 4K TVs esp 55" I'm thinking of taking the plunge soon. However, the content availability right now for 4k material (whether on physical discs or streaming) is definitely not comparable to 1080p material. In addition to that you get great deals for regular bluray even though I do see 4K content becoming available for a lot cheaper than before.
The other reason I was thinking of taking the 4K plunge is that it will play regular 2K content and people have sworn that it looks a lot better on a 4K TV compared to the previous 1080 resolution.
Since you already have the player, if you do get a good deal on a TV I'd say go for it. You'll be able to play both your content on the 4k TV.
