A:Answer This generation of upscale 4K player will make your Blu-ray movies look very good at "near 4K". It is not actually display true 4K – that is the next-generation players which will be coming out in a few months, assuming at a premium price.
I was playing Harry Potter blu ray the other day, and it froze the scene, and I stood about a foot away from the TV (65 inch 4K that I bought from Cosco), and it simply looked amazing. Keep in mind that there are no real 4K Blu-ray movies available now and when they come out, it will not play on this machine. Those "4K Blu-ray" movies that you see are mastered from 4K source.
