4K UHD Disc?
It seems every decade there's a new, higher-resolution format to replace the previous one.
I won't be replacing my entire blu-ray collection with 4K UHDs, but there are a few movies that I was very impressed with the look of in cinemas that fell short in color dynamic range on blu-ray, that merit 4K UHD, like The Martian and Mad Max-Fury Road. Thankfully, the 4K UHD release INCLUDES a blu-ray as well, so, for a few extra bucks, present and future bases are covered.
What do you think?
