Question: how much 4k tv content is available?
Answer: After a slow start, there are now well over 500 titles (new and old) available in 4K. Discs that can handle resolutions up to 3840 x 2160 and up to 60fps (frames per second) are classed as Ultra HD, and the format also supports high dynamic range (HDR) and object-based immersive sound such as Dolby Atmos and DTS:X.
