4K Blu-ray playback

several new release Blu-Rays are coming mastered in 4K so its time the Xbox One did an update to support the playback. I have a 4K tv and dont want to pay out for another blu ray surround to get 4k support when the Xbox could and should support playback..its
only firmware afterall isnt it?

It doesn't support 4K UHD playback.

If you are referring to "Mastered in 4K" discs those are just 1080p titles made from a 4K master.

New hardware is required to playback UHD Blu-Ray.

Not sure about the sync issue, but the Blu-ray app on my XB1 S keeps wanting to update every time I go to the update section in "my games & apps". And also 4k playback isn't working.

It seems the latest console update messed up the Blu-ray/video playback in many areas.

You are misunderstanding the "Mastered in 4K" on some Blu-rays, Rcbynature. It doesn't mean the Blu-ray disc itself is in 4K, it means that the master the disc was made from is 4K.

No current Blu-ray can hold the data required to store an 2 or 2+ hour movie in 4K. All Blu-ray discs on the market are no more than 1080p resolution.

Native 4K Blu-ray will require new playback hardware as no player currently on the market is compatible and in fact only prototypes have been shown at trade and electronic shows.

There ARE some streaming options such as Netflix and Amazon Prime, but those are in restricted markets and require a very robust internet connection in all cases.

Updating the Xbox One is never going to happen firmware or otherwise. It simply doesn't have the hardware to support 4K playback.

Before someone comes back with "but the HDMI cable that came with the Xbox One says 4K capable, ANY high-speed HDMI cable is 4K capable at the 4K resolutions used so far. 4K @ 60 frames per second will require more bandwidth going forward though and the
HDMI chipset version has already been revised to HDMI 2.1 to accommodate that throughput requirement.

Hey there mind if i jump in here!

As i am aware not all HDR / 4K supported movies work on the Xbox one S at the moment (Some bug out as you mentioned while others crash the Blu-ray app) first lets head over to the settings - Disc & Blu-ray - Blu-Ray - Persistent storage - Clear persistent
storage

As well double check if your settings are correct for full Blu-ray playback.
