4K Ultra HD Blu-ray™ and Streaming
With four times the resolution of standard HD, 4K Ultra HD delivers the clearest, most realistic video possible. Stream 4k content on Netflix and Amazon Video and watch Ultra HD Blu-ray movies in stunning
visual fidelity with High Dynamic Range.

Although both the Xbox One S and the Xbox One X can both stream 4K, only the One X is capable of true 4K gaming. I would recommend the XBox One X over the XBox One S because it only one that can truly do 4K gaming! The XBox One S can upscale 1080p games
to 4K but isn’t a real 4K console, although it can play Blu-Ray in 4K. The XBox One X is the first console to truly be able to stream 4K gaming, plus it has a Ultra HD 4K Blu-ray player!

I only have one 4K Blu-Ray Player. It's my Xbox Series X.

Hey, I just bought the XB1S solely for 4K Blu Ray, but I seem to be having the same problem.

My TV
(here) is a 4K UHD TV and while I have the 1S connected via the provided HDMI cable, it won't acknowledge that it's even capable of displaying at 25/30Hz.

Want to know what's going on here, pretty annoyed because I only got it to replace the current bluray player for 4K.

Hi,

Several reasons.

1. The 360 has a DVD drive. Full HD discs use Blu-ray disc tecnology. 4K Ultra HD use UHD Blu-ray discs. The 360 can not read Blu-ray discs.

2. The internal 360 hardware is simply not fast enough to decode 4K video content, and the graphics hardware can not output to 4K anyway.

No software in the world can update old hardware.
