Xbox One S doesn't display 4k on Normal Blu Rays it converts 1080p

Xbox One and Xbox One S are 1080P Gaming

Xbox One S will play 4K Blu Ray's

Xbox One X will play Game in 4K if they are Enhanced with 4K Support + 4k Blu Ray support

They Xbox One X will also Upscale on a 1080p screen so you will see some benefit of the Xbox One X

Hi there,

let me try to answer your questions.

1 and 2. Yes it can play 4K Blu-ray discs and Yes when set to 4K output it will upscale the content. See this snippet from the support page: "When you set your console resolution to 4K UHD, everything on the console—Home, games, and apps—will display at
4K. 4K content is displayed in its native 4K resolution, and other content (like 1080p content) is upscaled to 4K."

This is the link to the support page with the information:

I recently tried watched The Force Awakens on my xbox one s rather than my blu ray player, and i must say, i was absolutely impressed with the blu ray upscale. Although keep in mind that it was connected to an Hdmi port that supported UHD color on a 4k Samsung
Tv

Unfortunately no. And an Xbox One S won't give you 4K gaming either. The Xbox One S only does 4K (with or without HDR) for video streaming or 4K UHD Blu-ray.

Games on the original Xbox will only play in 1080p and the maximum streaming quality for the Xbox App on Windows is 1080P anyway. Because your laptop's display will be 4K or 3840x2160, games will display in that resolution, but it will be an up-scale, not
a true 4K feed. Some games may look better, but you're not getting a 4K experience. That will only be a achievable on the up-coming Xbox X while connected via HDMI to a 4K screen.

I have noticed that since either the latest system update (or possibly Blu-ray app update), normal Blu-ray movies don't upscale to 4k anymore. They only stay at 1080p. I've tried everything, and it only stays at 1080p.

As soon as I go back to the dashboard or play games, it'll revert back to 4k. But as soon as I put a Blu-ray in, back to 1080p. And it was working beautifully before the last system update (the one that released on the 5th August), and Blu-rays all upscaled
to 4k.

This needs looking in to MS.

Xbox One S is not really a 4K console,

4K Media Content - Yes

You can play 4K Blu-ray DVD's or Streaming services like Netflix in 4K just fine if your paying the the 4K subscription options,

4K Gaming Content - No

As for games, it only plays games at 1080p but it is upscaled to 4K, other wise a 1080p image without upscaling to 4K, will look much worst on a 4K screen than what it would do, if it was only displayed on a 1080p screen,

A 1080p image upscaled on a 4K screen does look a little better than a 1080p image on a 1080p screen, but it still a 1080p image made to fit a 4K resolution screen, which is what the Xbox One S does

Xbox One X is a 4K console,

4K Media - Yes

4K Gaming - Yes

The issues is not the TV, it's the Xbox One S not being an Xbox One X.
