Xbox One S, how to stop blu rays from upscaling to 4k

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:
support.xbox.com/.../4k-on-xbox-one-s

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

"Ultra HD" Blu-Rays will play in 4K. Standard Blu-Rays will play in 1080p.

The Xbox One S will only output to the highest resolution offered by the Blu-Ray disc it plays.

I suppose this design choice was in mind because 4K/UHD-TVs already process and upscale a lower resolution image to "cleanly" use all of the 3840x2160 pixels, so it's not putting unnecessary load on the Xbox One S CPU.

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!

^ hey, thanks for replying and thanks for sharing your experience. glad to hear I'm not the only one.

yeah. it's frustrating. and on top of this issue, I just learned that the S really doesn't upscale regular Blu-Rays to 4K, despite what MS says on their official support page - they say everything is supposed to upscale to 4K when you set the S output
to 4K UHD. But apparently, that's not the case with regular Blu-Rays.

so, yeah, 2 issues that are frustrating and disappointing.
