UHD Bluray won't play in 4K on 4K non HDR TV

you need hdr for 4k output

Actually, you don't.

Uhd and hdr are required for 4k output

You need UHD, in the sense that you need the TV to support 3840 x 2160 resolution, but you don't need HDR enabled to reach 4K. UHD 4K is the amount of screen resolution available measured in pixels, HDR is the ability of the TV or monitor to display more
natural colours.

Note that the Xbox One S can do HDR in games that support such a feature, but regardless of what resolution you set, all games max out at 1080P internally. If the display is 4K, it will remain in 4K, but games will only be upscaled. Only the Xbox One X
can play Enhanced titles in 4K natively.

You should be able to disable HDR, how you disable it depends entirely on your TV. Disabling HDR via the TV settings should not disable 4K screen resolution. Indeed, some Xbox One games do not support HDR, Fallout 4 on the One X can play in 4K for instance,
but it does not support (or indeed have an option for) HDR.

On my Sony Bravia Android based TV, I had to go to the main settings and enable HDR functionality. Even then, I had to set the HDR setting to 'Auto' on the HDMI port I have my console connected to. If you have HDR set to 'On' all of the time, non HDR games
will display the wrong colours, look oversaturated. With 'Auto' enabled, HDR will only operate when it detects an HDR supported game. This may not be a feature of your display however.

What make and model is your TV?

Thanks for the reply. Will do. I was really glad that the xbox 1 read the 4k disk as my panasonic is a 4k upscaler and wouldn’t read it. It runs the uhd disk fine and all gaming in 4k hdr. Sweet, but was dissa-ointed at the dvd playing as my panasonic scales
them to 4k and they look better that alot of blurays.

cheers.

Skyrim won't be 4K, it's basically running an updated engine with new graphical effects at 1080p - Think Skyrim with Fallout 4 visuals. So will Skyrim look nice? Absolutely yes, no question. If Skyrim supports HDR, which it most likely will, then yes,
it would look better on a HDR supported TV. As far as I've seen HDR is only on 4K TV's, I have not seen it on 1080p displays. HDR is a hardware display technology, to see HDR, you'll need an HDR TV and the content you are watching or playing needs to be
HDR.

The Xbox One S's 4K abilities are only confined to video playback via from UHD Blu-ray or 4K capable streaming.

3. Yes you will need a 4k HDR tv to enjoy HDR, I dont think they have released non 4k tv's with HDR

you need hdr for 4k output

I don't think you fully understand

Uhd and hdr are required for 4k output

Unless you have an xbox one s not a x

You can't play in 4k

4k is only for.movies or streaming sources which require both uhd and hdr

But.xbox.one x will do 4k gaming
