Xbox One X 4K Gaming on a 4K UHD ( not HDR ) TV

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

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?

Hello Spinhead82,

Things are still in a state of change in the land of 4K UHD and haven't quite settled out yet. Part of this may have to do with DRM (Digital Rights Management) and trying to lock things down when it comes to all this 4K digital plumbing. Not only is it the
hardware, like needing to use HDMI 2.X cable. But, it's also the software. Does the firmware in the monitor/TV support the 4K UHD (HDCP 2.2)
content coming from the attached device ("Checking your TV's 4K and HDR capabilities on Xbox One S")? Yes, the Samsung U28E590D
can do 4K UHD, but does it support HDR10? HDR10 support seems to be a very important threshold when comes to connecting the Xbox One S to 4K UHD TVs. The current crop of 4K UHD monitors seems to be more directed to PC gamers. While, the Xbox One S is geared
more toward lager format TVs. I'm sure that this is not the only list, but Windows Central has what it calls "Best 4K HDR TVs For Xbox One S".

Good luck and good gaming,

I can say that my Samsung 4K UHD needed to have 4k activated in the HDMI settings of the TV. Also not all HDMI ports on all 4K TV's are capable of 4K.

That is correct, my Xbox is hooked up to HDMI port 1, which is often the only 4K HDR port (according to the Xbox One X user manual).

Yep. I think there will be a lot of dissapointed people when they find out their 4K HDR TV won't play Xbox One 4K games because they don't have a full 18Gig HDMI pipe.

The requirement from the X to have 4K @60 and 30 Bits just to play a 4K game seems off. I can see where the bandwidth requirement would be there for 4K @60 with HDR, but I'd like to play the game in either 4K without HDR or 1080P with HDR but the current
setup on the X (and S) will not let you do this.

Odd thing is that I played Horizons:Zero Dawn on my PS4 Pro and the first thing it did was tell me I could have either 4K or HDR but not both. I chose HDR and the game looks fantastic. I can't believe the XBOX One X won't do this.

So, if you have a display that does 4K@ 24 with HDR then the XBOX One X is just a nice game machine that will play videos in HDR for you but none of the UHD features are available to you for gaming.

Microsoft, surely you can change this and allow HDR in 1080P?
