Troubleshooting 4K and HDR on Xbox One X and Xbox One S

If your Xbox and TV should support 4K and HDR but aren’t working as expected, here are some things to try.

First, make sure your Xbox and TV are 4K-capable.

• Make sure you have either Xbox One X or Xbox One S: On the back of your console, at right, near the network port, a sticker should show the model. If the sticker is missing, check underneath.
  
  Important Before turning your Xbox over, eject any disc and turn it off.
  
• Make sure you have a 4K TV: Refer to the packaging or manual for your TV. Different manufacturers use different names. Phrases to look for include:
  

• [table][tr][td]Names for 4K[/td][td]4K, 4K Ultra HD, UHD, UHD 4K, SUHD TV, Ultra HD, Ultra UDTV, 2160p[/td][/tr][tr][td]Listed resolutions or modes[/td][td]3840 x 2160 at 24 Hz, 50 Hz, or 60 Hz[/td][/tr][tr][td]Names for HDR10[/td][td]HDR Premium, High Dynamic Range, HDR, UHD Color, Ultra HD Premium, Ultra HD deep color, Dolby Vision[/td][/tr][/table]
  

• On your Xbox, check your TV's 4K and HDR capabilities: Press the
  Xbox button to open the guide, then go to
  System > Settings > Display & sound. From the
  Setup column, choose Video output > 4K TV details.
  

If your system should support 4K and HDR but it isn't working—for example, you can't select the 4K UHD resolution, 4K features aren't supported in the 4K TV details screen, 4K content won't play, or you're seeing video quality problems—try the following.

• Make sure the Xbox is automatically detecting your TV. Go to System >
  Settings > Display & sound > Video output. Under the
  Advanced column, choose Video fidelity & overscan. In the
  Display column, ensure that Auto-detect (Recommended) is selected. 4K isn't available when
  HDMI or DVI is manually selected.
• For HDR, check your TV manual to make sure your TV supports the HDR10 media profile. Look for support of BT2020 and HDR, or check the list above. (There are two HDR formats: Dolby Vision and HDR10. Your TV can support both, but it must at least support
  HDR10.)
• Make sure your HDMI cable is plugged into the right port on your TV. Some TVs support their full set of 4K features only on certain ports. Refer to your TV manual or try the different ports on your TV.
• Check your TV's settings menu. Your TV might have a special mode that turns on 4K or HDR. Refer to your TV manual to see if you must change your TV's settings. Again, your TV manufacturer may use different names for HDR—see the list above.
• If some content won't play, make sure your TV supports HDCP 2.2 and that it's turned on in your TV's settings.
• Make sure you're using the HDMI cable that came with your Xbox One X or Xbox One S.
• Try a different HDMI cable. Your cables must be certified for HDMI High Speed or HDMI Premium.
• If a device is plugged in between your TV and Xbox, remove it and plug your TV directly into your console with the HDMI cable that came with it. Some AV receivers or other video equipment may interfere with the data passed between console and TV. Your device
  must support the same capabilities as your TV, either directly or pass-through. Also, you must use cables certified for HDMI High Speed or HDMI Premium between both the Xbox and receiver, and the receiver and TV.
• Make sure your TV and AV receiver firmware are up to date. Many newer TVs and devices can take updates over your home network—if you find that it doesn't support some 4K or HDR features, a TV or receiver firmware update may resolve the problem. Check your
  TV or device manual to see how to update the firmware.
• If you're seeing a blank screen or errors while trying to play 4K content and you've tried all previous steps, turn off native 4K playback and try to play the content in a lower resolution. Go to
  Settings > Display & sound. Under the Advanced column, choose
  Video mode and uncheck the option to Allow 4K.
• If you're seeing strange colors while playing HDR content and you've tried all previous steps, go to
  Settings > Display & sound. Under the Advanced column, choose
  Video mode and uncheck the option to Allow HDR10.
  • If that doesn’t fix it, turn HDR10 back on. Then uncheck Allow Dolby Vision and see if that fixes it.
    
  • To learn more about what your TV tells the Xbox about its 4K capabilities, see
    
    Checking your TV's capabilities on Xbox One X and Xbox One S.
  • Dolby maintains lists of
    TVs and
    audio/video receivers that support Dolby Vision. Even if your device is supported, it might need a firmware update. (Note: These lists are English-only.)
• If you get an error when you choose 4K UHD in display settings, see
  Error when selecting the 4K UHD resolution on Xbox One S.

Getting a new TV won't solve my issue at all. My cable provider uses coax and not HDMI or cable box.

Well this new box does not say hdmi out but they gave me a cable to go into my tv from the box that's were I get confused if the hdmi port is being used to go from cable box to TV were I'm going to. Plug the Xbox ? I was expecting the new hd cable box
to have more than one hdmi port

Hello,

I have a new XBOX One and new 3D HDTV, and a Arris-Motorola MX011ANM X1 cable box from Comcast. I have not been able to get the Live TV to work. I have the settings, "Comcast" and "X1", but it's still on "Looking for your TV picture." I've tried 3 different
HDMI cables, that work on everything else that I've tried them with, and I've reset my cable box, but nothing works. Please let me know if you have any suggestions.

HD component cables for my cable box into my TV and the HDMI for my cable box Into the X1 so I can watch it with or without the X1. My surround works perfectly when watching TV through the X1 with this set up.
