Xbox One X outputs 4K and HDR only when the console, cable, HDMI port, and the TV’s enhanced-input mode all match — then you set 4K UHD in Settings.
Half the 4K complaints on an Xbox One X trace back to a television menu, not the console. The hardware is ready for it — 2160p frame buffers and 6 teraflops of graphics power — but it only pushes 4K when the cable, the HDMI port, and the TV’s enhanced-input mode all agree first. Working through how to set up your Xbox One X for 4K and HDR display settings means checking four links in that chain, in order, and the console will name the one that broke.
The whole check takes a few minutes, because the 4K TV details screen on the console reports exactly what the television is telling it. Here’s the order that works.
What The Console, Cable, And TV Each Have To Support
Four links have to agree before an Xbox One X outputs 4K and HDR: the console, the HDMI cable, the specific input on the TV, and the TV panel itself.
Xbox One X supports 4K gaming at up to 3840 × 2160 and reports 24 Hz, 50 Hz, and 60 Hz modes at that resolution. HDR requires a 4K TV that supports HDR. The original Xbox One can’t do 4K gaming at all, while the One X and One S can both display HDR content.
- Cable: the HDMI cable in the box is enough. If you need more length, buy a High Speed or certified high-speed HDMI cable.
- Input: some TVs carry full 4K/HDR bandwidth on only one or two HDMI ports, and many ship with the enhanced mode switched off under labels like UHD Color, Deep Color, Ultra HD Deep Color, Enhanced format, or Input Signal Plus.
- Panel: TVs sell HDR under names such as High Dynamic Range, HDR10, or Ultra HD Deep Color, and a firmware update sometimes adds the feature a model shipped without.
If the TV is the part you haven’t settled yet, this tested 4K TV roundup for Xbox One X sticks to panels that hold 60 Hz on every input.
Xbox One X 4K And HDR Setup: Ports First, Then Settings
Plug the console straight into the TV first, switch on the TV’s enhanced input mode second, and touch console settings last.
- Use the HDMI cable that came with the console and run it directly to the TV. Skip the AV receiver, soundbar, switch, or capture card for now.
- Move the cable to the TV’s 4K-capable HDMI input, then turn on that input’s enhanced-bandwidth option in the TV menu.
- Press the Xbox button, then open Profile & system > Settings > General > TV & display options.
- Set TV connection to Auto-detect if your resolution isn’t listed.
- Choose 4K UHD under Resolution, then pick the refresh rate the TV reports.
- Under Video modes, turn on Allow 4K and Allow HDR10. Turn on Allow Dolby Vision as well if the TV lists it, and leave HDR10 enabled alongside it.
You’ll know it took when the screen blanks for a second, 4K UHD stays selected, and 4K TV details shows green checks for 4K 10-bit and HDR10. Keep in mind that 4K and HDR still depend on the game or app — a 4K dashboard doesn’t make a 1080p title render at 2160p.
| Setting | What It Enables | What It Needs |
|---|---|---|
| Resolution: 4K UHD | Games and apps drawn at 3840 × 2160 | A port reporting 60 Hz, or the console refuses it |
| Allow 4K | 4K output for supported games and video apps | A 4K-capable input and a suitable cable |
| Allow HDR10 | HDR10 color and brightness on HDR titles | A 4K HDR TV with enhanced mode on |
| Allow Dolby Vision | Dolby Vision in apps that support it | A Dolby Vision TV; keep HDR10 on too |
| 4K TV details | A check-by-check list of detected features | Reading it after every change you make |
Why Does Picking 4K UHD Give A “That Didn’t Work” Error?
A That didn’t work message means the console found a 4K signal but not a 60 Hz one on that input, so it won’t upscale system software, games, and apps to 4K — though it can still play 4K content at other refresh rates.
Four causes cover nearly every case:
- The cable sits in an HDMI port that isn’t 4K-capable.
- The TV’s enhanced HDMI mode is off for that port.
- The cable is too old or too long for the bandwidth.
- Video passes through a receiver, soundbar, or capture device that can’t carry 4K/HDR.
Each fix is a swap, not a settings hunt. Xbox Support’s 4K and HDR troubleshooting steps walk the same order if the message keeps coming back, and a TV firmware update is worth checking before you buy anything.
Run the chain once more, in order: direct cable, 4K input, enhanced mode on, Auto-detect, 4K UHD, Allow 4K, Allow HDR10. Any yellow warning on the 4K TV details screen points at the exact step that failed, which saves you from replacing hardware you didn’t need to replace.
Common Questions
Is The HDMI Cable In The Box Good Enough For 4K HDR?
The cable that ships with the console handles 4K and HDR over a direct connection, so no upgrade is needed. Replace it only if you need more length or the picture drops out, and then buy a High Speed or certified high-speed cable. Long, thin, unbranded cables are the usual cause of flickering at 4K 60 Hz.
Does Xbox One S Output 4K Too?
The One S outputs 4K for streaming video and 4K Blu-ray discs but doesn’t render games at 4K, while the One X does. Both consoles can display HDR, provided the TV supports HDR and its enhanced HDMI mode is switched on. The original Xbox One doesn’t do 4K gaming at all.
Why Is Allow HDR10 Grayed Out?
The console hasn’t detected HDR on that input yet. Check three things: the TV’s enhanced-bandwidth option is on for that HDMI port, the console is plugged into a port rated for 4K HDR, and the TV genuinely supports HDR. Confirm the result in 4K TV details, where HDR10 appears with a green check once detected.
