High-dynamic range (HDR) is supported by Wayland's Color management and HDR protocol, and some compositors have implemented it. X.org has no plans to support HDR.

Requirements

HDR-capable display

• While many displays advertise HDR support, many may provide a suboptimal experience if they lack any form of local dimming. More information is available at RTINGS: Local Dimming on TVs.

HDR-capable GPU and driver

• AMDGPU and NVIDIA are both supported

Intel graphics has experimental HDR support with Gen 9 and newer

• The implementation is reportedly incomplete.

• Supported compositor

• Supported application

• Vulkan WSI with HDR support

Vulkan HDR WSI

VK_EXT_swapchain_colorspace and VK_EXT_hdr_metadata extensions are required for HDR support when using the Vulkan API.

• mesa 25.1 and later includes these extensions by default.

nvidia-open 595.58.03 and later also includes these extensions by default.

• NVIDIA users on drivers before 595.58.03 must install vk-hdr-layer-kwin6-git and set ENABLE_HDR_WSI1 in each game or application that will be used with HDR. Enabling this globally is not recommended.

Compositor configuration

KDE Plasma

See KDE#HDR.

Hyprland

Hyprland >= 0.55 will automatically switch to HDR mode in its default configuration, when the monitor and fullscreen content support it. To use HDR on the desktop you must set cm "hdr" and bitdepth 10 in your monitor configuration like so:

hl.monitor({
    -- ...
    bitdepth  10,
    cm  "hdr",
})

Additional settings can be found on the Hyprland wiki: monitor color management, render variables.

GNOME

Ensure mutter is >= 48.0.

Enable HDR in GNOME's display settings. The HDR toggle is per-monitor and is located next to the resolution and refresh rate setting.

Gamescope with Steam session

Valve's Steam compositor gamescope offers experimental HDR support. Following these steps will allow you to try out Valve's Steam client running through the HDR capable gamescope.

• Install gamescope and gamescope-session-steam-git

• You may create the optional config file ~/.config/environment.d/gamescope-session.conf with the following content:

  
  if [ "$XDG_SESSION_DESKTOP" = "gamescope" ] ; then
      SCREEN_WIDTH=1920
      SCREEN_HEIGHT=1080
      CONNECTOR=*,eDP-1
      CLIENTCMD="steam -gamepadui -pipewire-dmabuf"
      GAMESCOPECMD="/usr/bin/gamescope --hdr-enabled --hdr-itm-enable \
      --hide-cursor-delay 3000 --fade-out-duration 200 --xwayland-count 2 \
      -W $SCREEN_WIDTH -H $SCREEN_HEIGHT -O $CONNECTOR"
  fi
  

• Update the resolution values above to the correct ones. You can list your displays by running xrandr --query.

• You may need to set the Display CONNECTOR if it does not pick the right one by default.

You can now start gamescope from your login manager or a terminal using one of the following steps:

Via a login manager

Log out and select the Steam Big Picture in your login manager and log in.

Via the command line

1. Go to a new TTY by pressing Ctrl+Alt+F2

Log in and run gamescope-session-plus steam to start the standalone steam session in HDR.

• If networking does not work you can fix it by installing and enabling NetworkManager.

Configure Steam

1. In the general settings, under Display, you should now see HDR settings. Enable HDR and Experimental HDR Support.

2. Select an HDR compatible game and click on the cog next to it.

3. Set Compatibility to Force Proton 8.0 or Proton Experimental.

4. Set Game Resolution to match your monitor otherwise it will launch at Steam Deck native resolution.

5. Click Play to start the game. Check the in-game settings to see if the HDR setting is available and enable it.

6. To switch back to your normal session, select Power and Switch to desktop mode from the Steam menu.

COSMIC

The COSMIC developers have promised HDR support in the initial stable release.

sway

Add render_bit_depth 10 and hdr off to the outputs's config in your sway config file, and start sway with WLR_RENDERERvulkan environment variable set.

Setup a binding to toggle hdr or toggle manually i.e.: swaymsg output DP-1 hdr toggle.

Application configuration

Wine/Proton

HDR through Wine or Steam Proton requires DXVK (2.1+) or VKD3D-Proton (2.8+), depending on DirectX version used by the game.

Without Gamescope

To use HDR without gamescope run a build of Wine which includes the Wayland driver.

• proton-ge-custom: install proton-ge-custom-bin and set PROTON_ENABLE_WAYLAND1 and PROTON_ENABLE_HDR1 https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/GE-Proton10-1.

• wine-tkg: install wine-tkg, set DXVK_HDR1, and unset DISPLAY.

• proton-cachyos or wine-cachyos: install your choice of proton-cachyos-native, wine-cachyos-opt, or wine-cachyos and set PROTON_ENABLE_WAYLAND1 and DXVK_HDR1 https://www.reddit.com/r/linux_gaming/comments/1km81f4/proton_cachy_10_released_native_wayland_gaming/.

With Gamescope

Gamescope with proper HDR requires scRGB and xx-color-management-v4 protocol support or frog-color-management-v1 protocol support in your compositor.

Because of this gamescope will not work with the vk-hdr-layer-kwin6-git layer. Ensure ENABLE_HDR_WSI is not 1.

You have many options for using gamescope depending on your desired configuration:

• Launch Steam with HDR enabled. All games will then have HDR enabled, but Steam and all games will be launched inside a gamescope window.

$ gamescope --hdr-enabled --steam -- env DXVK_HDR=1 steam

• Enable HDR for a single game in Steam. Set the following Launch options:

DXVK_HDR=1 gamescope -f --hdr-enabled -- %command%

• To launch a non-Steam game within gamescope:

$ DXVK_HDR=1 gamescope -f --hdr-enabled -- executable

RetroArch

HDR in RetroArch is supported from version 1.10.0 with Vulkan video driver. First, select video driver Vulkan. Then, enable HDR in RetroArch video settings via Settings tab > Video > HDR > Enable HDR.

$ retroarch

Native SDL

To run native games that use SDL with HDR set SDL_VIDEODRIVERwayland.

For example for Quake II RTX:

$ SDL_VIDEODRIVER=wayland quake2rtx

mpv

For best image quality mpv maintainers recommend using the gpu-next https://github.com/mpv-player/mpv/discussions/16105#discussioncomment-12629196 video output driver, which is the default. gpu-next supports HDR with --gpu-contextwaylandvk, which is selected by default on Wayland.

$ mpv "path/to/video"

Other ways of enabling Wayland HDR support include using the dmabuf-wayland video output and the drm GPU context.

$ mpv --vo=dmabuf-wayland "path/to/video"

• From the tty terminal, one could do (--gpu-contextdrm is selected by default)

$ mpv "path/to/video"

Firefox

firefox introduces working experimental HDR in 138.0 under the hidden preference gfx.color_management.hdr. You can enable it at about:config.

Stable HDR is still in progress https://bugzilla.mozilla.org/show_bug.cgi?id=hdr https://bugzilla.mozilla.org/show_bug.cgi?id=1642854.

Chromium

chromium has work-in-progress HDR support https://chromium-review.googlesource.com/c/chromium/src/+/6771393. Support has been merged as of version 141.0.7370.0.

Troubleshooting

HDR video samples

Kodi wiki maintains the list of fair use HDR video samples. These can be used to test the HDR output using video players that support HDR such as #mpv.

Broken screen sharing with HDR10

Pipewire attempts to stream what it sees as BGRA, which WebRTC cannot interpret, due to its current lack of capacity to interpret it. As such, a "ParamId:EnumFormat: 0:0 Invalid argument" exception is thrown and the WebRTC socket crashes for that application https://github.com/hyprwm/xdg-desktop-portal-hyprland/issues/52.

HDR option missing in games when using multiple AMD GPUs

Using multiple AMD GPUs can cause some games (e.g. RDR2) to hide the option to enable HDR in their graphics settings. This issue can be resolved by setting the DRI_PRIME environment variable to the desired card and excluding others (by appending a !) as explained in PRIME#For open source drivers—PRIME:

DRI_PRIME=pci-0000_2d_00_0!
