    High Dynamic Range (HDR) makes your screen look better. Bright areas shine. Dark areas keep their details. Colours become more lifelike.

    You can set up HDR on both Windows and Linux. Many people have shared good results. However, some users run into problems. One person got HDR working on Linux after it already worked on Windows. They simply adjusted a few settings.

    This guide will help you enable HDR step by step. We use short sentences. We explain everything clearly. Links are provided for key terms and data sources.


    Key Takeaways

    • Check your display first – Look for labels like HDR10 or Dolby Vision. Without a compatible screen, HDR will not work.

    • Update your graphics drivers – Old drivers cause most HDR issues. Always install the latest drivers from AMD, NVIDIA, or Intel.

    • Use the Windows HDR Calibration app – This fixes colour and brightness. It is essential for a good HDR experience.

    • On Linux, use Wayland and KDE Plasma – Log into a Wayland session. KDE Plasma 6.0 or newer works best.

    • Cables matter – Use HDMI 2.0 or DisplayPort 1.4 (or newer). Old cables cannot carry HDR signals.

    • SDR content may look washed out – Adjust the “SDR content brightness” slider on Windows. On Linux, tweak your monitor’s OSD.

    • When in trouble, check official guides and forums – Many problems have already been solved by other users.


    Prerequisites for HDR

    Before you change any settings, make sure your hardware and software are ready.

    Hardware and Display Support

    • Your monitor or TV must support HDR.

    Look for HDR10 or Dolby Vision on the box or in the manual. Most modern 4K monitors and TVs include HDR.

    • Your graphics card (GPU) must be new enough.

    Here is a quick reference:

    GPU Brand

    Recommended Series

    AMD

    Radeon RX 5000 or newer

    NVIDIA

    GeForce 16 series or newer

    Intel

    Core 11th Gen or newer

    • On Linux:

      • AMDGPU and NVIDIA drivers work well.

      • Intel Gen 9 graphics have experimental HDR support (still improving).

    • Cables: Use HDMI 2.0 or DisplayPort 1.4 (or newer).

    Older cables may not carry enough data for HDR.

    Operating System and Driver Requirements

    OS

    Required Version

    Windows

    Windows 11 Version 22H2 or later

    Linux

    KDE Plasma 6.0 or later (Wayland session)

    • Always install the latest graphics drivers.

      • Windows: Download from AMD, NVIDIA, or Intel.

      • Linux: Use the official AMDGPU or NVIDIA drivers.

    Tip: If your hardware does not meet these requirements, HDR may not work at all.


    Configuring HDR on Windows

    Enable HDR in Display Settings

    1. Press the Start button and type “Settings”. Open it.

    2. Go to SystemDisplay.

    3. If you have multiple monitors, select the HDR‑capable one at the top.

    4. Turn on the Use HDR toggle.

    5. Expand the HDR or HDR video streaming section.

    6. Uncheck “Turn off HDR when my PC is running on battery” if you want HDR always on (laptops only).

    Adjust Monitor HDR Options (Important)

    After enabling HDR, you need to fine‑tune it. Otherwise, colours may look grey or too bright.

    This tool lets you set minimum luminance, maximum luminance, and colour saturation.

    • Lower the “SDR content brightness” slider – found in Settings > System > Display > HDR.

    A value between 20 and 40 usually works best. This reduces the washed‑out look of non‑HDR content.

    • Load an ICC profile – Use the Display Color Calibration tool (search for it in the Start menu). This improves colour accuracy.

    Troubleshooting Windows HDR Issues

    Problem

    Possible Solution

    HDR toggle is greyed out

    Update your graphics driver. Check your cable (HDMI 2.0 or DP 1.4 minimum).

    HDR turns off on battery

    Go to HDR settings and uncheck the battery option.

    SDR content looks too bright/dark

    Adjust the SDR content brightness slider (see above).

    External HDR monitor shows “Not supported” when duplicating the desktop

    Switch to “Extend” mode instead of “Duplicate”.

    HDR still not working after updates

    Run regedit, go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers, look for any HDR‑related key and set its value to 0. Restart your PC.

    Warning: Always update your graphics drivers before changing HDR settings. Outdated drivers are the number one cause of problems.


    Configuring HDR on Linux

    Linux HDR support has improved a lot, but it is still not as polished as on Windows. You need the right combination of software.

    Enable HDR in Wayland and KDE Plasma

    1. Log into a Wayland session.

    At the login screen, choose “Plasma (Wayland)”.

    1. After logging in, open a terminal and type:

    echo "$XDG_SESSION_TYPE"

    If it prints wayland, you are good.

    1. Open System SettingsDisplay & Monitor.

    If your hardware supports HDR, you will see switches for HDR and colour profiles. Turn them on.

    1. For NVIDIA users: You need driver version 555.58 or newer.

    Older drivers may work but are less reliable.

    Note: As of 2025, only some distributions have full HDR support (e.g., Ubuntu 25.04, Fedora Workstation 42). Others may still be catching up.

    HDR for Gaming (using Gamescope)

    Gamescope is a micro‑compositor made by Valve. It helps you enable HDR in games.

    • Make sure you have Proton 8 or newer (if you use Steam).

    • In Steam, go to a game’s PropertiesLaunch Options.

    • Enter the following command (replace width, height, and refresh rate with your monitor’s values):

    ENABLE_HDR_WSI=1 gamescope --fullscreen -w 1920 -h 1080 -r 144 --hdr-enabled --hdr-debug-force-output -- env ENABLE_GAMESCOPE_WSI=1 DXVK_HDR=1 DISABLE_HDR_WSI=1 %command%
    • Start the game. If HDR works, you will see richer colours and brighter highlights.

    Known issues:

    • Some users report VRR stuttering when HDR is on.

    • NVIDIA support is not perfect yet.

    • Not all games work – HDR on Linux is still experimental.

    HDR for Movies (using MPV)

    MPV is the best video player for HDR on Linux. Version 0.40 or newer supports HDR via DRM direct rendering or DMA‑BUF Wayland.

    • Install MPV from your distribution’s package manager.

    • Create a config file ~/.config/mpv/mpv.conf with these recommended settings:

    profile=gpu-hq
    vo=gpu-next
    hwdec=auto-copy
    target-colorspace-hint=yes
    target-peak=1500
    • Adjust target-peak to match your monitor’s peak brightness (e.g., 1000 for a DisplayHDR 1000 screen).

    MPV uses more CPU power, especially with 10‑bit video, but the picture quality is much better than VLC.

    Troubleshooting Linux HDR Issues

    Problem

    Possible Solution

    Flickering or freezing with two monitors

    Use only one HDR monitor at a time. This is a known bug.

    HDR option does not appear in System Settings

    Make sure you are on KDE Plasma 6.0+ and a Wayland session. Update your drivers.

    Gamescope gives VRR stuttering

    Try a different refresh rate or turn off VRR. Wait for driver updates.

    No HDR metadata passthrough

    This is a current limitation of many Wayland compositors. Expect improvements in 2025‑2026.

    Alert: HDR support on Linux is not as stable as on Windows. Some users switch back to Windows for HDR gaming. But if you are patient, it does work for many titles.


    Frequently Asked Questions (FAQ)

    1. How do I check if my monitor supports HDR?

    Look for HDR10 or Dolby Vision on the box or in the manual.

    On Windows, open Settings > System > Display. If you see an HDR toggle, your monitor supports it.

    2. Why does my screen look washed out after enabling HDR?

    HDR changes the colour and brightness range.

    • On Windows: Lower the SDR content brightness slider (to 20‑40).

    • On Linux: Adjust your monitor’s OSD (on‑screen display) settings.

    Also, run the Windows HDR Calibration app – it fixes most washed‑out issues.

    3. Can I use HDR on Linux with an NVIDIA graphics card?

    Yes, but you need driver version 555.58 or newer and a Wayland session (KDE Plasma 6.0+).

    Some games or apps may not work perfectly. Always keep your drivers and desktop updated.

    4. What should I do if HDR is not working on my second monitor?

    Try using only one HDR monitor at a time. Many systems struggle with two HDR displays.

    Update your graphics drivers and check your cables. If problems continue, use your main monitor for HDR tasks.


    Final Thoughts

    HDR makes your screen come alive. But you need the right hardware, updated drivers, and proper calibration.

    • Windows offers a polished, user‑friendly experience. Use the HDR Calibration app and adjust the SDR brightness slider.

    • Linux is catching up quickly. Use Wayland, KDE Plasma 6, Gamescope for gaming, and MPV for movies. Be prepared for some rough edges.

    Keep your system updated. Check official guides and forums when you run into problems. Once you have HDR working correctly, you will never want to go back to SDR.
