HDR Screenshots

Written by Michel Boudreau

High Dynamic Range (HDR) significantly enhances visual fidelity, but its detection often fails due to hardware limitations, cable bottlenecks, or OS-level configurations. If your display supports HDR but the option is disabled in the GameGlass Hub settings, use the following steps to diagnose the issue.

🛠️ Core Requirements Checklist

Before troubleshooting software, ensure your hardware chain supports HDR10:

  • Monitor: Must be HDR10-compatible or VESA DisplayHDR certified. Check your monitor's On-Screen Display (OSD) menu to ensure HDR is set to "On" or "Auto."

  • Cable: Use DisplayPort 1.4 or HDMI 2.0+ (HDMI 2.1 is recommended for 4K at high refresh rates). Avoid passive adapters, which often strip HDR metadata.

  • GPU: NVIDIA GTX 10-series, AMD RX 400-series, or Intel 11th Gen (and newer) are generally required for stable support.

🪟 Windows 10 & 11

Windows often defaults to SDR to save power or bandwidth.

  1. Enable the Toggle: Go to Settings > System > Display. Select the correct monitor and toggle Use HDR to On.

  2. Power Settings: On laptops, HDR is often disabled on battery. Go to HDR settings and ensure "Allow HDR games and apps on battery" is checked.

  3. Check Capability (DxDiag):

    • Press Win + R, type dxdiag, and hit Enter.

    • Click Save All Information and open the text file.

    • Look for AdvancedColorSupported. If it says "No," Windows does not see your monitor as HDR-capable via the current connection.

  4. Fix "Washed Out" Colors: Download the Windows HDR Calibration app from the Microsoft Store to create a custom color profile for your specific panel's peak brightness.

🍎 Mac

Mac support is robust on Apple Silicon but can be finicky with third-party displays.

  1. Toggle HDR: Go to System Settings > Displays. Select your external monitor and ensure High Dynamic Range is checked.

  2. Check the Port: On Intel Macs, HDR may be limited to 1080p over certain adapters. Always prefer a direct Thunderbolt to DisplayPort cable or the Apple USB-C Digital AV Multiport Adapter.

  3. Battery Optimization: Go to System Settings > Battery > Options. If "Optimize video streaming while on battery" is enabled, macOS will force SDR playback to save energy.

🐧 Linux

HDR on Linux is currently in an experimental but rapidly evolving state (as of 2026).

  1. Compositor Support: HDR currently requires a Wayland compositor. KDE Plasma (6.0+) and Gamescope offer the most mature support. X11 (X.org) does not support HDR.

  2. Kernel & Drivers: Ensure you are on a recent kernel (6.x+) and using the latest Mesa (24.x+) or NVIDIA proprietary drivers (550+).

  3. Enablement:

    • KDE: Check "Enable HDR" in Display Settings.

    • Gamescope: Launch games using the --hdr-enabled flag.

    • Proton: For Windows games, use Proton 8.0 or newer with the environment variable DXVK_HDR=1.
