How to Enable & Tune HDR on Windows 11

Before enabling HDR, confirm your setup meets these requirements — if any one piece is missing, HDR will either be unavailable or produce incorrect colour output.

Go to Settings → System → Display. Click the monitor you want to enable HDR on (important on multi-monitor setups). Scroll to the HDR section and toggle Use HDR on.

If the HDR toggle is greyed out, your monitor, cable or GPU combination doesn't meet the requirements — check the requirements section above.

Windows HD Colour Settings

Click Windows HD Colour settings (appears when HDR is on) to access two important sliders:

SDR content brightness — controls how bright SDR content (the Windows desktop, non-HDR apps) looks when HDR mode is active. If your desktop looks dim with HDR on, increase this to 80–100.

HDR/SDR brightness balance — balances the brightness between HDR and SDR content displayed simultaneously. Tune this by eye.

Windows 11 includes an HDR Calibration app (download free from the Microsoft Store if not already installed). It walks you through setting peak brightness, minimum black level and tone mapping to match your specific panel's capabilities.

Run the calibration in a dimmed room for accurate results. The calibration creates an ICC profile that Windows uses to tonemap HDR content correctly for your monitor's actual peak brightness and colour gamut.

The most common HDR complaint on Windows is that the desktop and SDR apps look faded, grey or washed out when HDR is enabled. This is almost always a misconfiguration, not a hardware problem.

Fix 1: Increase SDR content brightness

In Settings → Display → Windows HD Colour settings, drag the SDR content brightness slider to the right (start around 70–80). This compensates for the monitor operating in a higher luminance mode.

Fix 2: Disable "Cinema" or "Movie" monitor preset

Many monitors automatically switch to a low-brightness film preset when they detect an HDR signal. Enter your monitor's OSD and switch the picture mode to HDR Game or HDR True Black — or simply disable any automatic preset switching.

Fix 3: Check GPU driver colour format

Open your GPU control panel (NVIDIA Control Panel / AMD Software) and confirm the output colour format is set to RGB Full Range or YCbCr 4:4:4 — not YCbCr 4:2:0, which compresses chroma data and causes colour banding. Display EX's profile system saves this setting alongside HDR state.

The biggest limitation of Windows HDR is that it's a global toggle — there's no way to save "HDR on for gaming, HDR off for photo editing" as a named preset you can switch instantly. Display EX solves this.

Creating an HDR-on profile

Enable HDR and calibrate it to your liking. Open Display EX → New Profile → name it HDR — Gaming (or similar). Display EX snapshots the current HDR state, brightness settings and colour profile.

Creating an SDR profile

Turn HDR off. Optionally recalibrate the SDR brightness. Save as a second profile named SDR — Design or Desktop Work. You can now switch between HDR and SDR modes in one click from the tray icon.

Game HDR and desktop HDR are very different experiences. Most HDR games include their own in-game calibration — use it rather than relying solely on Windows settings.

Recommended workflow

1. Create a Display EX profile with HDR on, refresh rate at your gaming target (e.g. 144 Hz), and VRR enabled.

2. Set this profile as the auto-trigger for your game executable.

3. Inside the game, run the HDR calibration if available — look for peak brightness and black level sliders. Set peak brightness to match your monitor's spec (e.g. 600 nits for a DisplayHDR 600 panel).

4. For games without HDR calibration, use AutoHDR if your GPU and monitor support it — it applies tone-mapping to SDR games automatically. Enable it in Settings → Display → Windows HD Colour settings → Auto HDR.

HDR toggle is greyed out

Your monitor doesn't report HDR capability to Windows via EDID, or your cable doesn't support the required bandwidth. Try a different cable (HDMI 2.0+ or DP 1.4), make sure GPU drivers are up to date, and check if your monitor requires HDR to be enabled in its OSD first.

HDR resets to off after sleep or reboot

This is a known Windows bug on some monitor/driver combinations. Enable Re-apply profile on wake in Display EX — it re-sends the display configuration including HDR state after every sleep/wake cycle and on startup.

HDR looks worse than SDR

Your monitor's peak brightness is probably too low for HDR to make a visible improvement (under 400 nits). DisplayHDR 400 panels show minimal benefit from HDR. Consider disabling HDR for desktop use and enabling it only for content specifically mastered for your panel's brightness level.
