Match the symptom before changing settings
| What you observe | Where to focus |
|---|---|
| Use HDR switch is missing | Check panel capability, port, cable and active resolution |
| Desktop looks washed out | Adjust SDR content brightness and monitor mode |
| HDR works in games but not video | Check app, codec, streaming and playback requirements |
| HDR turns off at high refresh rate | Check cable and port bandwidth limits |
Diagnose HDR capability and signal path with evidence first
Record the display model, connection type, HDR capability reported by Windows, and whether the issue is missing HDR, washed-out colors, black screen, or HDR failing only in one app.
Check HDR on the desktop, in Windows HDR settings, and in one known HDR-capable app or video. If only one app fails, keep the repair at that app or content path.
Complete these focused checks: verify the exact monitor model supports HDR on the selected input; use a cable and port rated for the required resolution and refresh rate; check Advanced display for HDR certification and active signal mode; test with one known HDR source before changing color profiles. Take screenshots or notes before changing firmware, encryption, recovery, driver or power settings. Those records provide a return path if the first repair does not help.
Update Windows, the GPU driver, and display firmware only from official sources. Some HDR problems are corrected by driver or monitor firmware updates rather than Windows settings.
Save the monitor's current picture mode and Windows color settings before changing calibration, refresh rate, or GPU output format.
Establish a supported HDR signal
Connect directly, select the monitor HDR mode, set native resolution and choose a supported refresh rate. Reduce refresh temporarily if the connection lacks bandwidth.
Change one HDR variable at a time: Windows HDR toggle, display HDR mode, refresh rate, color depth, or cable/port. Retest the same HDR content after each change.
1Verification checkpoint
- Open HDR settings for the target display.
- Confirm Windows reports HDR support.
- If support disappears, check cable/port and detection first.
Configure Windows HDR controls
Open Settings > System > Display > HDR for the selected screen. Enable HDR, adjust SDR content brightness and run Windows HDR Calibration when supported.
Before changing HDR, refresh rate, color depth, or output format, write down the current working SDR mode. After each change, test the same known HDR content.
2Verification checkpoint
- Play known HDR content.
- Confirm the display switches correctly without washed-out or black output.
- If only one app fails, keep diagnosis app-specific.
Fix app-specific HDR playback
Confirm the game or streaming app supports HDR, update it and test full-screen playback. Check required codecs, account tier and hardware acceleration without installing unofficial codec packs.
Before changing HDR, refresh rate, color depth, or output format, write down the current working SDR mode. After each change, test the same known HDR content.
3Verification checkpoint
- Restart and retest HDR.
- Confirm the setting survives reboot.
- Stop when HDR remains consistent.
Interpret the result before escalating
If HDR capability and signal path improves after one focused change, repeat the same test twice and restore unrelated diagnostic changes. A different result in another Windows account points toward profile settings or policy; a different result with one cable, charger, display or peripheral points toward that device path. Keep the repair at the narrowest proven layer.
If the display cannot negotiate its advertised HDR mode with a known-good cable and port across operating systems, investigate the monitor firmware, input mode, cable bandwidth, or GPU output instead of Windows apps.
If HDR becomes available but colors look wrong, stop treating it as a detection failure. Move to calibration, color format, display mode, or content-specific diagnosis.
Verify the fix and choose the safe escalation
Restart Windows with HDR enabled and replay the same HDR sample. Confirm the display enters HDR mode and SDR desktop content remains usable.
Restore the normal refresh rate, second display, dock, and display enhancements one at a time. Keep the configuration that preserves HDR without exceeding the connection's bandwidth.
If Windows still reports no HDR support after correct detection, supported drivers, and a verified HDR-capable signal path, use repair install only after ruling out display and GPU limitations. Hardware capability cannot be added by resetting Windows.

Frequently asked questions
Why is the HDR switch missing?
Windows may not detect HDR capability at the current port, cable, resolution, refresh rate or monitor input mode.
Why does SDR content look washed out in HDR?
SDR content is mapped into the HDR range; adjust the SDR content brightness balance and monitor settings.
Can HDR and maximum refresh rate conflict?
Yes. The cable, port or display may not have enough bandwidth for both at the chosen resolution.
