The short answer

Section titled “The short answer”

HDR is not a software toggle that makes any display look better. It needs:

  • a display with real HDR capability (local dimming or OLED-level contrast);
  • a GPU/port/cable that carries the required bandwidth;
  • HDR content or a game with HDR support;
  • Windows HDR enabled and calibrated;
  • correct in-game HDR settings.

A “HDR400” edge-lit panel often looks worse in HDR than a good SDR calibration. Enable it deliberately, per display.

Windows setup

Section titled “Windows setup”
  1. Connect the display with the correct cable/port.
  2. Settings → System → Display → HDR; enable HDR if available.
  3. Run Windows HDR Calibration and follow the patterns.
  4. Set SDR content brightness to taste; do not max it.
  5. In games, enable HDR in-game and calibrate with the game’s own sliders.

What HDR changes

Section titled “What HDR changes”
Control What it does Common mistake
HDR on/off Switches the output transfer function Leaving HDR on for SDR desktop
SDR brightness Brightness of non-HDR content Maxing it and clipping highlights
Auto HDR Expands SDR games to HDR Expecting it to work in every game
Game HDR Per-game HDR calibration Using Windows calibration only
Peak brightness Display capability Trusting a “HDR1000” logo without testing

When to leave it off

Section titled “When to leave it off”
  • The panel has no local dimming and poor black levels.
  • The game’s HDR implementation is broken (washed-out image).
  • You do desktop work and do not want the SDR/HDR switching overhead.
  • The cable/port cannot carry the resolution + refresh + HDR combination.

Test properly

Section titled “Test properly”
  • Use a calibration pattern or a known HDR test clip.
  • Check black level, highlight detail and color banding.
  • Compare SDR and HDR in the same scene.
  • Verify the display OSD reports HDR mode.
  • Do not judge HDR from the Windows desktop alone.
