HDR SDR Brightness Assistant is a Windows desktop utility for adjusting Windows SDR content brightness while HDR is enabled.

Quick Checks

If brightness changes do not appear to work:

  1. Make sure Windows HDR is enabled for the target display.
  2. Open Windows Settings > System > Display and confirm the display supports HDR.
  3. Open HDR SDR Brightness Assistant from the system tray.
  4. Adjust Day or Night SDR brightness and click Apply now.
  5. If the display still looks incorrect, run Microsoft's Windows HDR Calibration app.

Startup

The Microsoft Store version uses the Windows packaged-app startup task. Startup is disabled by default. To start the app with Windows, enable Start with Windows in the app or enable the app in Windows Settings > Apps > Startup.

If Windows reports that startup is disabled by system policy, the app respects that setting.

Store Version

The Microsoft Store version is a paid app with a time-limited free trial. It has no in-app purchases, donation prompts, subscriptions, supporter-code entry, advertising, or unlock codes.

Privacy

The app stores settings locally on the current Windows user profile. It does not require an account and does not collect or transmit telemetry or personal data.
