Hdr too dark windows

Dark HDR may come from content mapping, output mode, or display settings.

Run the check

  1. Compare SDR and genuine HDR content from the same source.

  2. Record the Windows HDR setting and the monitor's HDR status.

  3. Change only one brightness or tone-mapping control, then repeat.

Read the result

Only SDR material appearing dark in HDR mode differs from a panel brightness fault.

Limits and next step

Browser test colors do not establish peak luminance or HDR certification.

Repeat the check after changing one setting or connection. Keep a record of what changed before deciding whether the device needs service.
