A mismatch between the source, player output and display interpretation can make HDR appear washed out. Incorrect picture settings or an unsuitable conversion path can also contribute. First establish whether the programme is HDR and whether the display has entered an appropriate mode before increasing colour saturation.
Inspect the active mode
Check the television’s information panel and the player’s media details if available. Compare one known SDR sample and one known HDR sample using the same input. If both look flat, investigate the general signal path. If only HDR looks wrong, focus on HDR support, output conversion and the active HDR picture preset.
Change one link at a time
Temporarily bypass an optional HDMI switch or receiver if practical, then retest. Confirm that the selected port supports the required format and that any documented enhanced-input option is set appropriately. Do not change service credentials or reinstall the app when the same visible problem appears in unrelated local HDR material.
Avoid cosmetic overcorrection
Increasing saturation may make colours stronger without fixing the incorrect brightness mapping. Extreme contrast can hide the problem by clipping detail. Record the original settings, restore a sensible preset for comparison and describe whether blacks, faces or highlights look wrong when seeking help. A photograph alone may not capture an HDR display accurately.
