Which segment drops the feature?

Bandwidth fit does not establish HDR, variable refresh, content protection, audio, or DSC through an adapter or dock.

Source → adapter/dock → display

Every terminating component matters

A feature may work directly and disappear through an adapter because the converter, dock output, EDID path, or operating-system route does not expose it. Treat Unknown as a verification task, not a silent Yes.
