the cable does exactly what it should. Audio and video signals from the clean output DisplayPort to HDMI. Since there is nothing to flags.
Use the cable between a HP ProBook 6550b with DisplayPort and a Sony TV. Bildr sharp, sound is also transmitted.
Cable quality is ok, DisplayPort has a (standard) -lock. Protective caps for both plug ends too.
! Length 3m, as indicated in the title (in the description, however, a 5m cable is specified).
All good,
Ciao Matz
