Delock has not let me and not here. Even if you can find something to information anywhere, you can by this DP-2-HDMI adapter next to the image and sound locks (technically but that depends on the graphics card, here a NVS3100 with DP ++ - port on the notebook). Rein of the specification ago should each DP-2-HDMI adapter can, but now and then it still does not provide that.
