Have the cable between a Samsung 3D home theater system and a Samsung SmartTV (46 ", also 3D) in use. There are no problems with image or sound no matter what medium (incl. BluRay 3D). The Samsung Anynet connection of two devices working properly.
And - here may be important for many - including the Audio Return Channel (ARC) works fine. That is the sound of the TV program is played back on the 5.1 amplifier of the BluRay player and not through the speakers built into the TV. However, only one of the HDMI sockets of the TV is suited to the other two HDMI connections does not work. This connector is also marked with ARC.
One more thing: It is a cable with Ethernet and I would have expected that the BluRay player's Internet connection (LAN) via HDMI tells the TV, or vice versa. That did not happen. Apparently the lies less on the cable, but the fact that the devices do not support that. This property, the cable is thus more theoretical nature and I can not report on it.
