Has the HDMI port on the DH87RL Ethernet out?
Hello Tobias_Claren, thanks for joining the Intel Community.
I would like to inform you that the HDMI port on that motherboard does not come with Ethernet.
This kind of set up is more frequent when you are connecting you TV to a game console for example.
