HDMI cable compatible with Ethernet connection
I own a ThinkPad Thunderbolt with an HDMI dock. Usually I connect it to my phone via Ethernet, which works perfectly. One time I mistakenly connected my laptop through HDMI instead of the monitor, and... I still had an Ethernet link? That’s something I thought was rare, but I’m not sure what happened.
Interesting – I've only heard about HDMI over Ethernet, not the reverse. It seems the HEC feature, known as HDMI Ethernet Channel, was first introduced with HDMI 1.4 in 2009 and hasn't been widely adopted. HDMI With Ethernet: What Is It & How Does It Work? (thehometheaterdiy.com)
Checking the HDMI cable shows "3d high quality hdmi cable with ethernet passthrough" 3d??? It functions, delivering 1080p at 120Hz. Now I receive Ethernet, and I connect my laptop via HDMI to the dock, then link the dock to the monitor using DP.
Hmm... when I first saw it, I thought it was a bit weird but also really interesting.
The HDMI cable supports Ethernet, which isn't particularly surprising. What stands out is the appearance of your network adapters. Open the Start menu, type "ncpa.cpl," and press Enter. If a new network interface appears, that's the next step.
