Ethernet to HDMI Converter

No, HDMI-ethernet adapters are for extending the length of the HDMI cable. It requires an adapter on each end to make it HDMI-ethernet-HDMI.

The HDMI port on your TV doesn't know how to "talk" to a network. Those adapters just pass the video signal along a different type of cable.


If you have a Roku, why do you want your TV to be online too? Many people intentionally prevent their TVs from reaching the internet.

Would an ethernet to HDMI converter allow me to plug my TV directly into my modem so I do not have to rely on my WiFi signal?

No, that's not how it works

Wanting to do this for a TV, without ethernet input, that I have set-up in my backyard. The TV is approx. 50 feet from my modem, 1 interior wall & 1 exterior wall between.

You are going to have to run an extender closer to the TV... or buy a TV with a physical plug

Also, if the ethernet is plugged into HDMI #1, and my Roku is in HDMI#2; would I still need the WiFi connection for my Roku to work, or can I use the ethernet connected to the TV for the signal?

You are extremely confused... let me start off with the simple truth - NOTHING is using HDMI 1.4 or 2.0... nothing, literally nothing, it was a pie in the sky idea that just never took off.

2) In order for "Ethernet over HDMI to work" you are still going to have to plug a device (most models had the TV being plugged up) to an Ethernet cord and then the Internet would be "shared" to the other HDMI devices plugged up to your TV - think about your 2nd question, you wouldn't need to connect your Roku to your internet, because the TV would share it's connection with the Roku. This still requires a physical cat 5e or 6 cord run to your TV (Edited to Add: This didn't happen, it in theory would have, but it didn't happen, there was no real world usage for it, so it NEVER happened)

3) ... Ethernet to HDMI, or HDMI to Ethernet isn't really a thing, it's still a physical connection that must exist if you are using the Ethernet over HDMI.

Your best bet is to extend your wifi or run a cat5e or cat6 cord out to your new TV... I would recommend running a cat5e or cat6 out to the area and then setting up an unmanaged switch close to your devices.

Thanks. I was definitely confused on the application. This helps simplify it for me.

Thanks for helping break it down for me, definitely helpful.

May look into this if it continues to be a problem

What about just running a hard wire from the modem through the ceiling into the ROKU? I ran a wire, had it come through the wall then plugged into an Ethernet splitter. Split it to Roku, Amazon Cube, and PS4.
