Hello

I would like to connect my desktop upstairs to my beamer downstairs using the electrical wiring. Is this possible? My idea was as following:
Upstairs:
- convert the desktop hdmi cable to a utp
- plug the utp cable into a device leading data over electrical wiring of the house. Like the Dlan wifi from Devolo.
Downstairs:
- utp cable in the receiving electrical wiring device
- convert utp to hdmi
- plug in hdmi to beamer

Hope this makes sense. Is it possible? Maybe there is an other/easier solution?

Thanks for your thoughts!

Why would you want to do this?

i don't know a beamer is, but if you want to extend the internet, there is powerline adapters, but for what you said you want to try to do, it sounds way over complicated.

As far as I'm aware HDMI over electrical wiring is not possible.

- trying to extend hdmi really, not the internet. Without having a 20m long hdmi cable going through the house.Since the electrical wire is already throughout the whole house it would ve been great to use this.

Data over power line never is and never has been a good idea. The wires are designed to carry high voltage high current low frequency signals and not high speed low voltage low current signals.

As far as I know such an HDMI adapter does not exist at all. I would say it is best to run a cable. Although I think I have heard of wireless

You can pump ethernet through the house wiring only because of the specialized devices to do that.

Here is an example of that same sort of device for HDMI, from 2008:

That is the only device like that I found, and it had 'issues'. And was not cheap.

Not entirely true, ethernet over powerlines has come along way and sends data over power lines. I finally broke down and bought a system the other day since no matter what I do, cannot get a good wifi signal on the other side of the house. The one adapter is plugged into a powerbar with surge protector into an outlet with a GFCI and that outlet is only 2 wires, no ground, and the other adapter is across the house, another 2 wire plug, about 5 circuits over on the breaker and I get 30mb/s out of my 50mb/s internet download speeds, the full 10mb/s upload speed and 10ms ping. That's pretty damn good. And these were cheap adapters. I'm pretty sure without the GFCI, powerbar, and 3 wire wiring, it would be even better.


Sadly though, there is no HDMI device for it. OP, you also have to consider the HDMI copy protection crap. Just because it might work, half the content might not work properly if the bit is set.

Thanks all.

It is true, ethernet over power lines work good. Im using a system myself and has surprisingly low latency and minimal loss in download/upload speed.

Eventually I hoped to use my high end desktop as a central computer (cloud-like I guess) to have several screens/keyboards/mice attached to, spread over the house and without using long cables. But Ill guess it has to wait a few more years.

Have you checked it for EMI and RFI? Because it generates LOTS
High speed data should always be sent over shielded cables or twisted pair to keep what you want in and what you don't want out.

not sure what you mean by EMI, RFI and LOTS. shielded cable start from the desktop to powerline adapter and is then sent encrypted over the powerline network, unshielded. As far as you mean electromagnetical interference, didnt notice any malfunctions.
