How to display an image on a TV through twisted pair?

Question

Cables and wires

I may have misunderstood the question, for which I apologize in advance.
The situation is this. There is a computer, it is connected to a router. A special software for visualizing 3D images is launched on the computer. That is a computer with its own monitor.
There is also a TV to which three wires are connected: Power, twisted pair and coaxial cable (standard, television antenna).
Perhaps I don’t know something, but the person who saw all this before me said that the image from the computer can be transferred to the TV.
Am I missing something obvious, or is it complicated here? Is it technically feasible using only what we have? Perhaps there is some software?

Answer 1

The panel model must be guessed by telepaths.
Look, 99% that the panel has HDMI and .DLNA

Answer 2

There are video signal extenders that work over a dedicated UTP cable (perhaps the person meant this).
It looks like this:
signal source -> box -> utp cable -> box -> monitor.
At the same time, interfaces for extending the mouse and keyboard can be integrated there.

Answer 3

Or raise a DLNA server on your computer, here is a very good solution https://www.homemediaserver.ru/index.htm. We set up (the manual is on the site) we launch. On the TV in the signal sources, select our media server and rejoice. Important: this solution will not make a second monitor out of the TV (you will not see the desktop), but you can play media content.
