How to transmit audio/video through a modded composite/ethernet cable from my computer to my television? Answered

So here's the scenario: I have a new Windows 7 laptop, but it doesn't have any composite or s-video type ports. It does have an ethernet port/card, so I figured there must be some way for me to use that to connect my laptop to the big screen television in the basement. I followed https://www.instructables.com/id/How-to-Run-Composite-Video-Through-an-Ethernet-Jac/ and I came up with a new cable like the one described in that ible- an ethernet jack at one end, and a composite jack at the other end. However, I do realize that ethernet and composite have different ways of communicating and that they have different voltages, etc. I just wanted to know if there was a sure-fire way to mod my cable (resistors at certain pins, etc.), without much expense, so that I don't fry my television and get kicked out of the house.

I know that I could just buy something like this for five bucks off of ebay but the DIYer can't let it go.

the problem you're having is not the device to send it over its the fact that the Rj45 port is not design to send video out it for a internet connection. my question do you have a VGA port or a usb port to get a external usb to vga adaptor i then get the correct connection for the tv
