How to convert VGA to RJ45

How to convert VGA to RJ45

I needed a super long VGA cable to reach from the LCD my computer, which were on opposite sides of the room. Initially I was going to move my computer to the projector but decided against it. I read a few articles involved with VGA conversion and decided to give it a shot.
I have been working to extend audio and video signals with a few different projects so far, first was the RCA cable to CAT5 conversion boxes. I always feel constrained by the cords I use for all my electronics. I came up with the idea after watching a move in my dorm room. Although I have a decently sized room, I don’t have a huge monitor, only a 17” LCD. Even with a little rearranging on my desk, it still impossible to get it close enough for my viewing pleasure. The cords are just not long enough. I figured if I patch the VGA across a CAT5 cable (since I have a lot of it), I can just unplug the monitor and plug it in where ever I want in my room. I’ll just have to deal with some long cords running across my room while I watch the movie, a minor inconvenience.


The conversion isn’t to hard if you can find the right materials. A good RJ45 (Ethernet conversion box) is essential. The only soldering you have to do is 8 connection pins to the VGA port (twice, of course).

1. Cut and prep wires – You will need 16 wires 22 gauge recommended, any bigger and it will be difficult to solder. USE DIFFERENT COLORS. I can’t stress that enough, it will make you’re life a lot easier when matching up which wire goes to which connection. Cut the wires roughly 4 inches in length, stripping one end of each by a few millimeters.

2. Prep the boxes – Take a look at inside of your RJ45 box. They are not all the same, but they are similar. Find a good spot to put the VGA port that won’t interfere with any screws, RJ45 connections, and will have enough space to fit 8 wires. Use a dremel or drill to cut a hole to fit the VGA port. Make sure size it right, you don’t want it to fall through. Dry fit the piece a few times before you are confident that it will work, looks clean, and won’t interfere with anything.
