DIY DisplayLink adapter using ffmpeg and a Raspberry Pi to add a HDMI port to a laptop (pierre-couy.dev)

TLDR : My brand new laptop did not support DisplayPort over USB-C. I had a Raspberry Pi lying around unused, with its RJ45 and Ethernet ports, and I felt that I should be able to use it to bridge the gap between my laptop and my 2nd external monitor. After a lot of trial and error, I managed to get to something that I can comfortably use daily. This is a tutorial to reproduce this project in the form of a detailed writeup

I made this project a few months ago, and got some good feedback when I shared it. I also made a Github repo with scripts and config files (there is a link in the blog post), but I did not get a lot of feedback on it.

Anyway, I'd love to read your thoughts about this project.

I'm also looking for lemmy communities related to DIY tech projects and Raspberry Pis, so feel free to recommend some communities :)

Thanks for the post, looks fun. I've never considered doing something like that, happy to know it's possible.

I remember back in 2014 when I got a laptop with a micro-hdmi port without realising what a dog shit connector it was. The port died within the first month of use (during which it was probably unplugged and plugged a total of 20 times at most) and then I kept trying various tools online until I found this display over IP project and later got a display link dock for my next laptop.
