That's very cool and impressive. I wanted to upvote your post twice, but Reddit doesn't allow that yet. The software side of your project must be equally impressive as, I guess, you had to write an entire driver for the panel to work as a screen ?
I don't know do you mean the screen sharing or just the driver to physically drive the panels? - For screen share section I just capture image from existing monitor, downscale it and send it to display like I send video frames to it. As for driving the LED panels I used this amazing library https://github.com/hzeller/rpi-rgb-led-matrix/
So basically I made Raspberry Pi Driven large LED matrix.
Year ago I bought my first RGB LED panel. Back when there was only one, ESP8266 was enough to drive it. It worked as a simple clock with date and temperature, I could not fit more on 64x32 (fun fact: back then I wrote all these scripts to play videos / visualize music etc., in this video I still use them, just slightly modified). Over time I started to really like it, so I ordered more panels, first expanding to 2x2 (had to switch from ESP8266 to ESP32) and now to 3x3 (and also had to switch, now to Raspberry Pi) Currently I am in the process of porting stuff from ESP32, as seen in the video, Python scripts used to interact with the display already work, but I need to work on the smart clock part. Oh, I also really like the test pattern (it's left over from testing) when it's doing nothing. The clock on that test pattern is just local time, not uptime or anything. Also, yes, I know it looks pretty cursed with cardboard on the back - it's temporary until I manage to 3D print the joints!!
Also about open sourcing it: I don't know yet - my code isn't finished and it's pretty much customized for my setup.
I don't know what else to say right now, so I guess just ask me in the comments.
Matrix panels are so expensive!! Did you just eat the cost or did you find a cheap one?

What are the are the hardware specs of the leds? Where can I buy one of those panels? Do they have name?
Very nice. I started with a 32x32 P5, then two to get a 64x32 P5 sign, then a single 64x32 P3, then two to get a 128x32 P3 sign, and am now running two units each with a 128x64 P2 panel. I drive them with a Pi 3 and the Adafruit RGB Matrix hat (HUB75), with a bunch of shell scripting and python to call the rpi-rgb-led-matrix drivers.
I use them for informational and eye-catch signs for local maker space events and volunteer organizations I work with. I've only done fixed images, scrolling, and color rotation so far; I'm interested in hearing more about how you do video and screen sharing.
This is one of the most pimp projects I've seen on here. EXCELSIOR man!

That is pretty cool project. Congrats
Nicely done! Love all the different integrations you set up.
I did a similar, but smaller project and it's used as a weather station/home automation smart display.
Please post a HOW-TO video...
