I recently purchased some 8x8 RGB LED Matrix panels and decided to test them out by combining four of them into a low resolution video display.
I'm driving the panels using an ESP32 microcontroller and the video is being sent via Bluetooth from a nearby computer, which scales it down to the appropriate size, encodes it into an RGB565 data stream, then sends it to the ESP32.
The web Bluetooth API is used to send the data from a browser, so it's not tied to a particular platform and can send data from many different types of device.
The ESP32 code can be found here...

The website for sending the video is here...
