There’s no denying that giant video walls are awesome, but creating one usually means a fairly complex setup with either multiple computers or very expensive video cards. Now, with Pi Wall, you can make a video wall as large as your wallet will allow with only one Raspi per monitor, and a single master pi to control the whole shebang.
As long as you have a few displays with an HDMI input, it’s easy to turn them into a giant monitor. Just plug one Pi per monitor into a network switch, have a Pi (or other Linux box) transmit a video to all the video tiles, and sit back and enjoy the show.
Right now there is an installation guide for creating a Pi Wall, but there are a few limitations; this software only works with the video player provided with the Raspberry Pi, omxplayer. If you’re looking to create an enormous display for a flight simulator or what have you, you might need to do a bit of tinkering under the hood.
