After configuration, any video source that can provide DVI will work. We also used a displayport -> DVI and HDMI -> DVI cable successfully with a Mac laptop, Windows PC, Beaglebone, etc. It should work with any video source that can output DVI/HDMI/Displayport as long as you have the proper converter cable. Each set we sell is pre-programmed and tested with our wall so you may not even need to configure it unless you have something custom you would like to build.
Each order comes only with a receiver card, transmitter card, and DVI cable. You’ll need a few more things to make it all work such as a 5V 1A power supply with 2.5mm jack, Ethernet cable (up to 100 ft), ATX power supply with 5V @ 10-30 Amp output, some 16×32 RGB panels from Adafruit, wires, etc.
We have a lovely writeup of how we built the Adafruit 2ft x 2ft wall which covers a lot of what is involved in building an LED video display.
Please note! Building an LED video wall is not a a beginner project! There’s a lot of wiring and power management. We don’t sell all the components required so you may need to spend some time getting all the parts you need. Building a wall can take a few weekends and requires care and patience. Here at Adafruit we love this kind of thing,and we have documented the process as best as possible but there’s not a lot of documention out there about these systems so even though we got our wall working nicely we do not offer any kind of consulting or assistance beyond our forum tech support. This is not a project for a mission-critical, outdoor, mobile or other LED display or for use beyond hobbyist hacking!
