We have built an IP based video wall (1 x 6 & 1 x 2 configurations) using raspberry pi's (not pi-wall as pi-walls suffer from memory crashes after 4 hours operation).
We've hit stumbling blocks and need someone to design a more robust solution.
Please see the configuration we're using at the moment, but we're open to alternative ideas.
If you're not technically capable of completing this project, please do not bid on it!!!
