on making a huge video wall with usb monitors - what are the gotchas

I would like to make a low cost video wall using USB based monitors, but in watching your youtube video about 14 videos on a single computer, it gave the caveat that some usb hosts run our of resources - so how can I avoid that - what type of computer, and what type of hub do I need to make this work?

Thanks for your interest! The video is a proof of concept to show what is possible, but even putting aside resource limitations, neither USB 2.0 nor 3.0 has enough bandwidth for smooth playback across a video wall.

For publicly-facing setups such as a video wall, purchasing specialized hardware or a purpose-built PC with multiple internal graphics cards is the best approach.

We wish you the best of luck with your project!
