In the following question:

How do I attach two monitors in a dual head configuration?

Someone asks how to run two monitors on a Pi, and the answer was to chain 2 Pis together. That made me curious as to what the practical limitations were on chaining Pis together. Can I do this with 3, 4, etc... Pis? Is there a limit?

  • If you are refering to the approach discussed in the accepted answer over there it would IMO very helpful to describe this directly in your question (to understand without the cross-reference). Just a suggestion. – Ghanima Feb 20 '15 at 12:21

    Websites can go off line or be taken down and as such, to make this a helpful answer you should cite some of the information from the link you give. – NoviceRaspberryPiGeek Feb 20 '15 at 2:35
  • Second that. It is nice if these Q/As are all self-contained ona single page without requiring a lot of chasing the threads which could be fleshed out into an answer. – SDsolar Jan 1 '17 at 6:59
  • OK, I followed that link and it seems identical to the other answer. And does not address multiple monitors that I can see. – SDsolar Jan 1 '17 at 7:00

Based on this press release (http://www.southampton.ac.uk/~sjc/raspberrypi/), it would appear that you can chain at least 20 together into a Lego Supercomputer.

  • Wow. Thanks for posting that. That is really cool.. I suspect it is all managed with a single monitor or VNC connection. But upvote for coolness. – SDsolar Jan 1 '17 at 6:57
