3-projector set up that needs to alternate between single image and treating each projection area individually

@juriaan This is remarkably helpful. I am now looking up how to get started with Izzy map.  Someone mentioned that it is not available with the demo version. Is this true?  Thank you for your answer!

@michel Thank you Michel!  This is very helpful and I will get started with it right away!

It should not be a problem using the mapper in the demo version, but remember you cannot save your patch.

@michel Ok, thanks--that's good to know!  I have one more question: I was looking up the Matrox Triplehead2go and noticing that it costs over 200 dollars.  Would you happen to know of an alternative that can be used to connect 3 hdmi projectors to a MacBook Pro 15" that will still be compatible with Isadora?

Thanks!

@gomer_pyle

Do you have a mac book pro with 2 thunderbolt and one HDMI connection? If yes you already have the possibility to connect 3 projectors. You just need 2 thunderbolt HDMI adapters.

@michel,

To my knowledge and experience, you cannot have 4 different screen with macOS, if you plug 2 miniDP, 1 hdmi plus the MBP screen, you need to have 1 seen copying another one.

If you want 3 different screen, the only solution is Matrox or datpath.

It is no problem with the MacBook Pro to have 3 external screens plus you laptop screen. I did this many times already in total you can have 5 screens if you have enough outputs.

@michel I have 4 thunderbolts but no HDMI.  I only have one thunderbolt to HDMI adapter, so 2 more would cost quite a bit as well--but still cheaper than the triple head, so might go that route instead. 

Thanks for the advice!

The new macbook pro, with thunderbolt 3, you can have up to 4 4k external screens or 2 5k. It will be much easier and flexible than a matrox.

@zedociel Thanks! I will not use Matrox since I do have the new MacBook Pro w/ thunderbolt 3
