@woland Thanks for the Suggestion. Still - having this feature inside Stage Settings would enable the User to Safe the Setting with the Show. That would simplify Setup and reduce room for error, espacially in enviroments where we run multiple Shows from the same Computer. Cheers

Setting up the Beamers in System Preferences (outside of Isadora) in Portrait Mode (90 degree rotation) should be the only thing you need to do. 

Then they show up in Stage Setup vertically and the edge blending should work fine.

As always though, bench test your setup (or something as close to it as you can get) before arriving at the venue.
