Every projector actor is working on his own, like every other actor does. This is good, as it keeps the enormous flexability Isadora offers.
There are different ways to change this behavior. But the most easy way and a good way to work in general is, to put the actors you want to have the same settings for, into a user actor. If you then copy and paste this user actor, every time you change something in one of those instances, it will be 'cloned' to all other instances, as long, as you click on 'save & uptade all' after closing it. This is happening in the same and as well in all other scenes.
Here you'll find a tutorial about user actors and the 'cloning'.
A different approach would be to have only one projector actor in a 'secondary scene' which is always active in the background (activate scene actor), and send the video outputs from each scene to it with the broadcast and listening actors instead of separated projector actors.
Here the tutorial about activating scenes in the background and the broadcast / listener actors.
