How easy would it be to make a 12V Electric Screen trigger.
I assume its a relay of some sort.

Sorry mate, you're going to have to be more specific.
Do you want a 12V trigger for the screen - ie you've got a trigger output on your amp or a 12V trigger output that works in sync with your projector?
I can think of ways of doing both, but I'm not sure which you need :?~:-?~:???:

Sorry for l8 reply.
I have a projector with a 12v 13 milliamp output thats live when the PJ is on and no feed when off.
I want this to switch on/off a relay that will raise and lower my electric screen.

is the screen currently controlled by a switch with two positions, down and up? Do you have to hold one position to get it to move or does flicking it one way cause it to drop and then back again makes it go up (kindof like automatic car windows)?
How willing are you to perform minor surgery on the screen mechanism?
Replacing the latter type of switch is easy, replacing the former is hard :(

The screen has an automatic switch and remote control 120" Mustang.
I'd like to synchronize it with epson 720.
