I have a viewsonic 7827HD projector. I want it to automatically drive my Elite 100H Screen. I do not see a Trigger OUT port in back of projector. Can this projector drive my screen (Up/Down) and if so how do I set it up?

You could get something like the Niles CS12V...

But, I would just get a good universal remote control and use it to control the screen as long as your screen has infrared control of it.

You may also have an A/V receiver which has 12v outputs.

Or, you may have a cable box which has a switched output on the back you can plug a 12v power supply into.

There are many ways to do this if you want it to be automatic.
