How can I display only selected material on projector?

Question

Hello

I will be managing the audio/visual booth at my school from next year onwards.

There are 2 projectors in the hall that display the same image, as does the computer monitor in the audio/visual booth (at the back of the hall on the balcony). I don't know how it is all hooked up as I have not yet had a look.

I need to be able to display only selected material on the projectors, so when i 'alt-tab' between different slideshows, videos etc. I want that to be visible ONLY on the computer monitor in the booth - not on the projectors as well. How do I go about this?

eg. I display a slideshow on the projectors for all to see, and then switch to my video application to play the video after the slideshow. When I do this - i do not want the part where i switch between the slideshow and video application to be visible on the projectors.

Switching off both projectors in between is not possible because of delays, and they are out of the remote's reach (from the booth)

Answer 1

Integrate the video into your slideshow.

-OR-

Run the video on a laptop on a different projector input.  Switch the projector to the laptop when you need to show a video.

Or just deal with it.  I don't really see the problem.  If you only have two applications running (video and slideshow), then just quickly tap alt-tab to switch between windows.  

If you are worried about leaving slideshow mode in Powerpoint and showing the audience your powerpoint edit screen, check out Powerpoint Viewer (free from Microsoft):

All it does is run slides.  You can't go into edit mode as with Powerpoint.
