Has anybody had experience with Multi Projector setups? I've been looking around and run across several options:

The only type of presenting I've done is with a single Panasonic PT-D6000US, we want to branchout and do a really wide screen show. It will not be for a live performance (it seems like that is a big feature with most of those applications).
There isn't a need for 3D mapping, the projectors will be mounted above the screen, so we'll need to correct for distortion. We'll have a curved screen, and will need some sort of triggering system, whether it is a motion sensor, sound or light sensor or just a button that can be pushed. So the question is, what is the most cost effective simple multi-projector setup.

Thanks in advance for any advice!

  • Could you elaborate on te triggering system? What does it trigger? Just the next slide or transition? Commented Jan 22, 2013 at 22:54
  • @Bart Arondson as far as the trigger, what we want is a way to start the presentation when someone enters the room. It might mean that the presentation starts when a door is opened, or someone passes a sensor.

  • Ah I see. Isn't it easier to just have someone press the button when someone enters the room without fiddling with sensors? Of course it would be nice if it would work, but I would consider it more as a bonus. Commented Jan 25, 2013 at 23:58
  • @Bart Arondson It's absolutely a bonus! I'd just wanted to through it out, because it would be very nice...

Depending on your needs, it might be as simple as using the drivers that come with your system. I know that certain NVidia cards can make multiple video outputs appear as one single screen to Windows. In a case like that, it would simply be a matter or properly aligning the projectors (if they can handle the key-stoning themselves) A lens might be able to handle correcting for the curve.

  • The screen is going to be curved, so we need a way do digitally manipulate the lens distortion.

  • @circleb I am suggesting you may get better results with an amorphic lens. It depends if you have a regular curve or not, but may yield better results than digital alterations. (Or at least cheaper)
