Multiple projectors/video mapping
(1/1)
Stephen Swaffer:
We have been using a TripleHeadtGo by Matrox for a couple of years-but we always fight making it work with newer Apple products-specifically a new Mac mini. It seems like there ae do drivers for the new iOS's-post Snow Leopard
What are people using for multiple displays? Has this become a Windows/PC world?

My church uses RenewedVision’s ProPresenter 7 with an external PCI-e chassis and a BlackMagic Design Decklink Duo card. We push 4 outputs (audience, stage, FOH, stream) as well as separate Alpha Key & Fill all from a newer Intel iMac.
Professionally, I am familiar with multi-destination switchers such as Analog Way’s Ascender.
A similar box to the Matrox would be the Datapath HX4 (HDMI) or FX4 (Displayport) or FX4-SDI.

Reviving this thread with a little more runway to find a solution before the first of December-I should have started in January I know.
Our specific application is edge blending multiple projectors to create one ultra wide screen. We just need a stable solution for use with QLab. The Matrox Triple Head lets us extend a desktop over up to 3 displays so up to a 5760x1080. The problem we are fighting is Matrox doesn't have any drivers to work with an OS newer than Catalina-at least that we have found.

Have you checked out pro video player from renewed vision? I’ve mapped video across 9 tvs of various size with it before and it has worked great. I haven’t used it with sdi output cards but that would be the first thing I’d investigate if I needed a solution today.

Depending on the projector, you can sometimes do this natively in the projector itself. It's not ideal, but the price is right in a pinch.
Most any media server should do this, like PVP that Erik mentioned, or Arkaos, or similar.
