    Only way I have on a budget is 3 proj, using 2x head2go, I’ve only done with 2 projectors with 1x head2go but I think it’s possible. The manual and online says you Can piggy back 2x head2go giving you 3x1024x768 with my setup. Do soft edge in mad mapper.... let me know how you go or thoughts?

    To do a soft-edge on 3 outputs, you need the
    - 3 video outputs: on a macPro you can connect 6 screens, or recent macBook Pro 3 full HD should be ok, if your computer can't handle 3 video connections, you can use a DualHead2Go or TripleHead2Go
    - setup in MadMapper: you have
    - create 3 projectors dispatched in the stage (MM virtual space)
    - assign each projector to the corresponding OS screen
    - place one quad on each projector and adjust them so they overlap enough (20-30% of the projector width/height). Use a white picture at the moment. You have to set mesh warping with bezier to get nice rectangle with vertical sides of the projectors parallel.
    - then use a soft-edge calibration image applied on each quad to adjust the UVs.

    You can find calibration images here: ...

    As an addition to this tutorial, I'd suggest to create a virtual output using Spout that will be used as a container. This container will be played in all the warped and edge-blended quads. So, you can place elements of any size anywhere in this big canvas, like logos or live camera feeds, and they will have the blending and warping applied even if they are not the same size as the background media.

    Startech sells a miniDP to 4 DP interface, using the DP 1.4 ability to create multidesktop configurations out of a 4K capable connector. Maximum resolution with this interface is 4 outputs at 1920x1080 @ 60fps.
