Multi-Projection with Matrox QID LP PCIe

Is it possible to use “Softedge” for four projectors with this grafic card “Matrox QID LP PCIe”
Or does Softedge require a computer for each projector?
Thank you for helping

yes it would be possible. softedge is all within the software side of things and can be used in a very custom manner. fundamentally , softedge just creates a transparent blend to black layer and has a gamma setting to help adjust the blend.
