Multiple video cards

I have a requirement to project a 36X10 ft display with a variety of images from a PC/MAC. I would like to use a second video card in the PC/MAC such as the MATROX M series that can provide the image blending for the 2 projectors. The primary video port on the PC/MAC would be the preview monitor and the BoinxTV software could handle the switching. Is this doable?

if it’s a hackintosh, Boinx doesn’t support those machines. I’m not sure what your meaning by image blending, BoinxTV has only 1 live output. If your system can use multiple screens at once (extended desktop), then the live feed can be set to run on one of those screens, so long as it supports the resolution (1920x1080p max)
