Expanding video preview to two projectors

I am trying to expand the video preview on After Effects to two separate projectors. I have a Mac with an M2 chip, and I got a Wavlink in order to expand my screen to two separate outputs, and it works, but when I go to After Effects to view the video preview, it mirrors the output instead of expanding. I’ve enabled Mercury Transmit and checked both projectors, but it’s just mirroring the output twice. Is it possible to expand the output so it can be staged through both projector screens?

    Apple makes this much harder than it should be. I haven’t found a solution and will follow this thread to see if someone else has an answer.
