I'll explain - it's a rather simple concept - you send a plain black field to the video input of the projector. Thus, projecting black.
Which, as you say is 'no light'. How do you describe projecting an image though? Should he have said, "project no light instead of projecting a varied mixture of primary colours that happen to construct an image?"
The pedants on this forum really do hack me off sometimes. Do they think it makes them look clever?

Someone is going to have to explain this to me... how could you "project" black? Surely black is the lack of light, so where there's black, nothing would be projected. That would explain why those parts would be transparent - because there's no light hitting the screen.
