That may sound weird, but it's actually off-the-shelf tech for a couple of decades now: https://en.wikipedia.org/wiki/Digital_Light_Processing It's already the most common projector technology, not something new they're developing just for this.

1.3 million mirrors is actually low-resolution by modern standards.
