Please forgive a newbie question, but what wiring would go in these conduits and for what purpose?

I'm surprised that the projector's manual didn't cover this. I'd for sure run HDMI, if it has a connection for it, and probably component video, in case the HDMI gets wonky (as it is sometimes prone to do).

BTW, don't know what "protected AC" is, but typically local codes prohibit running high voltage (AC) and and low voltage (everything else) in the same conduit...
