Where does the HD signal select option come in?

Coma.

Its doesn't since your projector isn't capable of HD natively. Set the resolution to 1024 x 768 via DVI or VGA and let MC scale everything for you. In the setup section of MC select the display to be a 4:3 computer monitor and you should be fine.
