We upgraded our laptop which does not have a VGA port. In our old setup, the laptop had a VGA output to the projector and then a usb converter plugged in to the laptop which connected via RCA to a DVD player with a coaxial out to the three tvs. Now that we are changing the laptop, but not the projector (which doesn't have HDMI), what do I need to keep the signal going to the tvs HDMI, but with an adapter close to the projector instead of the laptop? Does this make any sense?
