then HDMI must be the method you use.
HDMI will give the better quality picture.
That said, are you sure there is not a VGA connector on the projector?
If there is, then you could ditch the "additional monitor" and connect to the projector with a VGA cable.
What makes you say, "I can only connect to it via HDMI" ?

Help - I am a teacher at a new school and have no tech support.
I have Dell laptop connected to a docking station with an additional monitor. I need to connect to a projector that is mounted and I can only connect to it via HDMI - my desk is about 30 feet from outlet. What is the best way to get connected? VGA (via connector) or HDMI cable
