I bought Monoprice's Mini DisplayPort to DVI adapter with a plan to connect my Rev C 1.83 MBA to my 1080p Sanyo PLZ-2000 projector with a DVI to HDMI cable from the MDP adapter. However, while the MBA sees the projector in the Displays pane, nothing appears on the projector. If I connect with my Apple VGA adapter to the VGA input of the projector it works just fine. Any ideas on how to resolve this? TIA.
