For two weeks now, I've been having trouble with the on air display. I hook up my Mac (os x mavericks) to projector/monitor and when I hit "on air" the presentation displays on my laptop instead of the projector. And I can't get it to present on the projector/monitor. The master control/designer screen disappears when this happens as well. When I click on the "settings" panel and choose "identify monitor" the numbers 1 and 2 appear on the same screen. Need some help with this. I've fiddled with every combination, but the 1 and 2 always appear together. Please help!
