I purchased a video adapter for my imac. I plugged it in and my screen went from 17' wide screen to 640-480 standard. How can I keep my widescreen resolution while have this plugged in?
Check the Display preferences in the control panels. If it allows driving 2 displays you'll see the them both listed. I think though that the iMac only mirrors a dispaly which means that it will be the same size and image on both displays. If that's the case get a low priced DV camera and connect it to the firewire. FCP can output to it. Connect amera analog out to you TV or real video monitor.
