We are using Pro Presenter on a Mac mini, OS 10.14.6. The OBS shows up in the Displays System Prefs as USB Capture. We can send a Desktop image to the Preview screen, but we need to send a mirror image of our projector output. We've tried to mirror the images by holding the Control key and dragging the two screen icon in Displays to drag and drop. Apple support says this will work if the resolution is the same. The resolution of our projector shows as 1280 X 960, but the USB Capture choices are either 1600 X 900, 1080p, 1080i, or 720p. Suggestions?
