You can also choose the option to enable or disable Mirror Displays in the Display Menu drop down.

Other settings may result in various displayed image issues (flickering, doesn't display on one device, etc..). The computer may letterbox (have black strips along each side) while a projector or other additional display is connected. If you want a higher resolution while connected to a projector or other additional display, start with 1024 x 768 and then increase the resolution for each device and test for stability. Try to keep the resolutions consistent between multiple devices.
