By default, the auto-calibration built into MimioStudio will use the screen that is set as the main display. Also by default, the PC is the main display and the projector is the secondary display if you’re using an extended desktop.

If you want to calibrate the extended display, you will need to set the projector as the main display and the PC as the secondary display. You can do this by right-clicking on your desktop and selecting “Screen Resolution.”

Once you’ve made this adjustment, unplug the USB cable going from the projector to the computer and plug it back in. It should auto-calibrate the projected image.

After the calibration, switch it back so the PC is the main display and the projected image is the secondary display. You should still be able to use touch on the extended display.
