I have a theater room with a projector as my main display. I have recently bought an old Mimo UM-740 7" touchscreen. I have it working as a secondary display, problem is, the touch screen is moving the mouse on the main display.

Is there a way to have just the touchscreen have touch features and not act as a track pad for the main display??

Ideally, I will have a media player on the main screen, and be able to select videos/music to play from the 7" touchscreen.

Please help. Thanks.
