ACEPC Display Switcher, Windows Key + P, Duplicate, Extend, etc. 
The computer only is the default option–and the name says it all. Duplicate clones your screen to a connected secondary display, monitor, or projector. Extend expands the desktop so you can make room for extra windows. Projector only turns off your laptop's LCD and turns the projector into your monitor.
It worked with my two monitors. Thanks for this useful video.
