Toggle your computer's video output settings. Check your computer's manual for how to do this, but most laptops use a keyboard combination of Fn and one of the F keys. Normally, you can choose between displaying the computer on the projector only, on both the projector and computer, or the computer only. You can also find settings to control this by going to "Start," "Settings," "Control Panel," "Display" and the Settings tab.
