Ensure your laptop is selected from the touch screen or push button controller, and adapter/cable connections are secure (HDMI or VGA).

• Press Windows Start Menu key + P (for Projector settings).  Or press FN + proper Function Key to change the video output.  The F7 or F8 key are most common (refer to pics further below for visuals).
  
  • Note: The proper function key is one of the F_ keys located above the number set; it is different depending on make and model of the laptop.
    
    

• After changing the video output, wait a few seconds for video signal to sync.
  
  
• The four video displayed outputs are:
  • PC screen only
  • Duplicate (this is the option you want to choose in most cases)!
  • Extend
  • Second screen only

If video quality is poor on the projector, change your video settings to alternate resolutions, until you find the one that works best for you.
