Windows 10 – Duplicate or Extend Your Screen

If you’ve got a second screen connected to your Windows computer, either an interactive screen, projector or a screen by the side, Windows makes it easy to change your second screen or projector display mode. To switch between display modes simply press Windows + P.

– PC screen only uses your current display.

– Duplicate shows the same content on both displays (monitors/interactive screens/projectors).

– Extend splits the image between the two displays. This is useful for displaying your presentation on the interactive screen/projector while displaying your speaking notes on the PC/laptop.

– Show second screen only turns off the current display and displays the desktop only on the interactive screen/projector.

If you can’t see anything on the interactive screen/projector make sure the display mode is set to Duplicate Desktop.  The new setting should take effect straight away.

If all else fails, try unplugging the HDMI/VGA cable and plugging it back in again.
