Using a laptop as a second monitor is a nifty way of expanding a display in a pinch, and it doesn’t require any cabling or ports. Some users may also find it cheaper and more convenient to use their outdated laptop as a display instead of spending cash on a new monitor. The only requirement for using a laptop as a monitor is that both devices must be on Windows 10.

  • On your laptop, click on the Windows icon.
  • Navigate to Settings, then System, and click on Projecting to this PC.
    • A window will open with the settings. There will be a text saying Add the Wireless Display optional feature to project to this PC with highlighted text below saying Optional features.
