Using a laptop screen as a secondary display can help professionals complete their tasks without any hassle.

  4. Open the Miracast app on laptops and desktops; it will display the screen in a split screen.
  5. Share anything with the secondary display simply by dragging and dropping media files into their session.

Both desktop computer and laptop must have an HDMI signal cable port to connect them.

  1. Download a third-party app that works specifically for screen casting.
  2. Install it on both devices, on your PC with HDMI/DVI or VGA port (HDMI cables can only connect two monitors).

  4. Once detected, go to Settings > Picture Settings or Picture Start Menu and make sure mirror device has the HotSpot option enabled. Check the interfaces of both applications, then press the Start button.
  5. After that, the screen will be flipped to your device’s screen via an HDMI/DVI or VGA cable, depending on its capabilities.
