How to Add a Laptop as a Monitor With Miracast
Windows 10 systems come with a feature called Miracast that lets you project your present computer’s display to a different computer. The only requirement is that both computers are running a modern enough version of Windows 10 that includes Miracast. If you can use this option to use your laptop as a monitor, it’s the easiest method.
Project to Your Laptop Screen With a Third-Party App
If both computers aren’t running Windows 10, you can cast your screen to your laptop display using a third-party app instead. In this example, we’ll use Spacedesk to project to a secondary laptop screen. Spacedesk requires you to install the main program on the laptop you want to project your display from, and the Viewer program on the computer you want to project your display to. Other software that can help you accomplish this same thing include:
Synergy Input Director Ultramon
How to Use Chrome Remote Desktop
Another quick and simple solution to use a laptop as a monitor is to take advantage of Google’s free Chrome Remote Desktop service. This solution is ideal in a scenario where you want to mirror your screen to another monitor so that other people can see it. Chrome Remote Desktop will let you display your desktop on the laptop’s screen.
