Using a multiple monitor setup can be very beneficial for certain tasks. If you do not have a second monitor, you may be able to use your laptop screen as a secondary display. To use your laptop as a monitor, both the main PC and laptop need to support Miracast connectivity. Please note that not all notebook computers support Miracast, so these instructions may not work for all models.
This article will show you how to use a laptop as a second monitor in Windows 10 and 11. Before we begin, you will need to ensure that both your devices are turned on, discoverable, and updated with the latest version of Windows.
How to use your laptop as a second monitor
To start, you need to enable your laptop for screen projection. You can do this by:
- Go to Settings on the laptop you want to use as a second display.
- Select System.
- Scroll down and select Projecting to this PC.
- Underneath the text “Some Windows and Android devices can project to this PC when you say it is OK” select the first drop-down menu and select Available everywhere on secure networks.
Once you finish enabling your laptop, switch over to your main PC:
- Use the Windows Key + P to open the display projection settings.
- Select Extend; This option allows you to use your laptop as a second monitor.
- Select Connect to a wireless display
- Select your laptop when its name appears to connect to it.
Now that your PC is projecting to your laptop, you can start using your laptop as a second monitor.
