Many of us rely on dual-display working environments to ease out the work and multitask efficiently. If you have a laptop that’s lying around and you are looking to extend or mirror your primary PC, you can use your laptop as a secondary display. The wireless arrangement makes up for an effective way of building a home setup without looking for a new secondary display and cables.
However, you have to use a desktop and laptop that run on the same operating system. If you’re running Windows both on your desktop and laptop, you have the flexibility to wirelessly extend and mirror the display.
There’s a catch here if the desktop isn’t connected to the same Wi-Fi as the laptop, the connection won’t take place. We have come across the same scenario while connecting a LAN-enabled Windows PC and a Wi-Fi-connected laptop. In this case, we used a third-party application for extending and mirroring the desktop screen onto the laptop screen seamlessly.
How to Use a Laptop as a Secondary Display to Extend and Mirror Desktop’s Screen Wirelessly on Windows

- On your Desktop, open Start and go to Settings > Apps & Features.

- After the installation, go to the Projecting to this PC page and make the changes as shown below.

- In the primary desktop, go to Miracast or use Windows ⊞ + K and select the laptop or secondary display in the list of detected devices.
How to Extend PC Screen on Secondary Laptop Wirelessly using SpaceDesk application on Windows
The process has gotten a bit tricky here, as the Windows PC that we use doesn’t have a Wi-Fi card and uses LAN for the internet. Whereas, the laptop connects to the Wi-Fi connection of the same LAN connection of the router.
In this case, the regular way of connecting the devices by using the Wireless display or Mircast didn’t work. This is because the PC cannot detect the wireless displays. We have used the SpaceDesk application that can use the IP address to use the laptop as a secondary display.
- Go to SpaceDesk’s official website and Download the installation file.
- Open the installation file and complete the setup on your primary Windows PC.
- On the laptop or the secondary display, go to the Windows Store and search for the SpaceDesk application.
- Install and launch the application to detect the primary display or Windows PC.
- Here, you can see the detected Windows PC on your laptop with the IP address mentioned below the name of the PC.
- Click on the PC shown on the SpaceDesk application that you need to extend and mirror on your laptop screen.
- Lastly, use Windows ⊞ + P to change between extending or mirroring your Windows PC screen on the laptop as a secondary display.
