Have you ever found yourself wishing for just a little more screen space? Maybe you’re working on a complex project and need to spread out your windows, or perhaps your main laptop screen has called it quits unexpectedly. In these situations, you might look over at a spare laptop and wonder if you can use it as a second monitor. The good news is, you often can.
While you can’t just plug a cable from one laptop to another as you would with a dedicated monitor, there are several clever software-based methods to extend your digital workspace. It’s a fantastic way to boost your productivity without spending any extra money on new hardware.
Using Built-in Features in Windows
If both of your laptops are running Windows 10 or 11, you have a powerful tool already built-in. The Projection feature allows you to extend your display wirelessly. First, on the laptop you want to use as the second screen, go to Settings > System > Projecting to this PC. Set it to “Available everywhere” or “Always on” for the best results. Then, on your main laptop, press the Windows key + P and select “Connect to a wireless display.” Your secondary laptop should appear in the list. This method creates a seamless extended desktop experience.
Exploring Third-Party Software Solutions
For those with different operating systems or who need more features, third-party applications are a great alternative. Programs like Spacedesk and Parsec are popular choices. These applications work by installing a “server” component on the laptop that will act as the monitor and a “client” on your main machine. They often provide low latency and can even work over a network, giving you a lot of flexibility. Many offer free versions that are perfectly adequate for basic screen extension.
Getting the Best Performance
To ensure a smooth experience, a strong connection is key. For the best results, connect both laptops to the same Wi-Fi network. An even better setup is to use an Ethernet cable to connect both devices to your router, which minimizes lag. If you’re using a software solution, closing unnecessary applications on both machines can also free up resources and make the screen sharing more responsive.
Using another laptop as a monitor is a clever trick that can save the day. Whether you use the built-in Windows settings or a dedicated app, you can easily double your screen real estate and create a more efficient workflow. Give it a try and see how much more you can get done.
