Have you ever found yourself wishing for just one more screen? Maybe your desktop monitor stopped working, or you need to keep an eye on a secondary task while working on your main laptop. It’s a common situation, and you might have looked at your perfectly good laptop screen and wondered if it could serve as that extra display. The good news is that in many cases, it can!
Using your laptop as a secondary monitor is a clever way to extend your digital workspace without buying new hardware. While it’s not as simple as plugging in a regular monitor, several methods can get the job done. Let’s look at the most effective ways to make it happen.
Using Built-in Features on Windows
If both your main PC and your laptop run on Windows 10 or 11, you’re in luck. The built-in Project feature is your best friend. First, ensure both devices are connected to the same Wi-Fi network. On your laptop (the one you want to use as a monitor), go to Settings > System > Projecting to this PC. Adjust the settings to allow connection and require a PIN for security. Then, on your primary PC, press the Windows Key + P and select Connect to a wireless display. Your laptop should appear in the list. This method effectively extends your desktop wirelessly.
Exploring Third-Party Software Options
For those who need more features or are using different operating systems, third-party software is a fantastic solution. Applications like SpaceDesk or Parsec are popular choices. These programs typically involve installing a “server” application on your primary computer and a “viewer” or “client” on your laptop. Once connected over your network, your laptop screen becomes a seamless extension of your main desktop. Many of these tools offer low latency and good image quality, making them great for general work tasks.
Important Limitations to Keep in Mind
It’s helpful to know about a common misconception upfront. Most laptops are not designed to act as an external monitor through a direct HDMI or USB-C cable. The video ports on a laptop are typically outputs only, meaning they send a signal out, not receive one in. This is why the software-based methods mentioned above are the standard and most reliable approach for this task.
With a little setup, your laptop can easily become a valuable second screen. Whether you use the built-in Windows tools or a dedicated application, you can boost your productivity and make the most of the devices you already own. Give one of these methods a try and enjoy your new, expanded workspace.
