To access the “Project” menu, simply press the Windows key and the letter “P” simultaneously (Windows + P). This action opens a sidebar with several display options. The most relevant choices are “Duplicate,” “Extend,” and “Second screen only.”
Duplicate
“Duplicate” mirrors your primary display on the secondary laptop screen. This is useful for presentations or situations where you want both screens to show the same content.
Extend
“Extend” expands your desktop across both screens, allowing you to drag windows and applications from one screen to the other. This is the most common and productive option for multitasking.
Second screen only
“Second screen only” disables the primary display and shows everything on the secondary laptop. This is ideal if you want to focus solely on the second screen or if your primary laptop display is damaged.
If your second laptop is not being detected when you use laptop as second monitor, try restarting both devices. Also, ensure that the display drivers are up to date. Right-click on the Start button, select “Device Manager,” expand “Display adapters,” right-click on your graphics card, and choose “Update driver.”
The “Connect” feature enables a wireless display connection. On the laptop you want to use laptop as second monitor, go to “Settings,” then “System,” and then “Projecting to this PC.” Ensure that the settings are configured to allow projections from other devices. On your primary laptop, press Windows + K to open the “Connect” panel and select the secondary laptop from the list of available devices.
Troubleshooting connection problems often involves checking your WiFi connection and firewall settings. Make sure both laptops are on the same network and that your firewall is not blocking the connection. Disabling the firewall temporarily can help determine if it’s the cause of the issue.
While using Windows built-in features is convenient and free, it does have limitations. Wireless connections can experience latency issues, especially with older hardware or congested networks. Compatibility problems may arise if your laptops have different operating system versions or outdated drivers. Despite these potential drawbacks, this method is a good starting point to use laptop as second monitor if you’re looking for a quick and easy solution.
Exploring Third-Party Software to Use Laptop as Second Monitor
For a more reliable and feature-rich experience, consider using third-party software to use laptop as second monitor. Several excellent options are available, each with its own strengths and weaknesses.
Spacedesk is a popular choice, known for being free and supporting multiple platforms, including Windows, Android, and even web browsers. This makes it versatile if you have devices running different operating systems. Duet Display, on the other hand, is a paid option but is often praised for its stability and performance. It also offers touch input support, making it an excellent choice if you want to use laptop as second monitor with a touchscreen device like an iPad. Other alternatives include options like MaxiVista, though they might have specific requirements or limitations.
Let’s take a closer look at Spacedesk as an example. To get started, you’ll need to download and install the Spacedesk Driver on the laptop you want to use as the main computer (the one that needs the extra screen). Then, install the Spacedesk Viewer on the laptop you intend to use as the second monitor. Both are available on the Spacedesk website.
Once installed, open the Spacedesk Driver on the primary laptop. It will display the IP address of the laptop. On the secondary laptop, open the Spacedesk Viewer. It should automatically detect the primary laptop. If not, you can manually enter the IP address. Once connected, you can configure the resolution, refresh rate, and quality settings in the Spacedesk Driver settings on the primary laptop. Lowering the resolution can improve performance if you experience lag.
Common troubleshooting steps with Spacedesk include checking the network connection, ensuring both laptops are on the same WiFi network, and verifying that the Spacedesk service is running on the primary laptop.
