Have you ever wished you had just a little more screen space? Maybe you’re working on a spreadsheet and need your reference document open side-by-side, or you want to keep an eye on your email while watching a tutorial. What if you could use that laptop sitting on your shelf as a quick and easy second monitor? The good news is, you probably can, and it’s simpler than you might think.
Using Built-in Windows Features
If you’re using a Windows PC as your main machine and a Windows laptop as your second screen, the easiest method is built right in. It’s called Projecting to this PC. First, on your laptop (the one becoming the monitor), go to Settings > System > Projecting to this PC. Set it to Available everywhere or Always on. Now, on your main PC, press the Windows Key + P and select Connect to a wireless display. Your laptop should appear in the list. This method works over Wi-Fi, so no cables are required.
Connecting with a Mac and Sidecar
For those in the Apple ecosystem, the process is beautifully simple with a feature called Sidecar. If you have a Mac and an iPad (running iPadOS 13 or later) or a compatible Mac laptop, you can use it as a second display wirelessly or with a cable. Just click the AirPlay icon in your Mac’s menu bar and select your iPad or other Mac to connect. It seamlessly adds the device as an extended desktop, and you can even use Apple Pencil for input.
When to Consider Third-Party Software
Sometimes the built-in options might not work due to hardware limitations or if you’re mixing different operating systems. This is where third-party software shines. Applications like Spacedesk or Parsec are excellent alternatives. They often provide a more stable connection and extra features, like higher refresh rates for smoother motion. You’ll typically install a piece of the software on both your main computer and your laptop, and the program handles the connection between them.
Getting the Most from Your Extended Screen
Once connected, a few simple tips can improve your experience. Use the extended display mode to give yourself a truly larger workspace, rather than just duplicating your screen. You can drag windows and applications between the two screens freely. This is perfect for keeping your primary work front and center while moving your communication tools, music player, or research materials to the secondary laptop screen.
Expanding your digital workspace doesn’t have to be expensive or complicated. With a bit of setup, that extra laptop can become a powerful productivity booster, giving you the screen real estate you need to work more efficiently.
