Have you ever found yourself wishing for just one more screen without wanting to buy a whole new monitor? If you have a laptop sitting around, you might be in luck. It’s a common question: can you use that laptop display as a second screen for your desktop computer? The answer is a resounding yes, and it’s more straightforward than you might think.
Using Built-in Windows Features
If both your desktop PC and laptop run Windows 10 or 11, you have a free, built-in solution. It’s called Projecting to this PC. First, on your laptop, go to Settings > System > Projecting to this PC. Change the setting to Available everywhere or Available everywhere on secure networks. Now, on your desktop 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, making it perfect for extending your workspace without any cables.
Connecting with a Physical Cable
While wireless is convenient, a wired connection often provides a smoother, more responsive experience. The simplest way is if your laptop has an HDMI input port, but this is very rare. Most laptop HDMI ports are outputs only. For a reliable wired solution, you’ll likely need software. Applications like Space Desk or Spacedesk create a connection over your local network. You install the server software on your main PC and the viewer application on your laptop. Once configured, it treats your laptop screen as a seamless extension of your desktop.
Choosing the Right Method for You
Your best choice depends on your needs. The built-in Windows feature is fantastic for quick, casual use—perfect for keeping an eye on a chat window or your email. For tasks that require more precision, like dragging applications between screens frequently, a software solution like Space Desk can offer lower latency and a more stable connection, feeling almost like a physically connected monitor.
Using your laptop as a second monitor is a brilliant way to repurpose hardware you already own. It boosts your productivity without costing a thing. Give the wireless method a try first; you might find it’s all you need to create a more efficient and comfortable computing setup.
