You’re looking at your sleek laptop and your brand-new gaming console or a second computer, and a question pops into your head: can I use this laptop as a monitor? It seems like a clever way to save space and money, using the screen you already have. The short answer is a bit more complicated than a simple yes or no, but with the right tools, it’s absolutely possible.
Why Using Your Laptop Screen Isn’t Straightforward
Most laptops are designed as all-in-one units. Their video ports, like HDMI or DisplayPort, are typically outputs, not inputs. This means they are built to send a signal out to a larger monitor or projector, not to receive one from another device. It’s a one-way street, which is the primary reason you can’t just plug a cable from your PC into your laptop and have it work.
Software Solutions to Bridge the Gap
Since a physical cable often won’t work, the most reliable method is to use software. These programs work over your local network, effectively letting you control one computer from another and using the laptop’s display as a window into the second machine.
For a seamless experience, applications like Windows Remote Desktop, Parsec, or Space Desk are excellent choices. They are particularly popular for gaming or low-latency tasks. For general use or accessing your work computer, built-in tools like Windows’ own Remote Desktop Connection or third-party apps like TeamViewer can get the job done.
When a Physical Connection Might Work
There is a small exception for some very specific, modern laptops. A handful of high-end models with USB-C ports that support Thunderbolt 3 or later may have a feature called “DisplayPort Alt Mode.” This can sometimes allow the port to function as an input. However, this is rare and not a standard feature, so it’s best not to rely on it unless your laptop’s manual explicitly states it supports video-in.
Choosing the Best Method for You
If your goal is to play console games on your laptop screen, software like Parsec is your best bet, provided your console and laptop are on the same network. For extending your work computer’s display to your laptop for productivity, Windows Remote Desktop is a solid, built-in option. The software route offers fantastic flexibility, even if it introduces a tiny amount of latency compared to a direct cable connection.
While you can’t usually connect a simple HDMI cable between devices, using your laptop as a secondary display is a very achievable goal. By leveraging smart software solutions, you can repurpose your laptop’s screen for a more versatile and efficient setup without spending any extra money on new hardware.
