You’re looking at your sleek laptop and your older desktop PC, 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 that beautiful laptop screen for another computer. The short answer is a bit more complicated than a simple yes or no, but we’re here to clear it all up for you.
While it might seem like you could just plug one device into the other, it doesn’t work that way with a standard cable. Laptop video ports, like HDMI or USB-C, are typically designed as outputs to send a signal to an external display. They are not usually inputs for receiving a signal from another computer. However, don’t worry—there are still several effective ways to achieve this.
Your Best Bet: Software Solutions
For most people, using software is the most practical and cost-effective method. These programs use your home network to share the screen between your two computers. You install a small application on both your laptop and the primary computer you want to view. The laptop then acts as a secondary display, allowing you to drag windows and use your mouse across both screens seamlessly. It’s a fantastic way to boost your productivity without any extra hardware.
When a Hardware Solution Works
There is one specific hardware scenario that works, but it’s quite rare. Some high-end gaming laptops feature a mini DisplayPort or a specific USB-C port that can function as a video input. You would need to check your laptop’s technical specifications thoroughly to see if it supports this “video-in” feature. For the vast majority of laptops, this is not an available option, which is why software is the recommended route.
Setting Up Screen Sharing on Your Network
Getting started with software is straightforward. First, ensure both your laptop and main computer are connected to the same Wi-Fi network. Then, choose a remote desktop application. For Windows users, the built-in “Projecting to this PC” feature is a great place to start. For Mac users, the built-in Sidecar feature works wonderfully between a Mac and an iPad, but for a laptop-to-laptop connection, third-party apps are your best friend. These programs create a secure bridge, making the process feel almost magical.
A Handy Way to Extend Your Workspace
So, while you can’t typically plug in a single cable, you absolutely can use your laptop as a monitor. By leveraging the power of your local network and some clever software, you can create a flexible, dual-screen setup that makes working from multiple devices a breeze. It’s a simple solution that can make a big difference in your daily workflow.
