You’re looking at your sleek laptop and your brand-new gaming console, or perhaps a second computer, and a question pops into your head: can I use this laptop as a second monitor? It seems like a clever way to save space and get more use out of your devices. The short answer is a bit more complicated than a simple yes or no.
While your laptop’s screen is a perfectly good display, it isn’t designed to accept video input from another device in the same way a standard monitor does. Its video port is an output for sending a signal elsewhere. However, with the help of software and sometimes specific cables, you can absolutely repurpose that screen for other devices.
Using Software for a Wireless Connection
The most common and flexible method involves using software. Programs like Windows’ built-in Projecting to this PC feature allow another Windows computer to extend or duplicate its display to your laptop over Wi-Fi. You simply enable the setting on your laptop, and then from your main PC, select “Connect to a wireless display.” Third-party applications like Spacedesk or Parsec also achieve this, often with added features for gaming or creative work, creating a seamless second screen experience without any cables.
Connecting with Cables: A Hardware Approach
If you prefer a wired connection, the possibility depends heavily on your laptop’s hardware. Some gaming laptops feature an HDMI-in port, which lets you use them as a monitor directly. This is rare, though. For most people, a standard HDMI cable won’t work because the port is output-only. Specialized capture cards are another hardware option, where the card acts as a go-between, taking the video signal from your source and displaying it in software on your laptop. This method is popular among streamers.
Which Method is Right for Your Setup?
Choosing the best method depends on your goal. For extending your work computer’s display to your laptop for extra screen real estate, the wireless software method is fantastic. It’s convenient and requires no extra purchases. If you want to play a console game on your laptop screen, a wired solution like a capture card will provide the low latency you need for a smooth experience, whereas a wireless connection might have a slight delay.
So, while you can’t just plug an HDMI cable in and expect it to work, you have several powerful options. With a little setup, your laptop can become a very capable second screen, helping you be more productive or simply enjoy your media in a new way.
