You’re looking at your laptop and then at a separate device, like a gaming console or another computer, and a question pops into your head: can I use this laptop as a screen? It’s a common thought, especially when you want a larger or more convenient display without buying a new monitor. The short answer is yes, but it’s not always as simple as plugging in a cable.
Your laptop is designed as a complete system, so its video port is typically an output for sending a signal to a bigger monitor, not an input for receiving one. However, with the right software and a few tricks, you can absolutely repurpose that laptop screen for other devices.
Using Your Laptop as a Second Monitor for Another PC
This is one of the most popular scenarios. If you have a desktop PC and a laptop, you can extend your desktop’s display onto the laptop screen. This doesn’t use any physical cables between the machines. Instead, you use built-in features in Windows or free third-party software. The built-in Projecting to this PC feature in Windows 10 and 11 allows another Windows machine to project to it wirelessly. For cross-platform use or a more robust connection, software like spacedesk works very well.
Connecting a Gaming Console or Streaming Stick
You might wonder if you can plug a PlayStation, Nintendo Switch, or Amazon Fire Stick directly into your laptop. Unfortunately, this usually isn’t possible because of that lack of a video input port we mentioned. A potential workaround involves using a capture card. This small device acts as a bridge, taking the HDMI signal from your console and feeding it to your laptop via USB, where special software displays it. It’s an extra step and a small cost, but it makes it work.
Simple Software Solutions for Screen Sharing
For everyday tasks, you might not need any hardware at all. If you just want to see your phone’s screen on your laptop, both Android and iOS have built-in screen mirroring options that work over Wi-Fi. Similarly, remote desktop applications like Chrome Remote Desktop or TeamViewer let you access and control one computer from your laptop, effectively turning the laptop into a window for that other machine.
So, while your laptop might not have a simple “HDMI-in” port, you have several powerful and often free methods to use it as a screen. Whether for boosting productivity with a second monitor or viewing content from another device, a solution is likely just a few clicks away.
