Can You Use a Laptop Screen as a Monitor?
How to Convert Laptop Screen to Monitor: Yes, you can, but it’s not as straightforward as connecting a regular external monitor. A laptop’s screen is designed to work as part of a fully integrated system, meaning it doesn’t have a standard HDMI input like traditional monitors. However, with the right software, hardware, or settings, you can successfully use your laptop as a secondary display.

Methods to Convert a Laptop Screen into a Monitor
1. Using Windows Built-in Features (For Windows 10 & 11)
How to Convert Laptop Screen to Monitor: If you want to use your laptop as a second display for another Windows PC, you can use the built-in Wireless Display feature. Here’s how:
- On the laptop you want to use as a monitor, go to Settings > System > Projecting to this PC
- Under Some Windows and Android devices can project to this PC, select Available everywhere
- On the primary PC (the one you want to extend from), press Windows + P and select Connect to a wireless display
- Choose your laptop from the list and select Extend to use it as a second monitor
This method works only if both devices support Miracast. If your laptop doesn’t support Miracast, you might need to use third-party software.
2. Using Third-Party Software
If your devices don’t support Wireless Display, you can use third-party apps like:
- SpaceDesk (Best for Windows users)
- Duet Display (Works with Mac and iPad as well)
- Splashtop Wired XDisplay (For wired connections)
To use these:
- Download and install the software on both devices
- Follow the on-screen instructions to connect them via WiFi or USB
- Configure display settings to extend or mirror the screen
These apps allow smooth screen sharing, with some offering touchscreen support if your laptop has a touchscreen.
3. Using an HDMI Capture Card
If you want to use your laptop’s screen for devices like a gaming console, Raspberry Pi, or another PC without software-based limitations, an HDMI capture card is a great option. Here’s how:
- Connect the HDMI output of the source device to the HDMI input of the capture card
- Plug the capture card into your laptop’s USB port
- Install and open OBS Studio (a free streaming software)
- Add a Video Capture Device source in OBS to display the HDMI input
How to Convert Laptop Screen to Monitor: While this setup isn’t as seamless as using a dedicated monitor, it’s an effective way to display external video sources on your laptop screen.
4. Using Remote Desktop Software (For Controlling Another PC)
If your goal is to control another PC from your laptop, you can use remote desktop software like:
- Microsoft Remote Desktop (For Windows-to-Windows)
- Chrome Remote Desktop (Works on all platforms)
- AnyDesk or TeamViewer (For professional remote access)
How to Convert Laptop Screen to Monitor: Simply install the software on both devices, log in, and start controlling the other PC remotely. While this doesn’t make your laptop a true “monitor,” it allows you to access another system seamlessly.
Which Method is Best for You?
- If you’re extending your Windows PC screen, use Windows Wireless Display
- If you need a software-based solution, apps like SpaceDesk or Duet Display are ideal
- If you want to connect gaming consoles or other external devices, an HDMI capture card is the way to go
- If you need remote access, try Microsoft Remote Desktop or Chrome Remote Desktop
