Can You Connect Two Laptops Via HDMI?

Yes, it is possible to connect two laptops via HDMI. HDMI (High-Definition Multimedia Interface) is a digital audio/video interface that allows you to transmit high-quality video and audio signals between devices. By connecting two laptops via HDMI, you can extend the display of one laptop to the other, share screens for collaboration, or transfer files.

Step-by-Step Instructions

  1. Gather your equipment: You will need an HDMI cable and two laptops with HDMI ports.
  2. Connect the HDMI cable: Plug one end of the HDMI cable into the HDMI port on one laptop and the other end into the HDMI port on the second laptop.
  3. Adjust display settings: On the laptop you want to extend or share the screen from, go to the display settings. Select the option to “Extend display” or “Duplicate display.”
  4. Configure audio output (optional): If you want to transmit audio along with the video signal, you may need to configure the audio output settings on both laptops. Go to the sound settings and select the HDMI output as the default audio device.


  • No signal detected: Ensure that the HDMI cable is properly connected to both laptops and that the laptops are powered on.
  • Incorrect display settings: Verify that the display settings on both laptops are configured correctly for HDMI output.
  • Outdated drivers: Update the graphics drivers on both laptops to ensure compatibility.
  • Damaged HDMI cable or port: Try using a different HDMI cable or connecting to different HDMI ports on the laptops.

Alternative Methods

In addition to HDMI, there are other methods to connect two laptops for screen sharing or file transfer:

  • Network sharing: Connect both laptops to the same Wi-Fi network and use file-sharing software or cloud storage services to transfer files.
  • USB-C with DisplayPort Alt Mode: If both laptops have USB-C ports with DisplayPort Alt Mode, you can use a USB-C to USB-C cable to connect them and extend or mirror screens.
  • Wireless screen sharing software: Install screen sharing software on both laptops and use Wi-Fi to connect them for remote screen viewing and control.


Connecting two laptops via HDMI is a straightforward process that allows you to extend your display, collaborate on projects, or transfer files. By following the step-by-step instructions and troubleshooting tips, you can establish a successful HDMI connection between your laptops. Remember, there are also alternative methods available if HDMI is not an option.
