How to make laptop second monitor?

Hardware Approach:

  1. What You Need to make laptop second monitor:
    • A laptop with a special port that can take in video signals (like HDMI, DisplayPort, or VGA).
    • Another device (like a desktop PC) with a matching port that can send out video signals.
    • A cable or adapter that connects the two devices together.
  2. How to Connect:
    • Look for the right port on your laptop and the matching port on the other device.
    • Get a cable that fits both ports (like an HDMI cable if both devices have HDMI ports).
    • Turn off both devices.
    • Plug one end of the cable into the output port on the other device and the other end into the input port on your laptop.
    • Turn both devices back on.
  3. Configuring the Connection:
    • Once both devices are on, you may need to set up the connection.
    • On your laptop, you might have to go into the display settings (usually found in the control panel or system preferences).
    • Look for an option to detect or extend displays.
    • Follow any on-screen prompts to finish setting up the connection.
  4. Using Your Laptop as a Secondary Display:
    • Once the connection is set up, your laptop should act like a second screen.
    • You can now move windows between the two screens, extend your desktop, or use the laptop screen for specific tasks while still using your primary device.

Software Approach to make laptop second monitor::

  1. What You Need:
    • Software that can extend or duplicate your desktop onto your laptop screen.
    • This software might work over Wi-Fi or through a direct cable connection.
  2. Setting Up the Software:
    • Install the software on both your laptop and the other device.
    • Follow the instructions provided by the software to set up the connection between the two devices.
    • This might involve configuring settings on both devices and ensuring they’re connected to the same network (if using Wi-Fi).
  3. Using Your Laptop as a Secondary Display:
    • Once the software is set up, your laptop should function as a secondary display.
    • You can now use it alongside your primary device, just like you would with a physical secondary monitor.


Whether you’re using a hardware or software approach, turning your laptop into a secondary display can give you extra screen space and improve your productivity. Choose the method that best fits your needs and equipment!
