How to Duplicate Laptop to Monitor?

Duplicating your laptop screen onto a monitor is a straightforward task. Just follow these simple steps:

1. Check your laptop’s video output: Look for the video ports on your laptop, which commonly include HDMI, DisplayPort, VGA, or DVI. Note the type of port available as it will determine the necessary cables.

2. Check the monitor’s video input: Similarly, identify the video inputs on your monitor. The most common inputs are HDMI, DisplayPort, DVI, and VGA. Ensure your monitor has a compatible video input.

3. Connect the cables: Use the appropriate cable to connect your laptop’s video output to the monitor’s video input. For example, if your laptop has an HDMI output, use an HDMI cable to connect it to the HDMI input on the monitor.

4. Turn on your laptop and monitor: Once all the cables are securely connected, power on your laptop and monitor.

5. Access display settings: On your laptop, right-click on any empty area of the desktop and select “Display settings” or “Graphics options.”

6. Identify the display settings: In the display settings window, locate the “Multiple displays” section. Here, you can choose how you want your laptop and monitor to function together.

7. Select duplicate display: In the multiple displays section, select the option to duplicate or mirror the displays. This will ensure that what is shown on your laptop screen is replicated on the external monitor.

8. Apply the changes: Click on the “Apply” button to save the display settings. Your laptop’s screen should now be duplicated on the monitor.

9. Adjust the resolution: If the display on the external monitor appears distorted or improperly sized, you may need to adjust the resolution. Return to the display settings window and modify the resolution until the display appears correctly.

And voila! Your laptop screen is successfully duplicated on the external monitor, enabling you to enjoy a larger workspace and improved productivity.
