How to Set Laptop Display to HDMI Input?

Setting your laptop display to HDMI input can be extremely useful when you want to enjoy media content on a larger screen or make a presentation. It allows you to connect your laptop to a TV, projector, or any other HDMI compatible device. In this article, we will guide you through the steps to set your laptop display to HDMI input seamlessly.

Before we jump into the steps, check if your laptop has an HDMI port. Most laptops manufactured in the past decade feature an HDMI port, neatly situated on the side or back of the device. This port looks similar to a regular USB port but has a slightly wider shape. Once you have confirmed that your laptop has an HDMI port, follow these straightforward steps:

1. **Connect the HDMI cable**: Begin by connecting one end of the HDMI cable to the HDMI port on your laptop and the other end to the HDMI input port on the device you want to connect it to, such as a TV or projector.

2. **Switch on the external device**: Once both ends of the HDMI cable are securely connected, switch on the TV or projector to which you have connected your laptop.

3. **Select the correct input source**: Use the remote control or the buttons on the device to select the correct HDMI input source. If you are unsure which HDMI input to choose, consult the user manual of your TV or projector.

4. **Adjust display settings on the laptop**: On your laptop, go to the “Display Settings” panel. You can access this panel by right-clicking on the desktop and selecting “Display Settings” or by navigating through the control panel or settings menu, depending on your operating system.

5. **Detect external display**: In the display settings, look for an option called “Detect” or “Identify.” Click on this option to let your laptop recognize the external display.

6. **Select display mode**: Decide how you want the display to appear on the external device. You usually have three options: “Duplicate these displays” (mirror mode), “Extend these displays” (extended mode), or “Show only on 1” or “Show only on 2” (using the external display as your primary display).

7. **Set resolution**: Adjust the resolution settings to ensure the display looks best on the external device. Select the resolution that matches your TV or projector’s recommended resolution for optimal output.

8. **Apply the changes**: After making the necessary adjustments, click “Apply” or “OK” to save the settings and activate the HDMI input on your laptop.

Setting your laptop display to HDMI input should now be complete, and you should be able to see your laptop screen on the external device. Enjoy your media content or present your work on a larger screen with ease.


1. Can I connect my laptop to an HDMI device if it doesn’t have an HDMI port?

No, you cannot directly connect your laptop to an HDMI device without an HDMI port. However, there are adapters available that convert other ports like USB-C or VGA to HDMI, allowing you to establish a connection.

2. Why isn’t my laptop detecting the external display?

Ensure that you have correctly connected the HDMI cable and that the external device is switched on. Also, check if the HDMI cable is in good condition, as a faulty cable can prevent the laptop from detecting the display.

3. Is it possible to connect multiple external displays through HDMI?

Yes, some laptops support multiple HDMI outputs, allowing you to connect multiple external displays simultaneously. However, please note that not all laptops have this capability.

4. Can I use an HDMI splitter to connect my laptop to multiple devices?

Yes, an HDMI splitter allows you to connect one HDMI output from your laptop to multiple HDMI devices, such as TVs or projectors. This enables you to display the same content on multiple displays simultaneously.

5. Why is there no sound on my external display after connecting via HDMI?

Sometimes, the audio output default may remain set to your laptop’s speakers instead of the external display. To resolve this, go to the sound settings on your laptop and change the output device to the external display.

6. What should I do if the display appears distorted on the external device?

Double-check the resolution settings on your laptop and set it to match the recommended resolution of the external device. This should help rectify any distortion issues.

7. Can I disconnect the HDMI cable while my laptop is still running?

It’s recommended to turn off your laptop before disconnecting the HDMI cable. This ensures that both the laptop and the external device are disconnected properly and reduces the risk of data loss or hardware damage.

8. Do all laptops support HDMI-CEC?

No, not all laptops support HDMI-CEC (Consumer Electronics Control), which allows you to control multiple HDMI devices with a single remote control. It’s advisable to check your laptop’s specifications to confirm if it supports HDMI-CEC.

9. What if my laptop’s screen goes black when connected via HDMI?

Check the HDMI cable, as a loose or damaged cable can cause display issues. Additionally, ensure that the display settings on your laptop are correctly set to extend or duplicate the screen on the external display.

10. Can I connect a gaming console to my laptop’s HDMI input?

No, laptops don’t typically have an HDMI input. The HDMI port on laptops is usually an output port, allowing you to connect your laptop to external displays, not vice versa.

11. Can I adjust the screen resolution on the external display?

Yes, you can adjust the screen resolution on the external display. Refer to the user manual of the device or access the display settings on the external device to make the necessary adjustments.

12. How do I switch back to my laptop’s screen from HDMI input?

To switch back to your laptop’s screen, simply change the display mode to “Show only on 1” (Windows) or “Mirror Displays” (Mac) in the display settings. This will disable the HDMI input and revert to using your laptop’s screen as the primary display.
