cannot add display monitor

Question

cannot add dual display monitor. Laptop does not recognise another monitor. It is plugged into HTML port

Answer 1

Hi,

Are you using an HDMI adapter for the second monitor?

What is the monitor model?

When you connect to the Start menu > Settings > System > Display, does the screen show 1/2?

If so, click the option next to "Identify" and select "Extend".

Have you tried with another HDMI cable to see if it's not a cable fault?

Thanks

If your laptop is not recognizing a dual display monitor that is plugged into the HDMI port, there are a few troubleshooting steps you can try:

1. Check Connections: Ensure that the HDMI cable is securely connected to both the laptop and the monitor. Sometimes a loose connection can cause detection issues.
2. Use Keyboard Shortcuts: Try using the Windows + P keyboard shortcut to toggle through display options. This can help in detecting the external monitor.
3. Display Settings: Go to Display Settings in Windows and click on the Detect button to see if the laptop can find the monitor.
4. Update Drivers: Ensure that your graphics drivers are up to date. Outdated drivers can prevent the laptop from recognizing external displays.
5. Power Options: If you are using a docking station or have specific power settings, make sure that the settings allow for external displays when the laptop lid is closed.
6. Test with Another Monitor: If possible, try connecting a different monitor to see if the issue is with the monitor itself or the laptop.

If these steps do not resolve the issue, it may be beneficial to consult the manufacturer's support or documentation for further assistance.
