Why is my laptop not recognizing my external monitor?

1. Check the connectivity port of your laptop and make sure your external monitor cable is securely connected to that port.
2. Check your monitor’s power cable and make sure that it is plugged into an active outlet.
3. Check your laptop to see if the settings are configured correctly. In the 'display settings' you might need to set the display to 'dual'.
4. C heck your laptop's Display adapter settings to make sure your laptop is using the correct graphics driver.
5. Uninstall and reinstall your graphics driver and reboot your laptop.
6. Check your laptop's BIOS settings to see if external monitor display is enabled.
