If your laptop is not recognizing external monitors, there are several troubleshooting steps to identify and resolve the issue:

Check Physical Connections: Ensure that the cables connecting your laptop to the external monitor are securely plugged in. Try using different cables to rule out potential issues with the connection.

Monitor Input Source: Confirm that the external monitor is set to the correct input source. Some monitors have multiple input options, such as HDMI, DisplayPort, or VGA.

Update Graphics Drivers: Outdated or incompatible graphics drivers can cause recognition issues. Visit the manufacturer's website or use the device manager to update your graphics drivers to the latest version.

Windows Display Settings: Right-click on the desktop, select "Display Settings," and check if the external monitor is detected. You can extend or duplicate displays based on your preferences.

Try Another Monitor: If possible, connect your laptop to another external monitor. This helps determine if the issue lies with the laptop, the monitor, or the cables.

Restart Your Laptop: Sometimes, a simple restart can resolve software glitches that may be affecting the recognition of external monitors.

BIOS/UEFI Settings: Check your laptop's BIOS/UEFI settings to ensure that external display options are enabled.

If these steps don't resolve the issue, consulting your laptop's user manual or seeking assistance from the manufacturer's support can provide further guidance in resolving the problem.
