The issue can be in either the driver or the physical connection. If your computer is not detecting the second monitor, it is usually an issue with the driver. However, it might also be a physical connection problem. You can try these troubleshooting tips to start with before tampering with the system settings:
- Check that the monitor is plugged into a power source and make sure the display is turned on.
- Power off the computer and restart it to refresh the connection.
- Confirm the signal cable connection between the computer and monitor.
- Locate the display controls and switch to the correct input port.
- Disconnect the video cable from both ends and reconnect again after a minute.
- Connect a different video cable to discard a problem with the cable.
- Change ports if the monitor and graphics card have different ports.
- Display Port and HDMI cables have different variations. Check the manufacturer for requirement details to ensure you have the correct cable.
- Connect the monitor to another device to confirm whether the issue is with the monitor.
- Connect another known working monitor to determine if the issue isn’t the graphics card.
- Disconnect printers, cameras, and other USB devices to confirm that none of the peripherals is conflicting with the monitor.
- Update the external monitor firmware to help fix bugs and compatibility issues (uncommon).
After trying the above troubleshooting steps, if you still have issues, the problem may be software-related.
