3. Adjust display settings: Open the display settings on your computer and make sure the correct display is selected as the primary or main display. You may need to adjust the resolution or refresh rate settings to match the capabilities of your monitor.

4. Try a different cable or port: If possible, test the display with a different cable or try connecting it to a different port on your computer. This can help determine if the issue is with the cable or port.

5. Reset display settings: In some cases, resetting the display settings to their default values can resolve the issue. This can typically be done through the display settings or graphics control panel.
