9. Consider using a USB-C to HDMI adapter if your device has a USB-C port and the HDMI port is not working.

Updating the Device Driver

To update the device driver for your DisplayPort not working issue in Windows 10, follow these steps:

1. Press Windows Key + X and select Device Manager.
2. Expand the Display adapters section.
3. Right-click on your display adapter and select Update driver.
4. Choose “Search automatically for updated driver software.”
5. Windows will search for the latest driver and install it if available.

7. Restart your PC after the driver update.

Updating your device driver can often resolve display issues and ensure optimal performance.

python
import subprocess

def check_dp_status():
# Use subprocess to run the command 'dxdiag' and capture the output
result = subprocess.run(['dxdiag'], capture_output=True, text=True)

# Check if DisplayPort is mentioned in the output
if 'DisplayPort' in result.stdout:
return 'DisplayPort is working properly.'
else:
return 'DisplayPort may not be working.'

def main():
dp_status = check_dp_status()
print(dp_status)

if __name__ == '__main__':
main()

In this sample code, the `check_dp_status()` function uses the `subprocess` module to run the ‘dxdiag’ command, which provides system information including display information. It captures the output and checks if ‘DisplayPort’ is mentioned in the output. Based on the presence or absence of this information, it returns a corresponding message indicating whether the DisplayPort may or may not be working.

Changing the Refresh Rate on the Monitor

To change the refresh rate on your monitor, follow these steps:

1. Right-click on your desktop and select “Display settings.”
2. Scroll down and click on “Advanced display settings.”
3. Under the “Refresh rate” dropdown menu, select the desired refresh rate (e.g., 144Hz).
4. Click “Apply” to save the changes.

If you’re experiencing a display port not working issue, try these troubleshooting methods:

1. Check the cable connection to ensure it’s securely plugged in.
2. Update your graphics driver to the latest version.
3. Restart your computer and monitor.
4. Try using a different display port or cable.
5. Test the monitor on another computer to rule out hardware issues.
