If the Samsung C32F39MFU monitor displays a grey screen and shows a cable error message, take the following troubleshooting steps:

1. Check Power Connection: Ensure the power cable is properly connected.
2. Check Video Cable: Verify that the video cable is securely connected to both the monitor and the source device.
3. Confirm Supported Resolution/Frequency: Make sure the output resolution and frequency from the source device do not exceed the monitor's supported specifications.
4. Adjust Source Device Settings: Change the resolution and refresh rate on the source device to match the monitor's supported modes.
5. Use Compatible Cables: Ensure the cable type is compatible and functioning properly.

If the issue persists, try using a different cable or source device to isolate the problem.
