It seems you are experiencing issues with your second monitor not functioning properly on your Helios Predator PH315-52 notebook. Since you have already tested the notebook with Linux and other monitors, it does suggest a potential hardware issue. Here are a few troubleshooting steps to consider:
- Check Connections: Ensure that all cables are securely connected and that there are no visible damages to the ports or cables.
- Display Settings: Use the Windows + P keys to toggle through the display modes (Duplicate, Extend, Second screen only) and see if the monitor responds.
- Update Drivers: Make sure that your graphics drivers are up to date. You can do this through the Device Manager in Windows.
- Test with Different Ports: If your notebook has multiple output ports (HDMI, DisplayPort, etc.), try connecting the monitor using a different port.
- Monitor Power: Ensure that the second monitor is powered on and functioning correctly by testing it with another device if possible.
- Hardware Diagnostics: If available, run any built-in hardware diagnostics provided by your notebook manufacturer to check for hardware issues.
If none of these steps resolve the issue, it may indeed indicate a hardware failure that could require professional repair or replacement.
