How do I troubleshoot if my Mini PC shows 'No Signal', screen flickering, or resolution issues after connecting to a monitor?

1. Signal & Connections

Make sure you're using the original or a high-quality video cable, as poor-quality cables often cause flickering or "No Signal" errors. When troubleshooting, prioritize a direct connection to the monitor—avoid using adapters or docking stations—and double-check that the monitor is set to the correct input source.

2. Display Settings

Once in the system, right-click the desktop to open Display Settings, then adjust the resolution and refresh rate to the monitor's recommended values. Updating your integrated graphics driver is also crucial to fix resolution glitches or screen lag.

3. Multi-Screen Troubleshooting

For multi-monitor setups, enable "Duplicate" or "Extend" mode in Display Settings. Verify that the Mini PC's video ports are outputting correctly, and isolate the issue by testing each screen individually.
