To troubleshoot the issue with your portable monitor not displaying any signal when connected via USB-C and HDMI, you can follow these steps:
- Check Cable Connections: Ensure that both the HDMI and USB-C cables are securely connected to both the monitor and your computer. Sometimes, a loose connection can cause no signal issues.
- Test Different Ports: If your computer has multiple HDMI or USB-C ports, try connecting the monitor to a different port to see if that resolves the issue.
- Check Monitor Input Settings: Make sure that the portable monitor is set to the correct input source. Some monitors have multiple input options and may need to be switched to the HDMI or USB-C input manually.
- Verify Compatibility: Ensure that your portable monitor is compatible with your computer's output settings. Check the specifications of both devices to confirm they support the same resolutions and refresh rates.
- Update Drivers: Ensure that your graphics drivers are up to date. You can check for updates through the Device Manager in Windows.
- Use a Different Cable: If possible, try using a different HDMI or USB-C cable to rule out a faulty cable.
- Check Display Settings: On your computer, right-click on the desktop and select "Display settings". Make sure that the monitor is detected and configured correctly. You can also try pressing Windows + P to switch between display modes (e.g., Extend, Duplicate).
If none of these steps resolve the issue, there may be a hardware problem with either the monitor or the computer's ports.
