- Cable Issues: The cable might be defective or not fully compatible with your device.
Solutions:
- Check Device Specifications: Confirm that your device’s USB-C port supports video output.
- Try a Different Cable: Test with another USB C to HDMI cable to determine if the issue is with the cable.
6. Cable Getting Hot
Possible Causes:
- Cable Quality: Poorly made cables may overheat during use.

7. Device Overheating
Possible Causes:
- Incompatible Cable: Some cables might cause excessive strain on your device’s port.
- Power Draw: High-power cables might draw more power than your device can comfortably handle.
Solutions:
- Use a Certified Cable: Ensure the cable is from a reputable manufacturer and is compatible with your device.
- Disconnect When Not in Use: Remove the cable when it’s not needed to prevent unnecessary power draw and heat buildup.
Conclusion
Troubleshooting USB C to HDMI cable issues involves checking connections, verifying cable quality, adjusting settings, and ensuring compatibility.
