If your USB-C to HDMI cable isn't working, it might be due to several factors. First, ensure your device supports HDMI output through USB-C, as not all devices do. Check the cable for any physical damage and try a different cable to rule out a defective one. Ensure your adapter is fully plugged in on both ends. Update your device's software and drivers, as outdated software can cause compatibility issues. Additionally, try connecting to a different HDMI port on your monitor or TV. If none of these steps work, your device or adapter might be faulty.
