USB-C to HDMI adapter plugged in but no picture on the monitor
USB-C to HDMI adapters don't work when the computer's USB-C port doesn't support video output, or the computer is sending video to a different display by default. Unplug the adapter, wait 5 seconds, and plug it back in. This makes the computer re-detect the monitor. If the screen stays black, try forcing the computer to use the external display in your display settings.
Your USB-C to HDMI adapter is a bridge between your computer's port and your monitor's cable. The monitor stays dark when the adapter isn't getting the right signal from the computer, or the computer doesn't know the monitor is there. The problem is that the computer is set to use a different display, the adapter isn't fully recognized, or the USB-C port doesn't support video on your computer.
- ✓Make sure your monitor is powered on and set to the correct HDMI input before starting
- ✓Have access to your computer's display settings — on Windows, right-click the desktop; on Mac, open System Settings
- ✓Have your adapter's model number or documentation on hand in case you need to check compatibility

- Not pushing the adapter or cable in far enough — they need to click completely
- Trying a different adapter before checking if the first one was fully plugged in
- Assuming the adapter is broken when really the monitor is set to the wrong input
