5. Operating Instructions
Once all connections are made and devices are powered on, the adapter should automatically convert the HDMI signal to VGA. You may need to adjust settings on your source device or display:
- Display Input Selection: On your VGA display or projector, select the correct VGA input source.
- Resolution Adjustment: The adapter supports resolutions up to 1920x1080. If the display is not optimal, adjust the display resolution settings on your source device to match the native resolution of your VGA display or a supported resolution by the adapter.
- Audio Output: If using the 3.5mm audio output, ensure that your source device's audio output is set to HDMI (which the adapter will then convert to analog audio). You may also need to adjust volume levels on your source device or connected speakers.
- HDCP Content: Please note that this HDMI to VGA adapter does not support devices that require High-bandwidth Digital Content Protection (HDCP) for viewing copyrighted content, such as some DVD or Blu-Ray players. Attempting to play HDCP-protected content may result in a blank screen or no signal.

6. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
- No Video Signal / Blank Screen:
- Ensure all cables (HDMI, VGA, optional USB power) are securely connected.
- Verify that the VGA display is powered on and set to the correct VGA input source.
- Try connecting the optional USB power cable to the adapter, especially if using a device with low HDMI power output (e.g., MacBook Pro, Raspberry Pi).
- Adjust the display settings on your HDMI source device (e.g., extend display, duplicate display, change resolution).
- If using a Raspberry Pi, you may need to modify the
config.txtfile (e.g., sethdmi_force_hotplug=1) to ensure HDMI output. - Confirm that the content you are trying to display is not HDCP-protected.
- No Audio Output:
- Ensure the 3.5mm audio cable is securely connected to both the adapter and your speakers/headphones.
- Check the audio output settings on your HDMI source device to ensure audio is routed through HDMI.
- Verify that your speakers or headphones are powered on and their volume is turned up.
- Test with different speakers or headphones to rule out a faulty audio device.
- Flickering or Distorted Image:
- Ensure the optional USB power cable is connected to the adapter and a reliable power source.
- Try a different VGA cable.
- Adjust the resolution on your source device to a lower setting or a standard resolution supported by your VGA display.
