Operating Instructions
Once all connections are made and your display is set to the correct HDMI input, your computer's display should appear on the connected monitor or TV. The adapter supports various resolutions up to 1080p (1920x1080) Full HD. Ensure your computer's display settings are configured to a resolution supported by both the adapter and your display.
- Video Resolution: The adapter automatically scales the VGA input to the optimal HDMI output resolution, up to 1080p. If the display is blank, try adjusting your computer's display resolution to a common setting like 1024x768 or 1280x720, then gradually increase it.
- Audio Output: As configured during setup, audio from your computer will be transmitted through the USB connection to the adapter and then embedded into the HDMI signal. Adjust volume directly on your display or through your computer's sound settings.
