Once the board is powered on and displaying an image, you can control its functions. The board includes a basic menu where you can adjust settings like brightness, contrast, color, and aspect ratio. You can switch between video sources (HDMI or VGA) using the buttons on an optional control panel or remote. The board will automatically detect the input resolution, but it's good practice to ensure your video source is set to a resolution supported by both the driver board and the LCD panel for optimal display quality.

Open the OSD Audio Menu and verify the internal sound level isn't muted. Verify the speaker leads match the load tolerance limits.
