When testing a new AV setup, which adjustment is typically verified first?

1. Audio output levels

2. Signal strength of the connection

3. Brightness and contrast settings

4. Physical alignment of equipment

The correct answer is: Brightness and contrast settings

When testing a new AV setup, the first adjustment that is typically verified is the brightness and contrast settings. This is crucial because the visual display is often the most immediately noticeable aspect of an AV system. Ensuring that the image is properly calibrated in terms of brightness and contrast is essential for an optimal viewing experience. This adjustment allows the user to see how well the system performs visually in the intended environment, as lighting conditions can greatly affect screen performance. Once the visual settings meet the demands of the environment, other elements like audio output levels, signal strength, and physical alignment can be addressed to ensure a comprehensive setup. However, establishing the right brightness and contrast often sets the stage for assessing the overall video quality and user experience.
