What needs to be manually adjusted when using component video output?

When using component video output, it is essential to manually adjust the vertical resolution, scan method, and aspect ratio because these settings directly influence how the video signal is processed and displayed on the screen. Component video splits the video signal into multiple parts to enhance quality, and without configuring these settings, the video might not display correctly or optimally on the output device.

Adjusting vertical resolution ensures that the video content fits properly on the screen without distortion. The scan method determines how the image is rendered—progressive or interlaced—which affects the smoothness and clarity of motion. Additionally, the aspect ratio is crucial for maintaining the intended proportionality of the image, preventing stretching or compression of the video content.

The other options relate to different systems' operational aspects and do not impact the component video output directly. Audio settings pertain to sound rather than video, while network settings and configurations deal with connectivity issues, and power settings address energy consumption but do not influence video quality.
