Why does your monitor have a video on it when not in use?

I assume you are talking about the screen saver. In "traditional" monitors, the large bulky ones that are CRT or Cathode Ray Tubes they were sensitive to a stationary image being displayed too long. An image left stationary would 'burn' an image into the screen and effectively ruin the monitor. Screen savers were developed so that when left with a stationary image for a certain amount of time it would put up another moving image to preserve the monitor. Newer LCD or flat screen monitors don't need this as they use an entirely different process. Newer screens no longer need Screen Savers, but are kept largely for aesthetic reasons.

Can you use only the vga connector for your monitor?

Yes, you would use only one of the video connectors at a time. The reason some monitors have different video connectors is to allow it to connect to a number of different video cards. If you have a DVI or HDMI connector on both the motherboard or video card and the monitor, then use it, and if not, use the VGA connector. Just use the one that is on both the computer and the monitor, and if you have both, just use the one you prefer.
