A USB Parallel adapter has many different functions but the most commonly thought of function is plugging into a Desktop tower so that your monitor may work and be hooked up to a graphics card. Without being plugged into a graphics card, your monitor has nothing to display and doesn’t have the firmware to display any of the visuals. Most of the graphics you can see and process will be solely dependent on your graphics card.

Every monitor that initially gets plugged into a computer, it will then start to scan internally (only if the computer is turned on of course) for software or firmware inside of the computer. Once the computer returns the information back, it then determines the screen size and what kind of monitor it is so it knows exactly what kind of information to display. Of course there’s a lot of other elements at work such as the MS rat of the monitor and etc, but that’s the important stuff.
