4. OPERATIONS
This monitor works in conjunction with a DVD player or other video source mounted
usually in the dashboard of your car. Headphones provide the audio.
If your car is equipped with more than one audio/video source, such as a DVD and a
game player, one person can watch a movie the other plays the game. The output from
one video source displays in the main window and the output from the second video
source either displays in a sub window, or the screen splits into two equal-sized
pictures (split screen).
