Try to mount your Media Player where it can be best seen by your audience. Watch out for windows causing glare, or other obstructions such as poles and walls that will limit viewing radius.
Take advantage of high traffic areas and consider locations where your audience is queued or waiting for any length of time. Areas such as checkout lines, baggage claims, waiting rooms, lobbies, etc. are perfect locations to position your display. Screens are available in various sizes. With that in mind, take note of the distance between the panel and audience and use an appropriate sized display. Flat panel displays suffer from viewing angle limitations. CRT’s radiate light roughly into a full hemisphere, while flat panel devices radiate light over a smaller solid angle that is highly directional. Consequently, moving the head or tilting the display changes contrast, brightness, and colors of the screen in a dramatic way.
