Selecting the Light Level
When adjusting the images on the CTS display screens, you must take the color temperature of the
ambient light in the room into consideration.
Sources of light in most rooms are produced by fluorescent fixtures or incandescent light bulbs that use
tungsten filaments. Each of these light sources, and the amount of light in terms of lumens or watts,
produces a different color temperature. This color temperature is sometimes expressed using terms such
