Managing Displays
A display is set up successfully when the color on the display has been adjusted for the lighting in the
meeting room.
Note Each display must be adjusted individually.
Use the information in the following sections to adjust the display for your system:

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
cool, warm, or daylight, but can be expressed more precisely in kelvins (K) as a numeric value.
The following temperatures can be selected for adjusting the image on the Cisco TelePresence display
screens:

•

Tip In many cases, the color temperature is printed on the light bulb. If you are unable to ascertain the type
and color temperature of light bulbs in the meeting room, experiment with color temperature settings
until the color and images on the display screen look lifelike.
It is OK to try a few different color temperatures to see what looks best in the room. Remember, the Color
Tip
Temperature setting only effects how the local participants see the display, it does not effect the way the
room looks to remote participants.
