Setting Up the Displays
A display is set up correctly when the color on the display has been adjusted for the lighting in the
meeting room. Each display must be set up individually.
To set up the display, complete the following steps:
Step 1 In the Cisco TelePresence administrative GUI, navigate to Hardware Setup > Troubleshooting >
Displays.
Step 2 Click Start to begin the adjustment process.
Each display in the meeting room should now be showing a set of horizontal grey bars and that display's
relative position.
Step 3 Select the color temperature of the lighting in the meeting room and click Apply.
For more information about selecting the correct lighting temperature, see the “Selecting the Light
Level” section on page 10-5 .
Selecting the Light Level
When adjusting the images on the display screens for the Cisco TelePresence system, you must take the
color temperature of the ambient light in the room into consideration.
Sources of light in most rooms are either incandescent light bulbs that use tungsten filaments or
fluorescent lights. 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.
Following are the temperatures that can be selected for adjusting the image on the Cisco TelePresence
display screens:
• 3500 K
• 4000 to 4100 K (recommended setting)
• 5000 K
• 6500 K
• 7500 K
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.
Troubleshooting Displays
Use Table 10-1 to troubleshoot problems with the images on the displays.
