LifeSize Video Communications Systems User Guide 35
Display Issues
The following issues are related to the user interface or the display.
Display Failures
If data does not appear on the display, ensure cables are properly connected on the display
and that the display cable is connected to the Display 1 output on the back panel of the
codec. Also ensure you have selected the correct input. Refer to “Selecting Input” on
page 23 for more information.
If the video image and user interface appear washed out or too bright, examine the input
settings of your HDTV to make sure the HDTV is displaying the appropriate resolution.
Some HDTVs (particularly plasma displays) allow you to configure the native resolution of
the input device from the HDTV administration interface.
If you are using a second display with LifeSize Room and nothing appears or you see data
from only one input, you may be using an unsupported display or the secondary input is
turned off. Navigate to User Preferences : Appearance : Secondary Display Layout. If
this preference is disabled and you are unable to modify it, you are using an unsupported
display. Otherwise, ensure that the VGA input for the second display is connected.
Poor Quality Display
If you have poor quality or unreadable data on the phone display, adjust the User
Preferences : Appearance : LCD Contrast setting. LifeSize recommends using the default
setting (6).
If the colors on the display appear incorrect, verify that the RGB cable is properly connected
to the display.
Missing Input
If you have not connected all possible video inputs, the input selection dialog displays a
black image by default. Connect the necessary input or choose a different input as
described in “Selecting Input” on page 23.
Poor Quality Far End Video
During a call, the LifeSize system automatically selects the best video algorithm based on
the video source and capabilities of the remote system. If you experience poor motion
handling or visible tiling in the far end picture during a video call, contact your administrator.
