Configuring VGA Output
Automatic configuration of VGA displays may not detect all displays. The following
conditions may occur with some VGA monitors:
• Failure to read the Extended Display Identification Data (EDID) of the display.
LifeSize Room detects the display as VGA, but cannot determine its supported
resolutions. LifeSize Room configures the display output to VGA at 1280x768. EDID is
a VESA standard data format that contains general information about a display and its
capabilities, including vendor information, maximum image size, color characteristics,
factory pre-set timings, frequency range limits, and character strings for the display
name and serial number.
• Failure to detect the display as a VGA device.
LifeSize Room configures the output to 720p. Most VGA monitors display this signal,
however, the data is not centered and may be tinted green. You must manually
configure the appropriate display as VGA to resolve this issue.
• The resolution of the display is unsupported.
LifeSize Room is a high definition video conferencing system that requires displays that
support 1280x720 or 1280x768 resolutions. If a VGA display EDID does not contain one
of these resolutions, LifeSize Room automatically configures it for 1280x768. Most
multi-sync VGA displays can adjust to this resolution and scale the data to fit the screen,
which is typically 4x3. If scaling occurs, the resulting image may be slightly distorted. For
example, a display that only supports 1024x768 will scale the 1280x768 image causing
it to appear narrow. If a display cannot adjust to the 1280x768 resolution, its screen
remains blank or a message displays indicating the resolution is not supported. LifeSize
Room does not support displays that do not support 1280x768.
When LifeSize Room does not automatically address one of these conditions, you must
manually configure the display output. You can configure the display output from the
LifeSize Room onscreen interface or from the LCD interface on the LifeSize Phone
connected to your LifeSize Room system as described in the following sections.
Configuring Display Output from LifeSize Room
If your LifeSize Room system displays the initial configuration screen or the display is not
showing an image, you must configure the display from the LifeSize Phone. Refer to
"Configuring Display Output from LifeSize Phone" on page 30.
