Manually Starting a Presentation
If the
Presentations
preference is set to
Enabled
(the default), a presentation starts
automatically during a call if a user connects a video input device other than an
Avaya Video Camera 150, Avaya Video Camera 200, or Avaya Video Camera 100 to the
codec and the video input device is not selected as the primary input. The user interface
switches the presentation input to this video input and starts the presentation. The
presentation stops automatically if the video input device is disconnected during the call.
You can choose
Manual
for the
Auto Start Presentation
preference in
Administrator
Preferences : Communications : General
to allow users to start a presentation manually.
Supported VGA and DVI-I Input Resolutions
Avaya systems support native 16:9 and 4:3 VGA and DVI-I inputs. The
System Information
screen shows the actual VGA or DVI-I input size for
VGA Input
or
DVI-I Input
. The input
selector shows a 16:9 or 4:3 window for the input depending on the aspect ratio.
The resolutions are sent natively to the far end for the primary or secondary video streams.
These resolutions are supported only with a screen refresh rate set to 60 Hertz on the
device connected to the VGA or DVI-I input.
Following are the supported input resolutions and frame rates for video sent to the DVI-I
input from an HDMI source:
•
480p60
•
576p50
•
720p60
•
1080p30 (available only on Avaya systems that support 1080p30 output)
If audio is sent to the DVI-I input from an HDMI source, the audio is sent to the near end
speakers and to the far end when the DVI-I input is selected as the primary or presentation
video input.
For more information about configuring the DVI-I input, refer to
"Configuring HD In and DVI-I In" on page 27.
