Sharpness and motion settings
You can check this setting
Configuration -> System Configuration -> Video -> Input -> SourceX -> Quality
(X is the source number for the presentation source). For presentations this should be set to Sharpness
rather than Motion. This prioritizes the video resolution over frame rate which is the default setting for
presentation inputs and the preferred setting.
NOTE
Camera sources should be set to motion.
Allocation of bandwidth for presentation
The available transmit video bandwidth (call rate) is distributed between the main channel (camera) and
presentation channel according to MainChannel Weight and PresentationChannel Weight values. These
can be changed under
Configuration -> System Configuration -> Conference 1 -> Video Bandwidth.
The more bandwidth allocated to a channel, the better the image from that channel will be. This way
you can prioritize your presentations over the camera video if needed.
For example if the presentation channel weight is set to 2 and the main channel weight is 1, then the
presentation channel will use twice as much bandwidth as the main (camera) channel.
The
Configuration -> System Configuration -> Conference 1 -> Video Bandwidth -> Mode
dynamic or static. if set to dynamic (default setting) the system will use all the available call bandwidth
until a presentation is started whereupon it will change the bandwidth to those defined above. if set
to static the presentation bandwidth will be reserved even when no presentation is being shown. The
recommendation is to set this to dynamic to utilize all bandwidth during the call.
Using multiple screens
To have output on a second screen on C20, C40, SX20 and EX90 adual display option key is needed. C60
and C90 do not need this key, as all outputs are enabled by default. please see "Option keys" on page 27
for more information about the dual display option key and how to check which keys you have currently
installed.

Menus – On Screen Display (OSD)
Cannot see the menus on current screen
On the C Series the menu is displayed on one monitor output only. On the other outputs you
will only see the background image. To check the menu settings using web interface go to
Configuration -> System Configuration -> Video
can be set to
Figure 9 – Menu Settings
From here you can see if the menus are enabled (Mode – On) and which physical output the menus
are sent to.
You can check which physical output the Output number is referencing by checking the
(see below) or checking the physical backplane of the system.

NOTE
You will not see on screen menus when using a Touch panel that is correctly paired to the video
system, they are only available for users using the remote control.
