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.

you can see the current settings.
