Some parts of images are off the edge of
the screen (C Series and SX20)
Overscan means that on some parts of the image, menus and soft buttons may be off the edge of the
screen. The recommended fix for this is to go into the menus of the monitor and turn off overscan if
possible. This may be called 'just scan,' '1:1 pixel mapping', 'dot by dot' or something else as name
varies depending on the manufacturer.
if you cannot fix this using the menus on the actual monitor you can use the settings on the web inter-
face. Go to
Configuration -> System Configuration -> Video -> Output
for the interface being used.

Screen does not turn off in standby (HDMI - CEC)
By default the codecs will stop sending any signal when stand-by mode is activated. For some screens
this is fine, they will register they have no signal and after a brief wait they too go into standby mode.
Some screens however will remain on. For HDMi connections you can enable CEC (Consumer Electronics
Control). Depending on the monitor you are using this can also be called something else: Sony: Bravialink,
lG: Simplink, Sharp: Aquos link, pioneer: Kuro link, philips: Easylink, and Samsung: Anynet+.
To do this go to
Configuration -> System Configuration -> Video
see the HDMi interfaces available. You should check that CEC is enabled on your display screens input
as well from the screens menus.
Figure 13 - Enable CEC
NOTE
With some screen manufacturers we find their CEC implementation are non-standard and therefore
even with this setting on the screen will not turn off. lG screens are known to use non-standard CEC
and will not accept our standby signals. DVi connections use a difference signaling method thus screens
connected by the DVi output on the codec to the DVi input on the screen should not have this problem.

Video layout customization
You can create new video layouts on the C60 and C90 codecs and change when to display the
existing layouts on the C40. The easiest method to accomplish this is by using the TC Console tool.
please ensure you have the latest version of TC console by visiting
telepresence-developer/home
The Video Compositor allows you to modify the default video compositing behavior of the codec without
the need for any programming. You can add new layouts, change the automatically selected layouts
and control what will be shown to the user depending on the state of the codec.
New to TC6 is that the custom video layouts will be shown on the Touch interface.
Tip
To see the affects of layout changes live on screen you can enable live layouts. To do this navigate
to
Configure –> Live Layouts
and enable this option.
Settings are not saved onto the codec until the
is then created on the system with the custom layouts and these Api commands are executed upon
startup of the video system.
To see the Api commands for a specific video layout click on the
