10.2.3. SDI Overscan
Use SDI Overscan to enable or disable video overscan for SDI at 480i and 576i

around the edges of the image and resizes it to fit full screen. When set to disabled, a
zero percent overscan is applied to all SDI resolutions. You can also enable/disable this
feature via the RS-232 and RS-485 protocols.
From the Technician Menu, press the ▼ button to select Mode MenuSDI Overscan
and then press ENTER.

signals at 480i and 576i resolutions. The setting percentages are 0.0%, 2.5% (default),
3.0%, 5.0%, and 10.0%. The overscanned image will automatically update when you
switch between percentage values. You do not have to cycle power for the change to
take effect. You can also change the overscan value via the RS-232 and
RS-485 protocols.
