■ Safe Action area and Safe Title area graticules – When enabled, Safe
Action and Safe Title area graticules are displayed to show the safe areas of
the picture to aid in monitoring for incorrect placement of graphics, logos,
and other branding elements to ensure that they do not obscure text of
essential action. The graticule areas indicate the maximum image area within
which all significant action or titles should be contained.
The graticule sizes are defined by the selected standard (SMPTE, BBC, or
ARIB B-4) and the selected aspect ratio (Auto, 4x3, 14x9, 16x9, or Custom).
Custom settings will override the aspect ratio of the monitored input. You
can display up to four safe area graticules (two Safe Action and two Safe
Title) at a time. You can specify up to two custom safe area graticules.

image.

CONFIG > Graticules & Readouts menu, the cursor highlights the selected
