OSD Agent Description
Edge Adjustment
Adjusts Picture Size and Position Controls. The four “Edge”
controls shift each edge within available limits. Note that the
maximum available shift depends on the incoming video standard
and the display panel type, and may be restricted vertically. This
provides very flexible and easy to use image size an position
control.
Moire
Corrects Moire. Choose from one of four correction tables.
Clock
Sets the total number of input pixels per line to correspond with the
input source, and will normally require adjustment for unusual
signals.
Phase
Adjusts the internal clock to sample each pixel as near as possible
to the centre. Phase will normally require adjustment for unusual
types of signal.
Aspect Ratio
Selects the displayed aspect ratio where the signal input is at
variance with the display panel’s natural aspect ratio. The format
may be adjusted to either “Letter Box” or “Overscan”. “Letter Box”
effectively adjusts the height of the displayed image and “Overscan”
effectively adjusted the width to achieve the desired 4:3 aspect
ratio.
Input Select: Configures the preferred input selections.
(If a facility is not fitted, it will be displayed but not selectable.)

adjusted for the desired color balance and to minimize noise on low
intensity colors and greys. Color tints can be added as required.
