Detail Enhancement
The detail control sets the amount of enhancement applied to the picture. The adjustable
detail enhancement feature allows image sharpening. Fine edge detail processing
additionally ensures that the picture remains clear and sharp without creating unpleasant
jagged edges.
Video gains and offsets (Gain)
The RGB gain and dc offset controls allow adjustment of the image brightness, contrast
and colour.
From the Gain top menu press ENTER then SCROLL to access the video gain and offset
controls.

Picture Crop (Crop)
From the Crop top menu press ENTER then SCROLL to access the picture crop options
along with the closed caption and wide screen signalling controls. These controls act to
crop the input video so their action will be affected by the aspect ratio selection. Up to 31
lines of vertical crop both top and bottom are available and up to 31 pixels horizontally
both left and right.
When an aspect ratio is selected which results in a vertical shortening of the picture any
NTSC closed caption information would become visible and any horizontal scaling would
corrupt this information. The closed caption control if selected will blank lines 20 and 21
of the input video to remove this information from the visible picture and reinsert the
information in lines 20-21 of the output video so preserving its integrity.
PAL wide screen signalling on line 23 may also be selected for blanking.
