6.4.1. Setting the Scaler Filter Sharpness

There are two controls that adjust the horizontal and vertical filters for the scaler.
Scaler
H Filter Cutoff
Auto
1 to 64
Scaler
V Filter Cutoff
Auto
1 to 64

6.4.2. Setting the Aspect Ratio of the Output Picture

The Aspect Ratio menu presets the user image conversion parameter to build its presets. Once selected
the user can fine adjust the picture parameters via the input and output H and V stop and stop menus.
Note: In order to save any modified state as a preset the Aspect Ratio needs to be
set to User Aspect.

With this control, you can set the cutoff frequency of the horizontal filter. Set
to either Auto or select 1 of 64 filters 1 thru 64, which are full bandwidth to
th
1/64 the bandwidth of the input signal.
With this control, you can set the cutoff frequency of the vertical filter. Set
to either Auto or select 1 of 64 filters 1 thru 64, which are full bandwidth to
th
1/64 the bandwidth of the input signal.
Full Raster - converts the full input raster to full output raster. If
the input and output aspect ratios are not equivalent there will be
aspect distortion.
User Aspect – converts the region of the input raster defined by
the Input H & V Start and Stop values to the region of the output
raster defined by the Output H & V Start and Stop values with
colored side panels.
These settings convert the input picture to 16:9 top and bottom
cuts.
These settings squeeze common stretched input video back to
4:3 side panel images on a 16:9 aspect raster.
These settings are common settings for converting 16:9 aspect
ratio images to common 4:3 formats.
