7.12.3. Filter Settings

7.12.3.1. Scaler Filter Sharpness
There are two controls that adjust the horizontal and vertical filters for the scaler. Effectively, these
controls manage the cut-off frequency for the Horizontal and Vertical filters.
The smaller the value, the narrower the corresponding filter bandwidth and the less aliasing passed
through to the output. The larger the value, the wider the corresponding filter bandwidth.
The H Filter Cutoff controls the Horizontal filter bandwidth. It also has several unique filters that have
specific enhancement profiles.
Auto
Enhance HF 1 db
Enhance HF 2 dB
Mid Band Boost 1 dB
Mid Band Boost 2 dB
Levels 5....64
The V Filter Cutoff controls the Vertical filter bandwidth.
Auto
Levels 1....64
