1.3.6 Aspect Ratio

Switches the scaling method between two options:
Full Scaling – scales the X- and Y-dimensions of the input video (up or down as needed)
to the display's native resolution. (Default)
Fill To Aspect Ratio – Assuming a landscape orientation and an input video with aspect
ratio smaller than 16:9, scales the Y-dimension of the input video (up or down as
needed) to the display's Y-resolution, and scales the X-dimension to maintain the aspect
ratio (and fills the rest of the display with equal black bars on the left and right).
Note: Intellitouch and Accutouch screens may need recalibration when switching
between the options. APR screen functionality is only guaranteed at "Full Scaling".

1.3.7 Sharpness

Adjusts sharpness of video signals on a scale from -2 to 2 using 5 steps. Default: 0 (no
sharpness correction).
Note: This adjustment only available when input video does not meet monitor's native
resolution.
