Horizontal detail filter (RGB and component video inputs)

The horizontal detail filter is available only for RGB and component video inputs. The same command with a different Xn variable is available to set a combined detail filter for S-video and composite video inputs.

The X2 value specified is the output to which the filtered input is tied.

The command (D) is case sensitive.

Vertical detail filter (RGB and component video inputs)

The vertical detail filter is available only for RGB and component video inputs.

The X2 value specified is the output to which the filtered input is tied.

The command (d) is case sensitive.

Detail filter (S-video and composite video inputs)

Composite and S-video inputs support a single detail filter only, rather than separate horizontal and vertical filters. To apply a detail filter to the scaled output when the input is composite video or S-video, use the same command as the horizontal filter (D) with the X17 variable.

The X2 value specified is the output to which the filtered input is tied.
