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.

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.
