positive or negative H and V sync by rotating either the Adjust horizontal ( ) or
Adjust vertical ( ) knob.
If the previous output signal was specified as RGsB or YUV, this submenu
will not be displayed because this menu is only active for RGBHV.
Serration pulse removal (Serration)
When set on, serration pulses are removed from the output vertical sync pulse.
LCD, DLPs, and plasma displays must have the serration pulses removed from
the sync signal in order to display properly. Flagging or bending at the top of the
video image is a sign that the serration pulses should be removed. Using either
the Adjust horizontal (
) or Adjust vertical ( ) knob, set the serration pulse
removal to either “On” or “Off”. The default is “Off”.
Advanced Configuration
The following flowchart provides an overview of the Advanced Configuration
submenus and the options for each setting.
Detail control
This submenu allows adjustment of the image detail (sharpness) of the output
display. The adjustment ranges from 0 to 63. The default is 16.
Using either the Adjust horizontal ( ) or Adjust vertical ( ) knob, adjust the
detail while observing the output display.
Filter mode
The Filter mode, when set “On”, reduces or eliminates aliasing and the resultant
“jail bar” effect. For digital displays, set the filter “On” to reduce or eliminate
high frequency noise. For CRT output, set the filter “Off”.
Use either the Adjust horizontal ( ) or Adjust vertical ( ) knob to specify this
mode as “On” or “Off”. The default is “On”.
