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”.
