7.7.3 OUTPUT SYNC POLARITY/SYNC TYPE
• Output Horizontal and Vertical sync polarities of HDMI can be defined as Positive or Negative
• When Analog output is RGBHV, Horizontal and Vertical sync polarities can be defined as
Positive or Negative. When Analog output is YPbPr, sync type will be Bi-Level (negative) for
standard definition and Tri-Level (negative-positive) for high definition
• Sync Polarities can be defined for HDMI (Positive or Negative), RGBHV (Positive or
Negative) and RGBS (Positive or Negative). However, these Sync Polarities are only valid
when a port is set as Primary (see Section 5.3.1). For the Secondary ports, the actual
sync will usually revert to that of the Primary Port.
When the action button is pressed, the OSD turns to the following page if Analog
output is configured as RGBHV or RGBS
If the Analog output is configured as RGBS, the composite sync is simply the combined signal of
H-sync and V-sync. Please adjust the sync polarities of both H-sync and V-sync accordingly.
