SYNC

Sync format

3, 4, or 5 wires

This command applies to 
analog RGB inputs only.  

In 3 wire sync systems the H & 
V sync signals are combined 
with the Green signal.

In 4 wire sync systems the 
H&V sync signals are 
combined and transmitted on a 
dedicated wire.

5 wire systems the H & V 
signals are transmitted on 
separate dedicated wires.

HPOL

Horizontal sync polarity

1 or 0

The value “1” represents 
positive sync polarity and the 
value “0” represents negative 
sync polarity. Typically the 
horizontal and vertical sync 
have the same polarity.  Note 
that three wire sync is always 
negative polarity.

VPOL

Vertical sync polarity

1 or 0

The value “1” represents 
positive sync polarity and the 
value “0” represents negative 
sync polarity.  Note that three 
wire sync is always negative 
polarity.

IL

Interlaced/Noninterlaced

1 or 0

The value “1” represents 
interlaced scan and “0” 
represents non-interlaced 
(progressive) scan.  Note that 
video signals are typically 
interlaced, and graphics signals 
are typically non-interlaced.
