How It Works
The 1:2 V

C
video source with a V

A
(
male to

emale
)
c
able
f
rom the computer’s V
G
A
g
raphics card port to the V
G
A Hub’s input con-
nec
t
o
r.
There are two V
G
A outputs on the 1:2 V
G
A Hub. V
G
A output one
(
Monitor 1
)
is the primar
y
connection, which queries the primar
y
sispla
y
attached to it and
determines the possible video resolutions, timin
g
s and
f
requencies that can be
u
sed to create a picture. This in
f
ormation is called EDID
(
Extended Displa
y
Identi
fi
cation Data
)
.
V
G
A output two is connected to the second
(S
econdar
y)
displa
y
and creates an
ima
g
e b
y
f
ollowin

the EDID settin
g
s obtained
f
rom the

rst

;
there
f
ore, both displa
y
s should be capable o
f
the same resolutions and re
f
resh
r
ates in order to displa
y
an identical picture. For more in
