S
T
f
eatures automatic and manual EDID
ad
j
ustments to maximize compatibilit
y
o
f
all attached devices. First, it is
n
ecessar
y
to understand EDID and what it is used
f
or.
EDID. What is it and what is it used for
?
U
nder normal circumstances, source devices will require in
f
ormation about a
c
onnected displa
y
device to assess what video resolutions and other
f
eatures are
c
ompatible with the output device. This required in
f
ormation is called the EDID
(
Extended Displa
y
In
f
ormation Data
)
. Almost all t
y
pes o
f
output devices
/
displa
y
s
(
computer monitor, HDTV, A
/
V receiver
)
will transmit EDID to a connected
s
ource. The source will then read this EDID
fi
le and make the necessar
y
ad
j
ustments to the output si
g
nal to ensure that onl
y
compatible resolutions
/
f
eatures are
g
enerated in the output si
g
nal.
Why is EDID so important with the GefenToolBox 4x4 Matrix with FST?
yp
The
G
e
f
enToolBox 4x4 Matrix with F
S
T uses complex technolo
gy
that routes
m
ultiple input si
g
nals to multiple outputs. The source devices will require EDID to
r
ead. Multiple devices
/
displa
y
s can be connected to the input and output ports on
the Matrix, each with their own EDID. Mana
g
ement o
f
EDID is ke
y
to ensure that
m
aximum compatibilit
y
is maintained between all devices.
What options do I have to manage the EDID in the GefenToolBox 4x4 Matrix
pg
w
ith FST
?
It is important to understand that the EDID contains much more than
j
ust
l
istin
g
s o
f
supported video resolutions and audio
f
ormats. However, resolutions
and audio
f
ormats are the two ke
y
t
y
pes o
f
in
f
ormation that a user will need to
u
nderstand how to use these EDID mana
g
ement
f
unctions.
C
ommon problems that a user ma
y
encounter while usin
g
the Matrix can be
:
1. Video ma
y
not be visible on all output devices
/
displa
y
s.
2. Audio ma
y
not be heard on all output devices
/
displa
y
s.
These s
y
mptoms usuall
y
arise
f
rom video resolution
/
audio
f
ormat
incompatibilities between the devices
/
displa
y
s connected to the outputs.
The
G
e
f
enToolBox 4x4 Matrix with F
S
T can use one o
f
two methods to acquire
and retransmit an EDID to the A
/
V source device rela

in

f
rom

n
ew EDID is created based on the hi
