to understand EDID and what it is used

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

ormation Data
)
. Almost all t
y
pes o
f
output devices

displa
y
s
(
computer monitor, HDTV, A

will transmit EDID to a connected

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.

It is important to understand that the EDID contains much more than

ormats. However, resolutions
and audio
