E
DID: What is it and what is it used for?
U
nder normal circumstances, an source device
(
di
g
ital and analo
g)
will require
in
f
ormation about a connected device
/
displa
y
to assess what resolutions
and
f
eatures are available. The source can then cater its output to send
onl
y
resolutions and
f
eatures that are compatible with the attached device
/
displa
y
. This in
f
ormation is called EDID
(
Extended Displa
y
In
f
ormation Data
)
and a source device can onl
y
accept and read one EDID
f
rom a connected
device
/
displa
y
. Likewise, the source an onl
y
output one resolution
f
or use b
y
a
c
onnected device
/
displa
y
.
Wh
y
is EDID so important with the 1:8 DVI Distribution Amplifier?
Th
e
1:8 DVI Distribution Amplifier
is complex piece of technology that replicates
r
and switches between multiple inputs and outputs. Each connected source
device will require one EDID to read. EDID mana
g
ement is care
f
ull
y
handled b
y
1:8 DVI Distribution Amplifier
to provide a single EDID for each source to read.
r
What options do I have to mana
g
e the EDID in the 1:8 DVI Distribution
Am
p
lifier?
First, it is important to note that each source device can onl
y
output one video
/
audio si
g
nal t
y
pe. This includes resolutions and timin
g
s. When multiple devices
/
displa
y
s are used, such as with the
1:8 DVI Distribution Amplifier
, it is important
r
to use devices
/
displa
y
s that have similar or compatible resolutions
/f
eatures. This
will ensure that the sin
g
le video
/
audio si
g
nal produced b
y
the source device is
accepted b
y
all o
f
the connected output devices
/
displa
y
s.
The user has the option, throu
g
h a combination o
f
DIP switch settin
g
s within the
1:8 DVI Distribution Amplifier
, to choose how the unit will manage the EDID from
r
m
ultiple HDMI devices
/
displa
y
s. There
f
ore the user has some control over the
r
esolutions
/f
eatures that the source devices will output. The
1
:
8
DVI Distribution
Amplifier
has a multiple EDID management modes that will control how the EDID
r
in
f
ormation
f
rom multiple devices
/
displa
y
s are combined, i
g
nored, and routed.
How do I chan
g
e EDID modes in the 1:8 DVI Distribution Amplifier?
There is an bank o
f
8
DIP switches located on the main-baord inside o
f
the
1
:8 DVI Distribution Ampli
fi
er
.
DIP switches 1, 2, and 5 are used in di
ff
erent
c
ombinations to mana
g
e the EDID modes.
To access these DIP switches it will be required to open the unit. To do this,
