EDID. What is it, and what is it used for?
,
U
nder normal circumstances, a computer source device
(
di
g
ital or analo
g)
will
r
equire in
f
ormation about a connected device
/
displa
y
to assess what resolutions
and
f
eatures
(
capabilities
)
are possible. The source device can then cater its
output to create resolutions and
/
or
f
eatures that are compatible with the attached
device
/
displa
y
. This capabilit
y
in
f
ormation is called EDID
(
Extended Displa
y
Identi
fi
cation Data
)
. A source device can onl
y
accept and read one EDID data
s
tructure
/
record
f
rom a connected source device
/
displa
y
. Likewise, the source
device can output onl
y
one video resolution to a connected device
/
displa
y
.
The importance of EDID with regards to the 8x1 DVI KVM DL Switcher
pg
The 8x1 DVI KVM DL
S
witcher handles multiple sources
/
inputs. Each connected
s
ource device must correctl
y
read one EDID data structure in order to address its
displa
y
device correctl
y
. EDID mana
g
ement is care
f
ull
y
handled b
y
the
S
witcher
to insure that EDID is recorded and retransmitted to sources properl
y
at all times,
otherwise displa
y
o
f
input sources mi
g
ht not happen correctl
y
(
or at all
)
.
Managing EDID with the 8x1 DVI KVM DL Switcher
gg
The 8x1 DVI KVM DL
S
witcher has 2 modes
f
or routin
g
EDID
:
1. The de
f
ault mode is the L
OC
AL mode which will store the EDID o
f
a source
device
(
one
f
or each input
)
into the 8x1 DVI KVM DL
S
witcher. The EDID
s
tored in each L
OC
AL location can be
f
rom a local displa
y
device or
f
rom
a remote source over the R
S
-232 serial communications port. The 8x1 DVI
KVM DL
S
witcher also includes a built-in EDID memor
y
bank which can
s
tore up to 7 separate EDID data structures which can then be loaded to
e
ach o
f
the L
OC
AL EDID locations.
2. The second mode is the D
S
(
Down
S
tream
)
mode which
f
unctions as a
s
imple EDID pass-throu
g
h. In this mode, the displa
y
device connected to the
8
x1 DVI KVM DL
S
witcher will pass its EDID directl
y
to whichever DVI input
s
ource is currentl
y
selected. HDCP is supported in this mode only.
N
