READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE HDMI TO DVI AUDIO ADAPTER
The HDMI source device needs an EDID
(
displa
y
in
f
ormation
)
to operate correctl
y
. B
y
de
f
ault, the HDMI to DVI Audio Adapter will use the EDID
f
rom the device connected
to the DVI output. I
f
the output device is a DVI t
y
pe device, audio in
f
ormation will not
be included in its EDID and audio ma
y
not be output b
y
the attached HDMI device.
To resolve this issue, the HDMI to DVI Audio Adapter carries preset EDID
’
s that
include audio

in
f
ormation in the EDID it reads to set the ri

E
DID GUID
E
EDID. What is it and what is it used for
?
U
nder normal circumstances, a 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 connected device
/
displa
y
. EDID will also
s
peci
fy
speci
fi
c audio capabilities as well, such as supported audio
f
ormats and
s
peaker allocation.
Why is EDID so important with the HDMI to DVI Audio Adapter?
yp p
The HDMI to DVI Audio Adapter will separate the video and audio stream in an
H
DMI si
g
nal to allow separate routin
g
o
f
each si
g
nal t
y
pe. The connected HDMI
s
ource device will require one EDID to read. B
y
de
f
ault, the EDID used is
f
rom the
c
onnected DVI output device. In most cases, a DVI EDID will not carr
y
the required
audio in
f
ormation that the HDMI source needs to ascertain what t
y
pe o
f
audio will
be output.
What options do I have to manage the EDID in the HDMI to DVI Audio
pg
Adapter?
p
The HDMI to DVI Audio Adapter has the abilit
y
to use preset EDID
’
s that contain
audio in
f
ormation. These EDID’s can then be used b
y
the HDMI source device to
ad
j
ust its audio output to match. These EDID modes can be set usin
g
the 4 DIP
s
witch bank located on the underside o
f
the HDMI to DVI Audio Adapter.
How do I change EDID modes in the HDMI to DVI Audio Adapter?
