If
the
DVI
or
HDMI
device
requires
the
EDID
information,
please
use
EDID
Reader/Writer
to
retrieve
and
provide
EDID
information
of
the
DVI
or
HDMI
display.
2.
All
HDMI
over
CAT5
transmission
distances
are
measured
using
Belden
1583A
CAT5e
125MHz
UTP
cable
and
ASTRODESIGN
Video
Signal
Generator
VG
‐
859C.
3.
The
transmission
length
is
largely
affected
by
the
type
of
Cat
‐
5
/
5e
/
6
cables,
the
type
of
HDMI
sources,
and
the
type
of
HDMI
display.
The
testing
result
shows
solid
UTP
cables
(usually
in
the
form
of
300m
or
1,000ft
bulk
cables)
can
transmit
a
lot
longer
signals
than
stranded
UTP
cables
(usually
in
the
form
of
fixed
length
patch
cords).
A
solid
UTP
Cat
‐
5e
cable
shows
longer
transmission
range
than
a
stranded
STP
Cat
‐
6
cable.
For
long
extension
applications,
solid
UTP/STP
cables
are
the
only
viable
choice.
4.
EIA/TIA
‐
568
‐
B
termination
(T568B)
for
Cat
‐
5e
/
6
cables
is
recommended
for
better
performance.
5.
To
reduce
the
interference
among
the
unshielded
twisted
pairs
of
wires
in
Cat
‐
5e
/
6
cables,
double
shielded
STP
cables
are
better
suited
than
unshielded
UTP
cables
to
improve
EMI
problems,
which
is
worsen
in
long
transmission.
6.
Because
the
quality
of
the
Cat
‐
5e
/
6
cables
has
the
major
effect
on
how
long
the
transmission
limit
can
achieve
and
how
good
is
the
received
picture
quality,
the
actual
transmission
range
is
subject
to
one’s
choice
of
Cat
‐
5e
/
6
cables.
For
desired
resolutions
greater
than
1080i
or
1280x1024,
a
Cat
‐
6
cable
is
recommended.
7.
If
your
HDMI
display
has
multiple
HDMI
inputs,
it
is
found
that
the
first
HDMI
input
(HDMI
input
1)
generally
can
produce
better
transmission
performance
among
all
HDMI
inputs.
