Introduction
The
LDE - 050 D VI Repe a ter
is a device that can help stabilize and
enhance the digital video signals carried over the DVI cable for long e r
distance. The
DVI inte rfa c e te c h n ol o g y
uses pure ly digital
transmission to eliminate the dist ortion due to digi tal/analog conversion
seen in the co nv entional HDB inter face. Ho we ver, digital signals can
also suffer from degradation a nd att enuation due to cabling distance
factors. This DVI Repeat e r is the solution to exte nd your DVI ca bling
for longer dista nce yet retains be st digital video qualit y. This DVI signal
enhancement d evice offers a pu r ely digital
DVI -D Single Link
si gnal
su pport to offer genuine digital v ideo quality for yo ur Flat Panel
Displa y s over longer cable exte nsi on over 15 m eters*. Using this DVI
Repeate r, you can enj oy digital ly clean and clear images over longer

Troubleshooting
No screen shown on the DVI Display while connected to the DVI
repeater
Please go through the following troubleshooting steps to verify the cause of
the problem:
1. Check Power LED to see if it is lit. If the Power LED is not lit, it means
your DVI Repeater is not powered on at all. If that is the case, check
whether you have connected the external power adapter properly to it, or
whether there’s any failure from the power source.
2. Check whether you have connected the DVI Repeater correctly.
The correct connection to be made is to connect the DVI Input port to your
computer, using a good quality DVI video cable, and to connect the DVI
Output port to the DVI Monitor’s own video cable. If you connected it in the
wrong way, try to reconnect it correctly.
3. Check whether the video signal source output from the DVI
port of your computer is OK. You can check it by connecting it directly
to your monitor to see if the monitor can display properly. If your monitor
cannot display properly even when directly connected to the computer, it
means the video output is not valid on the computer. If that is the case, try
to reboot the computer still connected with the monitor and see if the video
source output resumes. If not, then your video source output is the cause.
4. If you have checked through 1, 2 and 3 and found no problem with
power or connection, then you should try to disconnect all cables from
your DVI Repeater. Wait for a few seconds and first connect the
external power adapter to it, then connect the computer and Monitor to
the DVI Repeater. The reason for doing so is to reset the DVI Repeater
system itself. The DVI Repeater might not be properly powered on if you
connect it to the computer before connecting it to the external power
adapter, especially when using a long cable (which will diminish power
coming from computer and making the DVI Repeater non-functional). If
that is the case, a system reset on the DVI Repeater is therefore required.
If you have tried all these steps and still the cause of problem remains
unclear, try to contact your local dealer for technical support.
The DVI video screen is dispersed with dusty speckles
The dusty speckles on the monitor might be caused by a DVI Repeater
system not properly powered on. For troubleshooting, you should
perform a repeater system reset : (1) try to disconnect all cables from
your DVI Repeater. (2) Wait for a few seconds and first connect the external
power adapter to it, (3) then connect the computer and Monitor to the DVI
Repeater. The reason for doing so is to reset the DVI Repeater system itself.
The DVI Repeater might not be properly powered on if you do not first
connect it to the external power adapter, especially when using a long cable
video cable.

(which, if with no external power source, will diminish power coming from
computer and making the DVI Repeater non-functional). If that is the case,
a system reset on the DVI Repeater is therefore required. Also if you are
using long cable or the cable quality is not good, it is more likely that you’ll
see speckles on the screen.
The video screen is OK with short cable (within 5 meters) but no
screen with longer cable (within 5 ~ 15 meters)
First, you should try to perform a repeater system reset (see previous point)
to see if it is due to improper connection sequence. After a repeater system
reset, if you still see no screen, then it might be due to poor quality of your
longer DVI video cable. Then replace the longer video cable with a good
quality one, such as the CAB-2035 we provide.
