INTRODUCTION
lose the ability to display the image properly
How It Works
You simply program the DVI Detective Plus for the display that you will use, by
performing a programming step while having the device connected to the display
and a power adapter. Next, you put it into place on the video output of your video
source and restart your equipment. When all sources and displays are powered on,
seamless functioning of video source and display equipment will commence.
External buttons make EDID programming and settings operations a breeze -formerly, some operations could require opening the unit.
Computers and HDTV video source devices can sometimes lose the EDID -basically the electronic identifi cation of a display which lists its possible resolutions
and frequencies. When displays are switched away or disconnected and then
reconnected, the EDID can be lost and the computer or HD video source device can
lose the ability to display the image properly

CONNECTING AND OPERATING THE DVI DETECTIVE PLUS
display to ensure that an EDID is being transmitted.
Plug the supplied 5V DC power supply into the DVI Detective Plus. The power 3.
LED should be glowing either solid RED (an EDID is not programmed) or solid
GREEN (an EDID is properly programmed).
Once you are ready to program the EDID, press and hold the Program button 4.
on the front panel of the DVI Detective Plus until the unit’s LED begins to
rapidly fl ash green. Once the recording sequence is initiated, release the
button and wait until the LED glows a solid green color. A successful EDID
programming sequence is indicated with a green LED while an unsuccessful
EDID record is indicated with a red LED.
NOTE: If the unit does not initiate the recording sequence, indicated by a fl ashing
green LED, please unplug the display and 5V DC power supply from the unit and
repeat steps 2 and 3. If a solid red LED is indicated after several unsuccessful
recording attempts, it is possible that the EDID from the display being recorded is
bad. Please refer to the USING A PRE-PROGRAMMED EDID section on page 6
and 7 for instructions on how to use one of the built in EDID’s.
Before proceeding, please ensure that the write protect switch is in the E (write 1.
enabled) position and all SETTING DIP SWITCHES are in the OFF (down)
position Please see the diagram on the page 8.
Connect the display to the DVI Out port on the DVI Detective Plus. Turn on the 2.
display to ensure that an EDID is being transmitted.
Plug the supplied 5V DC power supply into the DVI Detective Plus. The power 3.

6. If HDCP is required by the source, the display must also be HDCP compliant
and DIP SWITCH 4 will have to be enabled for HDCP pass through to function.
Please refer to your source and display manuals for HDCP compatibility and
enable DIP SWITCH 4 appropriately.
7. The source should be powered off when connecting it to the DVI In port on the
DVI Detective Plus.
8. Power on the source.
Note: If using a PC, restart your computer only after you’ve made all the
connections.
5. Once a successful EDID record is complete, remove the 5V DC power supply
from the DVI Detective Plus. At this time, it is recommended that you write
protect the DVI Detective Plus to prevent an accidental overwrite. Please see
page 9 for instructions on this procedure.
6. If HDCP is required by the source, the display must also be HDCP compliant
and DIP SWITCH 4 will have to be enabled for HDCP pass through to function.
Please refer to your source and display manuals for HDCP compatibility and

The DVI Detective Plus includes 5 built-in manually-selectable generic EDIDs
(display identities) for forcing several standard home theater setups with multichannel audio and standard HDTV resolutions. This functionality is vital when
equipment reaches a state of indeterminate function and will not respond to signals
or controls properly, and a certain resolution size with specifi c audio must be forced
upon all connected equipment. Below is a table with the listed resolutions, refresh
rates, and audio channels for each pre-programmed EDID.

WRITE PROTECTING THE DVI DETECTIVE
Once the DVI Detective is programmed and working, you can write protect the unit
to prevent an accidental overwrite. This is done by simply moving the write protect
switch to the D (write disabled) position. By default, the unit is shipped in the E
(write enabled) position. This is done so that the unit is ready to be programmed
right out of the box. Whenever the unit is going to be programmed, make sure that
the switch is in the “E” position, otherwise the procedure will not work. The power
LED will fl ash in alternating green and red colors to indicate that the DVI Detective
Plus is currently write protected.
