INTRODUCTION
Congratulations on your purchase of the HDMI Detective Plus. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.
The Gefen HDMI Detective Plus
Computers and HDTV video source devices can sometimes lose the EDID --
(which is basically the electronic identi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. The HDMI
Detective Plus product allows you to switch or relocate HDTV or Computer video
displays while “tricking” the source devices into thinking that the display is still
present -- maintaining smooth video operations throughout the process.
How It Works
The Gefen HDMI Detective Plus attaches to the HDTV display’s HDMI input
connector for initial programming. Power is applied and the HDMI Detective Plus
reads and stores the attached displays EDID to the internal memory. Then the
HDMI Detective Plus is attached to your source HDMI output and it will never
lose EDID again.
The HDMI Detective Plus includes 4 built-in selectable generic EDIDs that can be
used for meeting standard home theater setups. They can be selected by moving
the dip switches between the different settings.

How to Connect the HDMI Detective Plus
1. Power-on the display (or other sink device) containing the EDID to be
recorded.
2. Use an HDMI cable to connect the sink device to the HDMI Out port on the
HDMI Detective Plus.
3. Set all four DIP switches in the OFF (up) position, as shown in the illustration
below.
4. Set the WR (Write) switch to the “E” (enable) position to allow the HDMI
Detective Plus to be programmed.
5. Connect the included 5V DC power supply to the HDMI Detective Plus. The
power LED will glow bright green if the sink device contains a valid EDID.
If the sink’s EDID is corrupt or invalid, then the power LED will glow bright
red.
6. Press and hold the Program button on the front panel of the HDMI Detective
Plus until the power indicator begins to rapidly ash bright green, then
release the Program button. The power LED will continue to ash as the
EDID is written to the HDMI Detective Plus.
A successful recording will be indicated with a solid green LED. If the
recording process was unsuccessful, the LED will glow bright red.
