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.
