High Definition displays with HDMI inputs use EDID (Extended Display Identification Data) to ensure that a connected Hi-Def source sends compatible audio and video signals. When displays are switched away or disconnected and then reconnected, the EDID data can be lost, resulting in an incorrect signal or complete loss of audio and/or video.
The Gefen EXT-HD-EDIDPN HDMI EDID Detective Plus has been designed specifically to address this issue by recording the display EDID date and making it available to the Hi-Def source reliably and on a continuous basis. With DDC re-clocking technology, the reliability of HDCP handshaking is improved, ensuring that the Hi-Def source always receives the correct EDID. Using the Gefen Syner-G PC software or terminal emulation via USB, the installer can also manipulate/modify the EDID data to meet installation-specific requirements and resolve system-specific compatibility issues. The HDMI EDID Detective Plus has been designed for quick and easy programming and installation.
The HDMI Detective Plus provides all the functionality of the DVI Detective N & DVI Detective Plus and adds HDCP pass-through with DDC Re-Clocking and the ability to use one of (6) pre-programmed EDID profiles and (6) user-programmable EDID banks for custom EDIDs.
The Gefen HDMI Detective Plus memorizes the EDID profile of the connected source and the display. This Virtual EDID ensures perfect video resolution and frequency timing. Activating the write-protection switch on the outside of the unit will lock the settings from to prefent any accidental over-ride.
The Gefen EXT-HD-EDIDPN provides 3 flexible EDID banks for convenient switching & setting of EDID profiles for any application. Includes (1) Local EDID bank for plug-and-play EDID detection, (6) preset EDID banks for the most common settings, and (6) configurable EDID banks for custom EDID profiles. EDID profiles can also be saved and uploaded for convenient management.
EXT-HD-EDIDPN supports High Definition HDMI (or DVI with adapter) resolutions up to 1080p Full HD, and 1920 x 1200 (WUXGA). 12-bit Deep Color, 3DTV pass-through, Lip-Sync pass-through, & CEC pass-through, and HDCP support ensure compatibility with majority of modern AV devices.
Also carries High-Fidelity 7.1-channel surround-sound audio over HDMI ('HDMI-Embedded Audio') with support for Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio.
The EXT-HD-EDIDPN supports selectable HDCP pass-through. With DDC re-clocking technology, the reliability of HDCP handshaking is improved, ensuring that the Hi-Def source always receives the correct EDID.
With a 2.7"W x 1.3"H x 1.8"D footprint and only 0.18 lbs (4.87 oz) of mass, the Gefen EXT-HD-EDIDPN takes up less space than a pack of cards and weighs about ½ of an iPhone 6. Designed with a compact form-factor, flexible EDID switching, and with quick and easy setup, the Gefen HDMI Detective Plus is the perfect portable EDID emulator for any application.

The EXT-HD-EDIDPN provides 3 flexible EDID banks for convenient switching & setting of EDID profiles for any application. The EXT-HD-EDIDPN features (1) Local EDID bank for easy EDID detection of any monitor plugged in without any software. If a suitable EDID cannot be recorded, there are (6) default preset EDID banks for the most common settings, and (6) configurable EDID banks for custom EDID recording. EDID profiles can also be saved and uploaded for convenient management using the Gefen Syner-G Software Suite or serial RS-232 terminal commands.
Before using the HDMI Detective Plus, the unit must be set with an EDID. When a source device uses the EDID stored in the HDMI Detective Plus, this is called local mode. Programming the local bank is very simple and only takes a few seconds! Simply connect the EXT-HD-EDID to the source, and the EDID data will be read by the source, providing all the necessary details of the type of signal that the display (or other sink device) can process.
NOTE: When the HDMI Detective Plus is used in local mode, HPD (Hot-Plug Detect) is always high.
The HDMI Detective Plus comes with (6) Default EDID profiles which can be copied to a bank or to the local input (HDMI In). Unlike the EDID data stored in EDID banks, these Default EDID profiles cannot be overwritten or deleted. See Default Supported EDID Profiles for a resolutions and frequencies supported. Default EDID profile manipulation can be handled through RS-232 commands or by using the Gefen Syner-G Software Suite. We will cover choosing the Default EDID profile using Gefen Syner-G method below - Please refer to the manual for recording EDID using RS-232 commands, setting up the Virtual COM Port, and all the available RS-232 commands.
Select HDMI Detective Plus from the Select Product drop-down list, at the top of the screen.
If the HDMI Detective Plus is not listed in the Select product drop-down list, click the Refresh list button and wait a few moments, then try again.
For recording EDID using RS-232 commands, setting up the Virtual COM Port, and all the available RS-232 command, please refer to the Manual.
The HDMI Detective Plus comes 6 pre-programmed EDID profiles. The details of each default EDID profile is described below.

When an EDID is recorded, the EDID data is stored on the local input (HDMI In) port. However, the HDMI Detective Plus also allows EDID data to be stored directly to any of 6 EDID banks. Each EDID can then be recalled at any time. The data in an EDID bank is saved even when the power is disconnected.
Custom EDID Features:
For Custom EDID Bank functionality, please refer to the EXT-HD-EDIDPN manual.
In order for the HDMI Detective Plus to pass HDCP content (e.g. Blu-ray, etc.), set DIP switch 4 to the OFF (up) position.
To disable HDCP pass-through, set DIP switch 4 to the ON (down) position.
