Hall Research announces Dual-Link DVI Extender w/ EDID Mgmt & USB Control

 Tustin, CA – The EMX-DVI is a single or dual link DVI extender that automatically compensates for the signal degradation caused by long video cables of up to 50 ft (15 m) on its input and can drive output cables to 40 ft (12 m). A pushbutton is used to change the mode between single and dual link TMDS signals.


The real power of the EMX-DVI is its advanced capabilities to manage EDID including its ability to “learn” and emulate EDID from any display and manage stored EDID data via its USB 2.0 port.  The Display Data Channel (DDC) can either be by-passed through the EMX-DVI, or “Emulated”, whereby the EDID is supplied from internal memory and HDCP is turned off , forcing the source to send non-content protected video without HDCP ( a useful feature for connecting PC’s to video conferencing systems  that do not support HDCP).

The EMX-DVI provides driver free USB 2.0 port connection to a PC allowing the user to acquire, save, manipulate, and write EDID tables to and from the device.

Additionally, the unit provides DVI-I bypass for analog RGBHV (or VGA) signals, so it can manage EDID for VGA sources and displays using inexpensive VGA to DVI cables or adapters. In most applications, no external power supply connection is required as the unit draws power from the video source. The EMX-DVI  is competitively list-priced at $185 and is available from stock.
