The main issue is that TV EDID is sometimes misunderstood or misinterpreted by the AVR in between the HDMI source and AVR. As a result the AVR reports wrong EDID data to the source and nothing works.

One way Key Digital has found to eliminate or reduce the issues when using AVR’s, is to insert a KD-HDDA1x2 distribution amplifier between the AVR and the display. Once KD-HDDA1x2 (or any other of our DA) is inserted, it buffers this misunderstanding and provides ‘perfect’ default EDID to the system and both the AVR and the source are happy and signal goes through.

The Phantom Series KD-HDDA1x2 distribution amplifier, using its ‘EDID Control’ technology, features an internal library of 4 Default HDMI Handshakes and will act as a buffer for the handshake between the receiver and the display. Your source will see the receiver and its connected DA (set to one of the default EDID’s) and negotiate the handshake with the DA. The DA will then send its signal on to the display reliably and as an added benefit, less lag time between switching.

Once a legal (HDCP) source(s) and legal (HDCP) displays are connected to Key Digital’s HDMI product(s) and a key has been established, Key Digital will authenticate all the topology of the connected products without a problem between the source and the display.
