EDID Control
EDID authentication is provided from the KD-X611ProK Tx unit to the connected
input / source device. The EDID file (AKA “handshake”) is selected using the EDID
Control rotary on the Tx unit and provides a list of compatible video and audio
formats as well as digital data, informing the source device what it should output.
Most sources will comply with a new EDID file without a power-cycle, but each
source may behave differently. Adjustments

Forced Hot Plug Detection (HPD)
Hot Plug Detection (HPD) may be forced on the Tx Rx unit in order to provide
connected devices with necessary voltage to inform the device that a partner
(display) is connected and active. If the Control rotary is set to any HPD Bypass
setting, HPD signals from the output to the input device will pass as normal. In
cases of many layers of connectivity, HPD may be lost leading to no signal at the
display. In those cases, fix the Control rotary to any Forced HPD setting.
