Forced HPD

The KD-HDDA1x1Pro allows modifying HPD (Hot

Plug Detection) protocol between source and display.

Modifying HPD protocol will allow overcoming HPD

handshake incompatibility between source and display.

Modifying HPD protocol may also help fix other problems

related to HDMI connectivity.

Quick Setup Guide

With the power supply disconnected, connect the source’s HDMI cable to the

Input and the Display’s HDMI cable to the Output. If a specific EDID is required,

set it now (see ‘Settings’ below for more information regarding EDID). If using the

external audio output, make the connection at this time. At this point you may

power on your display, then the KD-HDDA1X1Pro followed by the source.

changes.

HDMI HDMI

There is a library of 16 built in EDID (Extended Display Identification Data)

settings. EDID is part of the HDMI “Handshake”. The default setting, ‘0’, copies

the display’s EDID information to the internal memory of the KD-HDDA1X1Pro.

EDID settings can help negotiate the HDMI handshake in certain situations and

may be necessary when connecting to or from an AV Receiver, or for passing 3D

content from a Cable or Satellite source. They may also speed up switching when

connected to a Cable or Satellite receiver.

The possible EDID settings can range from ‘0’ to ‘9’ and ‘A’ to ‘F’.

(‘0’ is the default).

When selecting an EDID from the library, your source device will “see” the KD-

HDDA1X1Pro EDID choice instead of the display’s EDID, overriding the display’s

own EDID information. If your display is not capable of accepting the video

resolution or audio type selected, you may not see a picture or hear sound. In this

case, please choose another more compatible EDID, or use the default EDID.
