Settings
The KD-4x2CS features a library of 12 internal EDID (Extended Display Identification Data)
files, in addition to allowing any Input source to receive a copy of the EDID information of any
selected Output connected via HDMI. The default EDID setting is “04” – 1080p 2ch Digital Audio.
Changing to EDID settings may be necessary when connecting to or from an AV Receiver, or for
passing 3D content derived from a Cable or Satellite source if the default EDID has problems. They
can also speed up the switching process with cable or satellite sources.
The possible EDID settings can range from ‘01’ to ‘12’. (‘01’ is the default).

When selecting an EDID from the library (settings 01-12), your source device will “see” the KD-
4x2CS 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.
EDID settings can only be changed through the RS-232 command protocol. See the RS-232
command section below for a list of EDID commands available.
Remote Control
You may control the KD-4x2CS switching commands by
using the supplied IR Remote control. There are 2 groups
of controls, one group for each Output. Each Input can be
selected by pressing the Input numbers 1-4.
