2 Product Outline
The IDK DDC-03UHD is a 4K@60 and HDCP 2.2 supported EDID emulator. The emulation feature enables a
source device to output video and audio that are optimal for the monitor’s functions and performance when
the source device, such as PC and Blu-ray player, is connected to monitor.
The input cable equalizer and CDR (Clock Data Recovery) that reclocks input signals degraded by HDMI
cables.

1080p@60: 65.6 to 98.4 ft. (20 to 30 m)

[Fig. 2.1] DDC-03UHD diagram
Normally, the source device acquires EDID of the connected monitor to output optimal video and audio, but in
some cases, appropriate EDID cannot be acquired. For example, if the source device has problems for
acquiring the monitor’s EDID or if the characteristics of the source device and monitor are not the same, the
problem occurs. In such cases, the DDC-03UHD sets EDID in place of the monitor to avoid problems.
For PCs, the timing of acquiring EDID differs between Desktop PC and laptop PC.
- A desktop PC is connected to a monitor without the DDC-03UHD: The desktop PC acquires EDID at the
time of startup or connection and then outputs video and audio.
- A laptop PC is connected to an external monitor: The laptop PC acquires EDID at the time of output setting
of the external monitor and then outputs video and audio.
The DDC-03UHD is connected between a source device and monitor: The source device acquires EDID and
then outputs video and audio when the DDC-03UHD’s EDID setting is changed.
Built-in EDID, copied EDID, and external EDID can be set. See “7 Basic Operation”for details.

As explained in the second chapter, the DDC-03UHD includes EDID emulation function as an extender.
For video, 4K@60Hz (4:4:4) and HDCP 2.2, HDR, 3D, and x.v.Color are supported. For audio, at the time of
built-in EDID selection, it is possible for audio not to be output from the source device by disabling the audio
information of the selected EDID.

For digital systems, some problems, such as an HDCP authentication error, can often be recovered by
physically disconnecting and reconnecting the digital cables. The Connection Reset feature will fix these
problems automatically without the need to physically plug and unplug the cables. The DDC-03UHD
passes through the Connection Reset function. If other devices are connected between the DDC-03UHD
and the sink device, this feature may be invalid.
