HDMI/CEC
Connect an AV device to the HDMI/CEC output port on the receiver (see
G
If the device (such as a CEC-compliant display) supports CEC control, the HCR 102
can automatically turn display power on or off based on whether an active signal is
detected at the selected input.
Via PCS, this port can be configured for DVI output or for one of several HDMI formats.
You can select an HDCP output mode, and configure scaling settings to match video
resolution and rate for the display device. To facilitate setup, the receiver can output a
test pattern via this port, or it can display the on-screen menu options (see
OSD Menu System on page 28) for use during configuration.

About CEC control
Consumer Electronics Control (CEC) is an industry standard for control functions provided
by HDMI. CEC control functions are incorporated into the HC 404 and into GC software
to control other equipment. HDMI CEC implementations vary by manufacturer and by their
equipment.
Extron has tested a representative sample of equipment from other manufacturers to assure
that power on and off commands work with most devices that conform to the HDMI CEC
standard. However, CEC interoperation between the HC 404 and equipment from other
manufacturers cannot be guaranteed. Volume and audio mute commands may or may not
be supported by any given display. See the manual for the device that you want the HC 404
to control to determine the details of the HDMI CEC functions for that product, and see the
release notes for the Extron Universal Display Driver - HDMI CEC.
TIPS:
• If your display device does not support CEC commands or does not support a
full implementation of them, use one of the other control options available in the
HCR 102, such as RS-232, IR, or Ethernet control.
• Some displays must be configured to enable CEC communication.
Automatic display power control
The HCR 102 can automatically turn display power on or off based on whether an active
signal is detected at any input. The HC 404 system uses CEC driver commands sent to
the display to automatically turn display power on or off based on whether or not an active
signal is detected at any input.
• When an active signal is detected at any input, the receiver automatically sends the
CEC power-on command out the HDMI/CEC port to the display or projector.
• If no signal is detected at all inputs, the receiver sends the CEC power-off command to
the display or projector.
HC 404 systems ship with basic CEC control built into the default configuration. Basic CEC
controls in that configuration work "out of the box", but can be further customized using
Global Configurator software.
The CEC port configuration can specify whether or when to send the power-off command,
change the timeout period (from 0 to 500 seconds), and specify whether to send other CEC
commands. See the Global Configurator Help file for more detailed information on the port
and on macros.
