HDMI Input Setup
After the output is configured, calibrated, and saved, you can calibrate the first input. Note that most often, no
input calibration is necessary. After calibrating the first input, you can copy that configuration to all the other
configuration memories if desired. Then calibrate other inputs. To program one of the independent input
memories, select the input, then select the configuration memory and use the menu to configure the input. For
example, if memory
A
been calibrated and a second configuration is needed, start by copying Memory
A
to
memory
B
for that input to reduce setup time for the second configuration.
HDMI Physical Input
If desired the input selection for HDMI sources can be assigned to different physical HDMI inputs. This can be
useful if a receiver or HDMI switcher is used to switch several HDMI to a single input on the Radiance. Different
settings and calibrations for several virtual HDMI inputs can be stored for the same physical HDMI input. The

HDMI Video Type
By default the HDMI input format is detected automatically. For DVI sources that do not report their format, the
input format can be selected manually. The command is:

HDMI Level
This command specifies if the HDMI inputs use video levels or PC levels. he input video level should be set to
match the expected range of your video source. A mismatch can cause the image to be too dark or bright. An
output video level mismatch can also have the same effect. The command is:

HDMI input EDID Display Information
NOTE:
Lumagen recommends using default video EDID or user-defined video EDID. This
enables the Radiance to report video EDID back to the sources even when the
display is off, and it can also improve power-up and switching speed.
EDID is information that can be read over DVI/ HDMI cables to influence how source devices deliver video, which
helps produce an optimal picture. There are 4 settings for the Lumagen EDID interface. The default setting enables
all of the display modes the Radiance supports. The
User
defined setting allows the user to individually select
which capabilities will be advertised to the source. You can scroll through the list of capabilities with the up/down
arrows and toggle advertising the feature with the left/right arrows. With the Passback setting, the Lumagen will
read the EDID from the display/AVR connected to the selected output and pass that back to the source. The

HDMI input hotplug mode
NOTE:
Do not set Hotplug to “always on” unless necessary since this eliminates the
ability of the Radiance to inform the source of a change in the EDID data.
Hotplug alerts a DVI/HDMI device to downstream EDID changes when toggled. For some devices, such as a PC, it
may be necessary to keep hotplug high at all times. The hotplug signal is part of a HDMI/DVI interface. The
Radiance provides two hotplug settings, "Normal" and "Always On". The "Normal" behavior is to toggle hotplug
signal sent back to the HDMI inputs when the EDID information needs to be updated. The will then read the EDID
and make any necessary changes. If the device connected to the Radiance output toggles the hotplug to the
Radiance then there may be some new EDID information to passback to the sources and, if hotplug is set to
"Normal", hotplug on all the inputs may be toggled to achieve this.
