HDMI Input Setup
After the output is configured, calibrated, and saved, you can calibrate the first input. Note, generally no input
calibration is needed.
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. Hint: If memory A has 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 Virtual to Physical Input Mapping
If desired the input selection for HDMI sources can be assigned to different physical HDMI inputs. This “Virtual
Input” feature can be useful if a receiver or HDMI switcher is used to switch several HDMI sources 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 command is:
MENU → Input → HDMI Setup → Physical In → (1, 2, 3, 4, 5, 6, 7, 8)
HDMI Video Type
By default the HDMI input format is detected automatically. For DVI sources, the Auto mode selects RGB format.
For sources that do not report their format correct, the input format can be selected manually. The command is:
MENU → Input → HDMI Setup → Type→ (Auto, RGB, YCbCr 422, YCbCr 444, RGB-fixup601)
HDMI Level
This command specifies if RGB HDMI inputs use video levels or PC levels. The 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 only applicable for the RGB input
format. The command is:
MENU → Input → HDMI Setup → Level → (Video, PC)
Video EDID Display Information for HDMI inputs
NOTE:
Lumagen recommends using the default video EDID or a user-defined video EDID. This
enables the Radiance to report video EDID back to the sources even w hen the
display is off, and it can also improve pow er-up and sw itching 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 Radiance will
read the EDID from the display/AVR connected to the selected output and pass that back to the source. The
command is:
MENU→ Input→ HDMI Setup→ Video EDID→ (Default, User defined, Passback Out2,
Passback Out1)
HDMI Input Hotplug Mode
NOTE:
Do not set Hotplug to “alw ays on” unless necessary since this eliminates the
ability of the Radiance to inform the source of a change in the EDID data.
The Hotplug signal is part of a HDMI/DVI interface. Hotplug alerts a DVI/HDMI source 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
Radiance provides two Hotplug settings, "Normal" and "Always On". The "Normal" behavior is to toggle the
Hotplug signal sent back to the HDMI source when the EDID information needs to be updated. The source 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 pass back to the sources and, if
Hotplug is set to "Normal", Hotplug on all Radiance inputs would be toggled to inform the sources of the change.
