2 ignites successfully, then the operational mode changes to Lamp 2 single lamp use. 3) This
option does not change the operational mode if it is set to Auto-select a single lamp.

Configuring the HDMI output options

Identify the behavior of HDMI signals.
1. To directly pass-through the HDMI input signals from the same Twin HDMI Input Card, select
HDMI Output Loop Source > Direct Loop.
The Input1 signal is looped to Output1 and the Input2 is looped to Output2.
2. To loop the main and secondary video to the outputs, regardless of which card these signal
originate from, select HDMI Output Loop Source > Main/Secondary Loop.
The main video signal is looped to Output1 and the secondary video signal is looped to
Output2.
3. To shut off the HDMI outputs completely, select HDMI Output Loop Source > Disable .

Looping video signals

In situations where a Twin HDMI Input card is being used to loop signals out to another projector,
Standby Active Loop-Through ensures that video signals continue to be looped out when the projector
enters standby power mode.
When the projector is in standby mode, and Standby Active Loop-Through is selected, limited channel
control is available—inputs can be switched, perform auto setup and some limited input settings can
be modified.

Performing diagnostics and calibration

To assist with diagnostics, configure the projector settings.
1. Select Configuration > Diagnostics & Calibration.
2. Configure the following:
• Test Pattern—Choose the desired internal test pattern to display, or select OFF to turn off
a test pattern. Alternatively, use the Test key for cycling through test patterns.
• Grey Level—Set the level of grey for displaying in the full grey field test pattern.
• Freeze Image—Enter a check mark to freeze (stop) an image on a single frame. Use this
diagnostic tool to examine in detail a still version of an incoming image that cannot be
frozen at the source. For example, in moving images it is sometimes difficult to observe
artifacts such as external de-interlacing/resizing and signal noise. Remove the check mark
to return to normal.
• Color Enabled—Select which color(s) you want to see. Use this while working with color
temperature, input levels or other special setup parameters. Colors can be enabled/
disabled by entering the corresponding function code listed on the back of the standard
remote keypad.
• Input Peak Detector—A fast method for defining individual input levels, and improving
the accuracy of input levels set by the Auto Input Level function. Enabling the Peak
Detector activates a special operating mode for detecting only pixels that are considered
black or white—all other levels are displayed as a mid-level grey. When used with a 16-
