DARK TIME and OUTPUT DELAY NOTES:

The "dark time" between incoming L/R frames provides a brief interval of non-image
time—in microseconds (µ)—for your switching device (such as shutters in glasses)
to complete its switch. Ideally, when this interval is properly set and exactly suits the
speed of your device, neither eye sees image data intended for the other eye. This
helps to prevent color artifacts and ghosting while ensuring that each eye sees all
intended data.
NOTE: Because the Dark Time interval essentially increases frame rate, increasing
this setting beyond its range for the current frame rate factor will cause image break-
up. 2048 x 1080 displays may be cropped. Likewise, a setting less than the minimum
is not supported, and will simply revert to the minimum interval.
The Output Delay setting shifts the 3D sync in relation to the Dark Time interval,
starting each frame slightly earlier (–) or later (+). Adjust only as necessary—too
much offset can cause "bleed-through" where each eye sees some data that is
intended for the other.
CUSTOM / LAMP MENU:

level for the lamp.

The TPC Advanced menu consists of five different submenus—Preferences, Lamp,
Lamp History, Test Patterns and User—that enable installers, administrators and
advanced users to define numerous system operating parameters, load and/or display
test patterns, work with lamp settings, and set up users and their TPC access rights.
ADVANCED / PREFERENCES MENU:
access to all test patterns as well as certain system parameters. See Table 3.7 for a

When enabled, LiteLOC setting is applied to the specified channel.
When disabled, all channels will use the global LiteLOC setting.
Maintains a chosen light level at the screen over time – the lamp
ballast will gradually increase power to the lamp as necessary,
until it reaches the maximum level possible for the installd lamp.
To disable LiteLOC temporarily or permanently, clear the LiteLOC
"enable" checkbox or adjust Lamp Power directly.
Indicates what percentage of power (appropriate for the
installed lamp) to supply to the lamp, automatically overriding
any LiteLOC setting that may be in effect. This causes the bar
graph to rise or fall, but the LiteLOC line and "set" value will not
change unless "Set" is pressed (defining a new LiteLOC
setting).
With the desired light output measured at the screen, press
"set" to automatically enable LiteLOC. The current brightness
level will be maintained as long as possible. NOTE: Arbitrary
units shown here, not footlamberts or lumens.
