Managing The Light Source; Liteloc ™ Sensor-To-Screen Calibration - Christie TruLife+ Griffyn 4K32-RGB User Manual

3. At the confirmation prompt, select Enable.
The projector reboots and the High Frame Rate button changes to Disable.
4. To change to 4K resolution, select MENU > Configuration > Input Settings > High Frame
Rate > Disable.
The projector reboots and the High Frame Rate button changes to Enable.
Issuing the (OTR <0 | 1>) serial command also toggles between the 4K and 2K resolutions.

Managing the light source

Learn how to configure brightness and color using the projector's LiteLOC feature.
Using LiteLOC, you can easily control the brightness and color of the projector. In addition, LiteLOC
can maintain these settings over time under changing environmental conditions.
LiteLOC works with a sensor-to-screen calibration that ultimately allows you to input your required x,
y chromaticity coordinate in the user interface and control the brightness of the projector with a single
slider.
LiteLOC's ability to hold required color and brightness depends on your environmental conditions.
Conditions resulting in a low dew point such as low ambient temperature and low humidity result in
higher maximum brightness. On the other hand, conditions resulting in a high dew point such as high
ambient temperature and high ambient humidity result in lower maximum brightness. When the
environmental conditions exceed the projector's ability to maintain the required brightness, it
automatically dims as necessary to maintain your required color point on the screen. In this case, the
projector also issues a warning. If the environmental conditions become better, the projector recovers
your original required brightness.
LiteLOC ™ sensor-to-screen calibration
The LiteLOC sensor-to-screen calibration is performed in the factory under specific setup conditions
which include the type of lens, screen, and the spectroradiometer used for measuring screen color and
brightness.
Your projector's setup conditions may not match the factory setup which may result in an error in
color accuracy. Upon first installation, check the accuracy of the color point and if unsatisfactory,
perform this calibration. Doing this calibration captures all the variables of your setup and achieves the
best results. By doing this calibration, you will not overwrite the factory calibration. Once satisfied,
some scenarios may exist in which you may need to re-do the calibration in the future.
Re-doing this calibration is required if the following is replaced:
• Color sensor board
Re-doing this calibration is optional if any of the following are replaced:
• Light engine
• Lens
• Screen
• Any other optical components in the optical path between the color sensor board and the
screen
After replacing these components, check the accuracy of the color point and if unsatisfactory, re-do
this calibration.
