Starting Brightness Alignment - TAMUZ HCM 112 Operation Manual

Alignment of LCD Monitors

Starting Brightness Alignment

First; you have to set a value within the menu PROBE SETUP for the luminance you want to align for
as maximum, f.e. 80 cd/m
Second; select the BRIGHTNESS MENU from the AUTO COLOR MENU with the UP and DOWN keys and
starts the menu step with the PLUS (V+) key.
The BRIGHTNESS MENU shows following operational steps:
Auto Color
Probe Setup
Calibrate
Brightness
Measure
Status
x
y
Y cd/m 2
Whitepoint x
Whitepoint y
User Gamma
When the BRIGHTNESS alignment is started, and the AAC procedure runs through, all individual
alignment steps are marked in the window STATUS. The whole alignment take about 2 to 10 minutes
regarding the selected accuracy and panel conditions.
The monitor switches to an internal test generator and runs through test patterns, like BLACK, WHITE
or GREY SHADES.
Do not touch any key or send any IR remote command when AAC is running. Do not move the AAC
probe or change any other condition during the alignment.
For shorting the alignment time, it is OK to stop the procedure when a proper value is reached.
When the BRIGHTNESS alignment is done, the AAC processing stops and the monitor switches back
to normal operation mode.
Close and save this menu step by pushing the MENU key once.

Note: Any calibration should be done in a dark environment ( ~8 cd/m
the ITU, SMPTE or EBU recommendations.
Note: The BRIGHTNESS menu stops immediately when no probe is connected to the monitor
and indicates „ERROR" in the status field!
The OSD reacts slowly to commands, cause the system is searching for a probe!
Note: Under some circumstances the expected brightness value isn't available at the
measured monitor, may be to low or to high. In that case the lowest possible value will be
adjusted.
Note: LCD video monitors with a CCFL lamp backlight always reacts with a „post-roll". That
means, after setting a new value it takes some time to stabilize the backlight electronics for a
constant value. The automatic adjustment works slowly to compensate the „post-roll" effect.
The individual steps of the processing will be noted
in this window !
