| NEC Display Wall Calibrator - UsEr's GUiDE
Precautions:
The LCD display monitor screen is fragile and can be easily damaged if force is applied. Even
•
slight forces applied to the screen can cause temporary color distortions that can impact the
calibration process.
Never use suction cups to attach a color sensor to the display.
•
Always use the supplied cable or sling and counterweight to gently rest the color sensor on
•
the face of the display, or hold gently and steadily against the screen surface by hand, using the
minimum possible force.
Always try and position the color sensor in the center of the screen when taking measurements or
•
calibrating.
During the display calibration procedure, highly sensitive light measurements are made on the
•
screen using the color sensor. High ambient light levels such as direct sunlight on the screen, may
affect measurements and cause an inaccurate display calibration. Changes in ambient lighting can
alter how images on the screen are perceived.
Always store the color sensor in the holder when not in use.
•
Never touch the measurement window in the color sensor.
•
Never disconnect the color sensor while the NEC Display Wall Calibrator software is running.
•
Always allow the displays to warm up for at least 30 minutes before calibrating.
•
Note:
USB extender cables - Some models of color sensors may not work properly when using a USB
•
extender cable or when connected via a USB hub device. If you experience problems with detecting color
sensor or taking measurements with the color sensor, try connecting it directly to the host PC.
This document covers both the Mac OS and Windows versions of the software. The features and
•
functions of both versions are identical unless noted otherwise. The majority of the User Interface screen
images in this document show the Windows version, however the Mac OS version is identical unless noted
otherwise.
Analog Video Inputs - When using analog video inputs on the displays it may be necessary to
•
automatically adjust the video signal levels to compensate for variations in the video signals that may cause
color shifts between displays. See the Analog Inputs - Important Notice for more information.
