optimally adjusted. We have included one test pattern designed specifically for this application. On some
displays, these settings, may not be available unless you get into the service menu. We recommend that
you hire an ISF-certified technician to make these adjustments if you do not feel comfortable getting into
the service menu.
A Typical Calibration Session:
Display calibration is a process that requires some level of expertise. Companies like
AVPro Alliance
offer
Imaging Science Foundation [ISF] certification classes using CalMAN, and
LionAV
offers THX calibration
classes using ChromaPure; both run over a few days to train an installer in the art and science of
calibration. While there are some excellent tools that help automate the process, a thorough
understanding of the relative level of importance of each adjustment and some means to objectively
measure the result with a calibrated meter are required to achieve an optimum result. Nevertheless, many
adjustments can also be made by eye by using a specially designed pattern. To this end, AVLab TPG has
both visual patterns for quick adjustments as well as computer controlled patterns for use with software
control.
**Note that this is only an overview of the process – more detail can be found in a great overview by

**Kal at CurtPalme.com also has an excellent step by step process using the ChromaPure system that
can be found
here
: Chromapure software can be found on the included USB flash drive.
**What Color Calibration Software to use? While there are a number of choices, there are three that stand
out: CalMAN by Spectracal (trial version on disk), ChromaPure (trial version on disk), and HCFR – a
free/open source package that can be found
here
.
A typical calibration normally involves the following steps but many other checks and adjustments can
also be performed. This example process is based on the ISF workflow using CalMAN 5.3 software.
