Chapter 7, Calibrating Your HDMI Monitor for Video
Overview
The Matrox HDMI Calibration Utility is a unique tool designed to calibrate your
RGB HDMI monitor or television so that it performs like a traditional broadcast
video monitor. This utility provides a wizard that walks you through the
calibration process using specially designed patterns to effectively identify and
compensate for the processing errors that may be present in your HDMI monitor.
The Matrox HDMI Calibration Utility calibrates your monitor’s black and white
levels, white point, gamma response, and hue and chroma.
This utility is optimized for calibrating HDMI LCD/LED monitors or televisions
that support 1:1 pixel mapping, which allows you to view the output on your
HDMI monitor at its exact resolution without any scaling. Although instructions
are provided for calibrating plasma HDMI monitors, and HDMI monitors that do
not support 1:1 pixel mapping, a blue-only filter will be required for the color
calibration (hue and chroma). Some HDMI monitors feature a built-in blue-only
mode that you can use for color calibration. If your HDMI monitor does not have
a built-in blue-only mode, you can use a proper third-party blue-only filter (for
example, a blue gel filter, or blue-only calibration glasses) that completely blocks
out all colors except for blue. Because some blue-only filters do not block out
colors effectively, the Matrox HDMI Calibration Utility includes a blue-only
filter test that you can use to determine if your blue-only filter is adequate for
color calibration.
¦ Note To ensure that the Matrox HDMI Calibration Utility displays correctly,
your computer screen’s resolution must be 1280 × 800 or higher, and the
Windows DPI scaling option for text must be set to the default size. For details on
how to change your screen resolution and DPI scaling setting for text, see your
Windows documentation.
Calibrating your HDMI monitor
The Matrox HDMI Calibration Utility provides on-screen instructions to
calibrate your HDMI monitor. At the end of the calibration process, you must
save your calibration settings to a file. Once saved, the calibration settings are
automatically loaded as your system’s current calibration settings. If you’re
calibrating more than one HDMI monitor, you can calibrate and save settings for
each monitor and load the corresponding settings at any time (see
“Loading
Matrox HDMI calibration settings” on page 50 ). You can later choose to enable
or disable the loaded calibration settings (see “Enabling and disabling the Matrox
HDMI calibration settings” on page 50 ).
The Matrox HDMI Calibration Utility uses the Matrox WYSIWYG Control
Panel to display the specially designed patterns that are required to calibrate your
HDMI monitor. Therefore, you’ll need to configure your Matrox WYSIWYG
output settings as explained in this section. For more information about using the
