Chapter 8, 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
scale the output, 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.
¦NoteThis utility is best viewed at a display resolution of 1280×800 or higher.
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 79). You can later choose to enable
or disable the loaded calibration settings (see “Enabling and disabling the Matrox
HDMI calibration settings” on page 80).
¦NoteAn administrator username and password is required to calibrate your
HDMI monitor.
1 Ensure that your HDMI monitor is connected to MXO2’s HDMI output, turn
the HDMI monitor on, and allow it to warm up for about 20 or 30 minutes.
2 From the Apple menu, click System Preferences, and then click the
Matrox Utilities icon.
