3 Display calibration
The display is color critical, so it can be calibrated to meet your production requirements and recalibrated to
maintain color accuracy. The display is self-calibrated with all calibration algorithms running internally, so no
host-based software is required. The display also includes an integrated XYZ colorimeter, enabling standalone
calibration. For those that prefer to use an external instrument, a wide variety of third party measurement
instruments are supported. The display’s calibration capabilities allow for a large number of
dierent
calibration strategies, including on-demand and scheduled automated calibration.
Factory calibration
The display is color calibrated at the factory with seven factory-calibrated color presets designed to provide
default congurations for a wide variety of workows and use cases. All presets can be redened and
calibrated to meet specic requirements. The following table lists the color presets and provides information
on their conguration.

NOTE: The display ships with a factory default DCI-P3 D65 preset instead of a DCI-P3 Theatrical preset. This means it has a dierent
white point, luminance, and gamma, as compared to Theatrical defaults. This preset denition was made after consultation with major
VFX and animation studios determined that this was the more typical conguration used at an artist’s desk. However, a DCI-P3
Theatrical preset can be created using calibration commands. In addition, included in StudioCal XML samples on the optical disc
provided with the display is a DCI-P3 Theatrical calibration script, which recalibrates the factory DCI-P3 D65 preset as a DCI-P3
Theatrical preset.
Preparing for calibration
User calibration allows you to dene a color preset by specifying the calibration targets (primaries, white
point, gamma/EOTF, and peak luminance) and then calibrating the preset to the targets. User calibration can
be performed many dierent ways, including selecting options from the on-screen menus or writing a
calibration script. We will discuss these methods in detail later in this user guide. For now, let’s rst establish
some fundamentals.
Enabling the internal processor
The display ships with the internal processor disabled. This is done to reduce the display’s power
consumption to meet the energy consumption requirements for some countries, but calibration cannot be
done until the internal processor is turned on.
