Selecting a color space preset
The display provides factory calibrated color space presets, suitable for a wide variety of color-critical
workows including visual eects, animation, on-set/dailies viewing, professional photography, product
design, print/pre-press, graphic arts, and many others. Seven industry standard color spaces are provided
along with the display’s native color gamut. The following table provides information on the eight provided
standard color spaces.

NOTE: The factory DCI-P3 preset has a D65 white point, a 100 cd/m² luminance and a Power 2.4 gamma.
This diers from the DCI-P3 conguration typically found in cinema projectors (P3 white point, a 48 cd/
luminance and a Power 2.6 gamma). This is because consultation with visual eect and animation studios
determined that the D65/100/2.4 conguration was better suited to the typical artist work environment than
the cinema projector conguration.
To select a color space preset:
1. Press any Function button on the front bezel.
2. Press the Open Menu button to open the OSD.
3. Select Color settings to display the color space conguration screen.
4. Use the Up/Down buttons to navigate to the desired color space, and then press the Select button to
activate it.
Adjusting luminance
Though each preset is calibrated to a specic luminance level, the luminance can be adjusted post-calibration.
The luminance range for all calibrated color space presets can be adjusted from 48–250 cd/m

.
NOTE: Due to the way LEDs respond to voltage, the further you adjust luminance away from the calibrated
value, the less accurate the luminance value reported by the OSD will be. As you move away from the
calibrated value, the colorimetry of the white point will shift. HP recommends that you calibrate the display to
the desired working luminance. For more information about calibration, see Display calibration on page 58.
To adjust luminance:
1. Press any Function button on the front bezel.
2. Press the Open Menu button to open the OSD.
