Adjusting Luminance

Selecting a Color Space Preset

The Z27x provides factory calibrated color space presets, suitable for a wide variety of color-critical workflows including visual effects, animation, on-set/dailies viewing, professional photography, product design, print/pre-press, graphic arts, and many others. Five industry standard color spaces are provided along with two different ways to access the display’s native color gamut. The following table provides information on the five provided standard color spaces.

Preset Name	Red Primary	Green Primary	Blue Primary	White Point	Gamma	Luminance
	(u’v’)	(u’v’)	(u’v’)

sRGB	0.451, 0.523	0.125, 0.563	0.175, 0.158	D65	sRGB	250 cd/m2
AdobeRGB	0.451, 0.523	0.076, 0.576	0.175, 0.158	D65	2.2	250 cd/m2
BT.709	0.451, 0.523	0.125, 0.563	0.175, 0.158	D65	2.4	100 cd/m2
BT.601	0.432, 0.525	0.130, 0.562	0.175, 0.158	D65	2.4	100 cd/m2
BT.2020	0.557, 0.516	0.056, 0.587	0.159, 0.126	D65	2.4	100 cd/m2
DCI P3	0.496, 0.526	0.099, 0.578	0.175, 0.158	P3	2.6	48 cd/m2

In addition, the Native preset provides access to the display’s native color gamut. This preset has also been calibrated to have a D65 white point and a 2.2 gamma.

To select a color space preset:

1.Press any button on the front bezel.

2.Press the bottom Open Menu button to open the OSD.

3.Select Color Space to display the color space configuration screen.

4.Use the Up/Down buttons to navigate to the desired color space then press the Select button to activate it.

Though each preset is calibrated to a specific 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/m2. The Native preset can be adjusted from 0–100% of maximum display luminance.

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. HP recommends that you calibrate your monitor to the desired working luminance.
