A Advanced Color Management Features
and Usage
The HP LP2480zx monitor provides several advanced features that make it particularly well-suited to
color-critical applications, such as professional computer graphics development, video production, and
similar uses. These include:
●
True 10-bit drivers in the LCD panel itself, and the ability to support true 10 bits/color (30 bits/pixel)
video through the DisplayPort 1.1 and HDMI 1.3 inputs.
●
An LED backlight unit (instead of the usual cold-cathode fluorescent, or CCFL type) with
independent control of the red, green, and blue channels. This permits white point control using
the backlight, and a very wide range of white level (peak luminance) settings.
●
The LED backlight, coupled with specially-selected color filters in the LCD, provides a very wide
gamut (133% of the 1953 NTSC gamut area, as expressed in the CIE 1976 u′v′ space) for this
monitor. As this gamut encloses a number of standard output device gamuts, such as Adobe RGB
and sRGB/Rec. 709, this enables accurate emulation of these standards by means of gamut-
adaptation capabilities built into the monitor.
NOTE: In the earlier 1931 CIE xy space, the gamut area of the LP2480zx is 110% that of the
1953 NTSC gamut.
●
The monitor “front-end” electronics provides support for the gamut adaptation mentioned above,
including numerous factory-adjusted color space presets, which permit the user to quickly set up
the monitor to accurately emulate these standard output device specifications. The factory-
calibrated presets include Adobe RGB, sRGB, ITU-R Rec. BT-709, SMPTE-C, and the Digital
Cinema Initiative reference projector (informally known as DCI-P3, also SMPTE-431-2) output
device spaces, in addition to space for a user-adjustable preset.
●
The user preset permits the setup of a custom color space emulation, with full control over the
desired RGB primaries, white point, white luminance, and gamma (display transfer function).
This Appendix will detail the operation and usage of these features provided on the LP2480zx monitor.
