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 uvspace) 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.  
32 Appendix A Advanced Color Management Features and Usage  
 
Color Gamut and Color Space Coverage  
The LP2480zx monitor uses an LED-backlit LCD module that provides an extremely wide color gamut.  
This gamut was chosen to enclose a number of color spaces as defined by various standard output  
device specifications, which (along with other color-management features in this product’s electronics)  
permits the monitor to accurately emulate display devices conforming to these standards. The nominal  
native primary set, white point, and gamma of the LP2480zx, and those of the various supported  
standards, are provided in the table below:

† The Digital Cinema/SMPTE-431-2 reference projector gamut is not fully enclosed by the LP2480zx’s native gamut; when set  
to the DCI preset, the monitor will provide as accurate an emulation of this space as possible within its available gamut. The  
difference is primarily along the red-green edge of the DCI gamut, as the DCI red and green primaries are slightly outside the  
LP2480zx gamut. See the diagram below.  
Color Gamut and Color Space Coverage 33  
 
As plotted within the 1976 CIE uv’ color space, these gamuts are shown below:  
Figure A-1 Color Space Diagram  
Color Space Emulation  
As noted earlier, the LP2480zx has the capability of emulating a display that conforms to a number of  
standard output device specifications, such as sRGB, Adobe RGB, and et cetera. This emulation  
includes matching the specified primaries, transfer function (gamma), white point, and, where  
appropriate, white level (luminance) of the target specification. Preset color spaces are provided as  
described earlier, and in addition, the user may program custom spaces as desired. Full custom color  
space programming involves the selection of primaries, white point, gamma value, and et cetera, which  
may be accomplished using the optional HP/X-Rite calibration tool. However, the display luminance  
(brightness) and white point may be adjusted using the on-screen display (OSD) or HP Display Assistant  
software.  
The following sections describe the theory behind this emulation, the hardware provided to support it in  
the LP2480zx, and information on its usage.  
Theory of Operation  
In general, most display devices such as CRT- or LCD-based monitors, may be mathematically modeled  
as comprising two functions: first, a mapping of the input values (which we will assume for this discussion  
are in the form of “RGB” codes, that is, the relative values of red, green, and blue levels for each pixel  
in the image) to the intensity of light output by the device for each (this is the display’s transfer function,  
sometimes referred to as the gamma, for each of the three channels). This now “gamma adjusted” data  
must also be mapped to the specific primary colors and intensities provided by the display device for  
34 Appendix A Advanced Color Management Features and Usage  
   
each of the three channels (that is, exactly what will be output, in terms of light, for the given values of  
red, green, and blue). This may be expressed by the following diagram:  
Figure A-2 Model of Standard Display Device  
Here, the input RGB values are first modified by the appropriate transfer function (γR, γG, or γB); this  
operation may be viewed as being performed by three look-up tables (LUTs) of the appropriate width  
and depth. The modified RGB values (R, G, and B) are then mapped to the resulting output light levels  
of the correct intensity and color. This may be viewed as a matrix multiplication operation (A) involving  
the RGBvalues and the appropriate XYZ tristimulus values for the specific display device primaries,  
luminance, and white point in question:  
Figure A-3 Matrix Multiplication of Input Values  
In essence, the R, G, and Bvalues may be seen as “gain controls” on three light sources whose peak  
outputs are described as (XR,YR,ZR), (XG,YG,ZG), and (XB,YB,ZB). The display device itself – in this case,  
the LCD module used in the LP2480zx monitor – of course has its own native characteristics which may  
be modeled as described above. The problem of emulating a different (presumably, standard) output  
device characteristic is then one of adding a “transform” block (T, in the diagram below) which will modify  
this native characteristic such that the overall system emulates the desired performance. In terms of the  
above diagram, if the combination of γS and AS represent the desired standard characteristic, it is the  
function of the transform block T to correct the native display characteristics (γD and AD) such that the  
output (TD) of this system matches that of the standard device, for the same input values:  
Color Space Emulation 35  
Figure A-4 Correcting Native Display Characteristics  
It can be shown that the required transform (T) may be implemented as a pair of appropriately-sized  
look-up tables (LUTs), on either side of a 3 x 3 matrix multiplication. The LUT preceding the matrix  
multiplication (the “pre-LUT”) implements the desired standard transfer function or gamma response  
curve, such that input values are correctly mapped per that standard into a “linear light” space. The  
required matrix for the color remapping (which is referred to as R) is a combination of the matrix that  
transforms RGBto XYZvalues under the target standard (AS), and the inverse of the corresponding  
matrix for the existing display device (AD). In other words,  
R = AD-1AS  
This stage must then be followed by a second look-up table (the “post-LUT”), which linearizes the  
existing display device; specifically, it contains the inverse of the display’s transfer functions γD(R,G,B)  
.
The complete transform block (plus the LCD module) as implemented in the LP2480zx monitor is then:  
Figure A-5 Color Space Conversion Hardware in the LP2480zx  
36 Appendix A Advanced Color Management Features and Usage  
Note that since the look-up tables for the three channels (R, G, and B) are independent, differences in  
the display device’s transfer function across these three, along with any minor errors in the display white  
point, may be “nulled out” using the look-up tables, in addition to the operations required for the color  
space emulation as described above. In the LP2480zx, these functional blocks are implemented as part  
of the “front end” electronics, in addition to the usual scaler/controller functions of a standard monitor.  
Due to the limitations imposed by the components used in the LP2480zx front end, full color space  
emulation functionality is not available on the analog composite, component, or S-Video inputs*; it is,  
however, fully supported when using the DVI-I (both analog and digital sections), HDMI, and DisplayPort  
inputs IF the input video is provided using RGB encoding. Color space emulation is not provided on any  
input for video using YUV/YCBCR encoding. The complete matrix of feature support for the various inputs  
and signal encodings is provided in the table on the following page.  
NOTE: * These inputs connect between the pre-LUTs and the 3x3 matrix multiplier; therefore, re-  
mapping of the input values per the desired output device transfer function is not possible.  
Selection of the desired standard color space, or selection of a user-defined custom color space setting,  
may be achieved through the on-screen display (OSD) menus, the HP Display Assistant software, or  
the optional HP/X-Rite calibration software. These provide the correct programming of the color  
management hardware described above as needed for the desired color space characteristics.  
NOTE: Refer to the monitor’s DDC/CI and USB communication specification for more details.  
Summary of Color Space Selection Availability  
As noted, the selection of output device color space presets and the resulting emulation of the desired  
display characteristics, is not available for all LP2480zx inputs or all color encodings. Basically, this  
functionality is available only when a progressive-scanned RGB input is provided by the video source.  
YUV (which is considered here as including YCBCR, et cetera) encoding cannot be used, nor can color  
space emulation be supported for interlaced video (as the LP2480zx must convert any interlaced video  
to YUV, if not in this form already, in order for the built-in de-interlacing to operate correctly). When  
support for the standard or user-defined color space presets cannot be provided, these options will be  
“grayed out” on the OSD, and adjustments for image Hue and Saturation will be provided instead.

10 bits/color LCD Module  
As noted earlier, the LCD module in the LP2480zx monitor provides a 10 bits/color (30 bits/pixel) input,  
with true 10-bit drivers within the LCD itself. This means that each primary (red, green, and blue) may  
be controlled over 1,024 steps (input codes 0 to 1023) from the black level to the white (peak luminance  
for that color). This results in over 1.07 billion separate colors available within the display’s gamut, versus  
approximately 16.7 million for a conventional 8 bits/color display.  
This increase in dynamic range is required for the accurate display of color within the wide gamut  
provided by the LP2480zx’s LCD, and especially for achieving the necessary degree of color accuracy  
within the more restricted gamuts that this monitor is capable of providing when emulating various  
standard output devices. Increasing a display’s color gamut – the area covered by the display when the  
primaries are plotted on a standard chromaticity diagram – would result in a greater difference between  
adjacent colors if the degree of control (bits per color) for each primary were not also increased.  
Increasing the bit depth of the display drivers achieves this without the possibility of undesirable image  
artifacts which may result from temporal or spatial dithering as may sometimes be used with an LCD of  
lower inherent accuracy. (The LP2480zx’s “front-end” electronics are also, however, capable of  
providing temporal dithering, if needed, to increase the delivered accuracy beyond the 10 bits/color level.  
By default, this is used only between the pre-LUT and the 3x3 matrix multiplier stage; temporal dithering  
is possible but normally disabled at the 30-bit connection between the post-LUT and the LCD module  
itself.)  
With most video sources (which typically provide video information at the standard 8 bits/color or 24  
bits/pixel), and across all of the LP2480zx’s various inputs, the increased accuracy of the LP2480zx  
LCD module is used to provide more accurate color within the selected standard color space. However,  
30-bit sources may also be directly supported using the DisplayPort 1.1 and HDMI 1.3 inputs only. This  
will be of greatest benefit when the LP2480zx is used in the wider-gamut modes (such as Full, Adobe  
RGB, DCI).  
LED Backlight Unit  
As noted earlier, the LP2480zx monitor employs a backlight consisting of an array of red, green, and  
blue light-emitting diodes (LEDs) rather than the more typical cold-cathode fluorescent lamps (CCFLs)  
on most LCD monitors. This provides several significant advantages, in addition to the obvious benefit  
of a wider color gamut (that is, more saturated primaries) than can currently be achieved using CCFLs.  
In the LP2480zx, the red, green, and blue LED arrays are controlled both collectively and separately by  
a dedicated backlight controller, which permit both very accurate setting of the display luminance as  
well as control of the white point of the unit. Color sensors in the backlight unit feed color information  
back to the controller constantly, permitting an accurate white point to be maintained.  
Compared with CCFLs, which have only a limited range of brightness control available and a fixed  
emission spectrum, the LED backlight used here provides a very wide range of both brightness and  
color control. The white point may be adjusted over a range corresponding to a correlated color  
temperature (CCT) of 4,000K to 12,000K, including support for all standard white points with CCTs within  
this range. In addition, the white luminance may be adjusted from a maximum of approximately 250 cd/  
m2 down to 50 cd/m2, making the LP2480zx suitable for use in low-light environments; at the lower  
38 Appendix A Advanced Color Management Features and Usage  
   
brightness settings, both its white luminance and black level compare favorably with those of traditional  
CRT displays. (At the low end of this range, the monitor’s black level will typically be approximately 0.05  
cd/m2.)  
As with several other parameters set in the color space presets, the programming of the backlight  
controller is managed either through the LP2480zx’s on-screen display (OSD), or by using the HP  
Display Assistant software.  
Transfer Function (Gamma)  
As noted briefly in the previous section on Color Space Emulation on page 34 in this Appendix, display  
devices typically impose a non-linear transfer function on the input video data, in terms of how the  
intensity of the light output by the device varies versus these inputs. This is often referred to as the  
display’s “gamma” response characteristic, as one simple model for this behavior is a power-function  
curve (in which the exponent is typically represented by the Greek letter gamma, γ) as follows:  
Figure A-6 Gamma Curve Response Characteristic  
This model, with a “gamma” value of about 2.2 – 2.5, describes the actual response of a standard CRT  
display fairly well,* and so was assumed for years to be the typical response curve of an electronic  
display device. As it turns out, encoding image information under the assumption of an output device  
response of this nature has other advantages, and so it remains very common for standard output device  
specifications to require a transfer function or response curve which is of this general nature. The most  
common modification to this simple model as seen in many current output device or image encoding  
standards is the addition of a linear region at the lower end of the response curve, as shown in the  
following diagram. This linear region avoids problems, which otherwise would result from applying the  
inverse of the response curve (in image encoding), as otherwise the slope of the curve would be  
changing very rapidly in the low-luminance regions of the image.  
NOTE: * The biggest shortcoming of the simple gamma curve model as given, with respect to CRT  
displays, is that the black level of the input signal (assumed to be zero) does not generally result in  
exactly zero luminance for a properly-adjusted CRT. This requires the addition of an offset term into the  
model. However, the basic model as shown here remains an adequate description for most non-critical  
work.  
Transfer Function (Gamma) 39  
 
Figure A-7 Low Linear Region Response Curve  
A generalized model for the display response curve accommodating the addition of a linear section as  
shown above thus requires the specification of four parameters in addition to the “gamma” exponent  
value:  
For input values (I) A0:  
Y = I/A1  
For input values (I) > A0′  
Y = [(I + A2)/(1 + A3)]γ  
The response of the LP2480zx is automatically set to the correct standard as part of the color-space  
selection, using either the on-screen display (OSD) or using the HP Display Assistant software, or using  
the optional HP/X-Rite color calibration tools. Independently programming a custom response (as in the  
case of the user-defined custom color space preset) requires use of the HP/X-Rite calibration tools.  
Using the software provided with this calibration product, the display response may be programmed  
using the four-value-plus-gamma model described above.  
Several of the standard color space specifications supported by the LP2480zx require the use of the  
“four-value” model, as they include a linear section in the response curve as described above. Of course,  
even the simple “gamma-only” model may be accommodated within the four-value model, by setting  
the A0, A2, and A3 parameters to zero, and A1 to a value of 1.0. The values used to describe the response  
for the standard color spaces or output device specifications supported by the LP2480zx are listed in  
the table below.

Entering User Modes  
The video controller signal may occasionally call for a mode that is not preset if:  
You are not using a standard graphics adapter.  
You are not using a preset mode.  
It this occurs, you may need to readjust the parameters of the monitor screen by using the on-screen  
display. Your changes can be made to any or all of these modes and saved in memory. The monitor  
automatically stores the new setting, then recognizes the new mode just as it does a preset mode. In  
addition to the factory preset modes, there are twenty user modes that can be entered and stored.  
Energy Saver Feature  
When the monitor is in its normal operating mode, the monitor uses less than 90 watts of power and the  
Power light is green.  
The monitor also supports a reduced power state. The reduced power state will be entered into if the  
monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon  
detecting the absence of these signals, the monitor screen is blanked, the backlight is turned off, and  
the power light is turned amber. When the monitor is in the reduced power state, the monitor will utilize  
less than 3 watts of power. There is a brief warm up period before the monitor will return to its normal  
operating mode.  
Refer to the computer manual for instructions on setting energy saver features (sometimes called power  
management features).  
NOTE: The above power saver feature only works when connected to computers that have energy  
saver features.  
By selecting the settings in the monitor's Energy Saver utility, you can also program the monitor to enter  
into the reduced power state at a predetermined time. When the monitor's Energy Saver utility causes  
the monitor to enter the reduced power state, the power light blinks amber.

Power Cord Set Requirements  
The monitor power supply is provided with Automatic Line Switching (ALS). This feature allows the  
monitor to operate on input voltages between 100–120V or 200–240V.  
The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use  
in the country where you purchased the equipment.  
If you need to obtain a power cord for a different country, you should purchase a power cord that is  
approved for use in that country.  
The power cord must be rated for the product and for the voltage and current marked on the product's  
electrical ratings label. The voltage and current rating of the cord should be greater than the voltage and  
current rating marked on the product. In addition, the cross-sectional area of the wire must be a minimum  
of 0.75 mm² or 18 AWG, and the length of the cord must be between 6 feet (1.8 m) and 12 feet (3.6 m).  
If you have questions about the type of power cord to use, contact an authorized HP service provider.  
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon  
it or against it. Particular attention should be paid to the plug, electrical outlet, and the point where the  
cord exits from the product.  
Japanese Power Cord Requirements

E LCD Monitor Quality and Pixel Policy  
The TFT monitor uses high-precision technology, manufactured according to HP standards, to  
guarantee trouble-free performance. Nevertheless, the display may have cosmetic imperfections that  
appear as small bright or dark spots. This is common to all LCD displays used in products supplied by  
all vendors and is not specific to the HP LCD. These imperfections are caused by one or more defective  
pixels or sub-pixels.  
A pixel consists of one red, one green, and one blue sub-pixel.  
A defective whole pixel is always turned on (a bright spot on a dark background), or it is always off  
(a dark spot on a bright background). The first is the more visible of the two.  
A defective sub-pixel (dot defect) is less visible than a defective whole pixel and is small and only  
visible on a specific background.  
To locate defective pixels, the monitor should be viewed under normal operating conditions, in normal  
operating mode at a supported resolution and refresh rate, from a distance of approximately 50 cm (20  
in).  
HP expects that, over time, the industry will continue to improve its ability to produce LCDs with fewer  
cosmetic imperfections and HP will adjust guidelines as improvements are made.
