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.
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.
As plotted within the 1976 CIE u’v’ 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.
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.
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.
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.

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.
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 Dis

The color gamut, white point, and response curve seen in this mode are therefore those of the LCD panel itself, but corrected to their nominal values as accurately as possible.
B Troubleshooting Solving Common Problems The following table lists possible problems, the possible cause of each problem, and the recommended solutions.
