A Advanced Color Management Features and Usage The HP LP2480 zx monitor provid es several advanced fe atures th at make it pa rticul arly well-suited to color-critical applications, such as professional computer graphics d evelopment, video prod uction, and similar uses. These include: ● True 10-bit drivers in the L CD panel itself, and the ability to support true 10 bits/color (30 bits/pixe l) video through the DisplayPort 1.1 and HDMI 1.3 inputs. ● An LED backlight unit (instea d of the usual cold-cathode fluo rescent, or CCFL type) with independent co ntrol of the red, gree n, and blue channels. This permits wh ite point control usin g the backlight, and a very wide range of white level (p eak luminance) settings. ● The LED backlight, coupled with specially-se lected color filters in th e LCD, provid es a very wide gamut (133% of th e 1953 NTSC g amut area, as expressed in the CIE 1976 u ′v ′ spac e) for this monitor. As this gamut encloses a number of sta n dard outp ut device ga muts, such as Adobe RG B and sRGB/Rec. 709, this enables accur ate emulation of t hese standards by means of gamut - adaptation capabilities bu ilt 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” electron ics provides su pport for the gamut ada ptation mentioned above, including numerous factory-adjus ted color space pr e sets, which permit the user to quickly set up the monito r to accurately emu late these standa rd output device specification s. The factory- calibrated presets include Adobe RGB, sRGB, IT U-R Rec. BT-709, SMPTE-C, and the Digital Cinema Initiative refe rence projec tor (informa lly known as DCI-P3, al so SMPTE-431-2) outp ut device spac es, in addition to sp ace for a user-adjustable preset . ● The user preset permits the setup of a custom co lor space emulation , with full control ov er the desired RGB primarie s, white point, white lumi nance, and gamma (display transfer function). This Appendix will detail the oper ation and usage of these features provided on the LP2480zx monitor. 32 Appendix A Advanced Color Manage ment Features and Usage
Color Gamut and Color Space Coverage The LP2480zx monitor uses an LED-backli t LCD modu le that provides an extreme ly wide color gamut. This gamut was chosen to e nclose a number of co lor spaces as defined by various standard output device specifications, which (along with other color-m anagement features in this product’s electronics) permits the monitor to accurately emulate disp lay dev ices conforming t o these stan dards.

The difference is primarily along the red-g reen edge of the DCI gamut, as the DCI red and gr een primaries are slightly outside the LP2480zx gamut. See the diagram below. Color Gamut and Color Sp ace Coverage 33
As plotted within the 1976 CIE u ’ v ’ color space, these ga muts are shown below: Figure A-1 Color Space Diagram Color Space Emulation As noted earlier, the LP2480zx ha s the capability of emulating a disp lay that conforms to a number of standard outp ut device specifications, such as sRGB, Adobe RGB, and et cetera. This emulati on includes matching the specified prima ries, tran sfer fu nction (gamma), white point, and, wh ere appropriate, white level (lum inance) of the target specif ication. Prese t colo r spaces are provided as described earlier, and in addition, the user may pr ogram custom spaces as desired. Full custom co lor space programming involves the se le ction of primaries, white point, gamma value, and et cetera, which may be accomplished usin g the optional H P/X-Rite calibra tion tool. Howeve r, the display luminance (brightness) and wh ite point may be adjusted usin g the on-screen display (OSD ) or HP Display Assistant software. The following sections describe the the ory behind this emulation, the hardware provid ed to support it in the LP2480zx, and in formation on its usage. Theory of Operation In general, most display devices suc h as CRT- or LCD- based monitors, may be mathemat ically modeled as comprising two functions: first, a mapping of the input values (which we will assume for this discussion are in the fo rm of “RGB” codes, th at is, the relative values of red, gree n, and blue leve ls for each pixel in the image) to the inte nsity of light output by the device for each (th is 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 map ped to the specific primary co lors and intensities provid ed by the display device for 34 Appendix A Advanced Color Manage ment 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 expre ssed by the followin g diagram: Figure A -2 Model of Standa rd Display Device Here, the input RGB va lues are first modified by the ap propriate transfer function ( γ R , γ G , or γ B ); this operation may be viewed as b eing performed by thre e look-up tables (LUTs) of the appropriate width and depth. The modified RGB values (R ′ , G ′ , and B ′ ) are then map ped to the resulting output light levels of the correct intensity and color. This may be viewed as a matrix multiplication operation ( A ) involving the R ′ G′ B′ values and the appropriate XYZ tristimulus values for the spec ific display device primaries, luminance, and white p oint in question: Figure A -3 Matrix Multiplicat ion of Input Values In essence, the R ′ , G ′ , and B ′ valu es may be seen as “gain controls” on three light sources whose peak outputs ar e described as ( X R , Y R , Z R ), ( X G , Y G , Z G ), and ( X B , Y B , Z B ). The display device it self – in this case, the LCD module used in the LP2 480zx monitor – of course has its own native characteristics which ma y be modeled as d escribed above. T he problem of em ulating a different (presumab ly, standard) output device characterist ic is then one of adding a “trans form” block (T, in the diagram below) which wil l modify this native characteristic such that the overall system emulates the desired performance. In terms of the above diagram, if the combina tion of γ S and A S represent the desired standar d characteristic, it is the function of the transform block T to correc t the native displa y characteristics ( γ D and A D ) such that the output (TD) of this system ma tches that of the standard devic e, fo r the same input va lues: Color Space Emulation 35
Figure A-4 Correcting Native Di splay Characteristics It can be shown tha t the required tran sform (T) may be implemented as a pa ir of appropriately-sized look-up tables (LUTs), on either side of a 3 x 3 ma trix multiplicatio n. T he LUT preceding the matrix multiplication (the “pre-LUT”) impleme nts the desired standard transf er function or g amma response curve, such that input values are correctly ma pped per that sta ndard into a “linear light” space. The required matrix for the color rema pping (which is referred to as R ) is a combination of the matrix that transforms R ′ G′ B′ to X ′Y ′Z ′ values under the target standard ( A S ), and the inverse of the correspon ding matrix fo r the ex isting disp lay device ( A D ). In other words, R = A D -1 A S This stage must th en be followed b y a second loo k-up table (the “post-LUT”), wh ich linearizes the existing display device; specifically, it contains the inverse of the display’s transfer functions γ D(R,G,B) .

Note that since the look-up tables for the three c hannels (R, G, and B) are independent, differ ences in the display device’s transfer fun ction across these th re e, along wi th any minor errors in the display whi te point, may be “nulled out” using th e look-up table s, in add ition to the operations required fo r the color space emulation as describ ed above. In the LP2480zx, these functional blocks are implemented as part of the “front end” electro nics, in addition to the usu al scaler/controller functions of a standard monito r. Due to the limitations imp osed by the compon ents used in the L P2480zx front end, ful l color space emulation functionality is not ava ilable on the analog composite, component, or S-Video inputs*; it is, however, fully supported when u sing the DVI-I (both a nalog and dig ital sections), HDMI, and Disp layPort inputs IF the input video is provided using RGB encoding. Color space emulation is no t provided on any input for vide o using YUV/YC B C R encoding. T he complete matrix of f eature suppor t for the various inpu ts and signal e ncodings is provid ed in the tab le on the followin g page. NOTE: * These inputs co nnect between the pre-LUTs a nd the 3x3 matrix multip lier; therefore, re- mapping of the inp ut values per the desi red outp ut device transfer function is not possible. Selection of the desired stan dard color space, or sele ction of a u ser-defined custom colo r space setting, may be achieved through th e on-screen display (O SD) menus, the HP Display Assistant softwar e, or the optional HP/X -Rite calibration so ftware. These pr ovide the correct programming of th e color management hardware described above a s needed for the desired color sp ace characteristics. NOTE: Refer to the monitor’s DDC/CI and USB co mmunication specification for more details. Summary of Color Space Selection Availability As noted, the s election of outp ut device color spac e presets and the resulting emu lation of the desired display characteristics, i s not available for all LP2480zx inpu ts or all color encodings. Basically, this functionality is availa ble only when a pro gressive-scanned RGB input is provided by the video source. YUV (which is considered here as including YC B C R , et cetera) encoding can not be used, nor can color space emulation be supporte d for interlaced video (a s the LP2480zx must convert any interl aced video to YUV, if no t in this fo rm already , in order for the bui lt-in de-interlacing to operate correctly). Wh en support for the standard or user-defined color space presets cann ot be provided, these options will be “grayed out” on the O SD, and adjustments fo r image Hue and Sa turation will be provided instead.

Input used Color enc oding Scan format Resu lt Component, CVBS, S-Video YUV (RGB not suppo rted) Either Color Spac e presets: disabled Hue/Saturation controls: enabled 10 bits/color LCD Module As noted earlier, the LCD modul e in the LP2480zx moni to r provides a 10 bits/ color (30 bits/pix el) input, with true 10-bit drivers within th e LCD itself. This means th at each p rimary (red, green, and bl ue) may be controlled over 1,024 ste ps (input codes 0 to 1023) from th e black level to the white (p eak luminan ce 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 conv entional 8 bits/color display. This increase in dynamic ran ge is required for the a ccurate display of color within the wid e gamut provided by the LP2480 zx’s LCD, and especially for a chieving the n ecessary degree of color accuracy within the more restricted gamuts that this moni tor is capable of providing whe n emulating various standard output devices. Increa sing a display’s color gamu t – the area co vered by the disp lay when the primaries are plot ted on a stan dard chromaticity diag ram – would result in a greater differ ence between adjacent colors if the degree of control (bits pe r color) for each primary were not also increased. Increasing the bit depth of the display drivers achieves this with out the possibility of undesirable image artifacts which may result from temporal or spatial ditherin g as may sometimes be used with an LC D of lower inherent accura cy. (The LP2480zx’s “front-e nd” electronics are also , however, capable of providing temporal ditherin g, if needed, to incre a se the delivered accuracy beyond the 10 bits/color level. By default, this is used only between the pre-LUT a nd the 3x3 matrix multiplier stage; temporal dithering is possible but n ormally disabled at the 30 -bit connection between the post-LUT an d the LCD module itself. ) With most video sources (which typica lly provide vi deo information at th e standard 8 bits/colo r or 24 bits/pixel), and across all of the LP2480zx’s vari ous inputs, the increased ac curacy of the LP24 80zx LCD module is used to p rovide more accura te color within the selected standa rd color spac e. 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 be nefit when the LP2480zx is used in the wider-gam ut modes (such as Full, Adobe RGB, DCI). LED Backlight Unit As noted earlier, the LP24 80zx monitor employs a ba cklight consisting o f an array of red, green, and blue light-emitting diodes (LEDs) rather than the more typical cold-c athode fluorescent lamps (CCFLs) on most LCD monitors. This provides several sig nif icant advantages, in addition to the obvious benefit of a wider color gamut (tha t is, more saturated pr ima ries) than can currently be achie ved using CCFLs. In the LP2480zx, the red, gre en, and blue LED arra ys are controlled both colle ctively and separa tely by a dedicated b acklight controller, wh ich permit both very accurate setting of the display lu minance as well as control of the white point of the un it. Colo r sensors in the backlig ht unit feed color informa tion back to the controller co nstantly, permitting an accu rate white point to be maintained. Compared with CCFLs, which have only a limited range of brightne ss control available a nd a fixed emission spectrum, the LED backlight used here pr ovides a very wide range of bo th brightness and color control. Th e white point may be a djusted over a ra nge corresponding to a correla ted color temperature (CCT) of 4,000K to 12,000K, including su pport for all standard white points with CCTs within this range. In addition, the white lumina nce may be adjusted from a ma ximum of approximat ely 250 cd/ m 2 down to 50 c d/m 2 , making the LP2480zx sui table for use in low-li ght environments; at the lowe r Table A-2 Supported Signal Inputs and Color Space Ma trix (continued) 38 Appendix A Advanced Color Manage ment Features and Usage
brightness settings, b oth its white luminance and bl ack level compare f avorably with th ose of traditi onal CRT displays. (At th e low end of this range, the moni tor’s black level will typically be approximately 0.05 cd/m 2 .) As with several other p arameters set in the color sp ace presets, the programming of the backlight controller is manage d either through the LP2480zx ’s on-screen display (OSD ), or by using th e HP Display Assistant software. Transfer Function (Gamma) As noted briefly in the previo us section on Color Space Emulation on page 34 in this Appendix, displa y devices typically impose a non-lin ear transfer fu nction on the input video d ata, in terms of how the intensity of the light output b y the device varies ve rsu s these inputs. T his is often referre d to as the display’s “gamma ” response characte ristic, a s one simple model for this behavior is a p ower-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 th e actual response of a standard CRT display fairly well,* and so was assumed fo r years to be the typical respo nse curve of an electronic display device. As it turns out, encod ing image information u nder the assumption o f an output device response of this nature h as other advantages, an d so it remains very common for standard output device specifications to require a transfer function o r resp onse curve which is of this general natu re. The most common modification to this simple model as seen in many current ou tput device or image encoding standards is the additio n of a linear re gion at th e lower end o f the response curve, as shown in the following dia gram. This linear re gion avoids prob le ms, which otherwise would re sult from applying the inverse of the response curve (in imag e encoding), as otherwise the slop e of the curv e would be changing very rapidly in the low-luminance regions of the imag e. NOTE: * The biggest shortcoming of the simp le gamma curve model a s given, with respe ct to CRT displays, is that the black level of the input sign al (ass umed to b e zero) d oes not ge nerally re sult in exactly zero luminance for a properly-adjus ted CRT. This requires the a ddition of an offset te rm into the model. Howe ver, the basi c model as shown here rema ins an adequate de scription for most non-critical work. Transfer Function (Gamma) 39
Figure A-7 Low Linear Region Resp onse Curve A generalized mode l for the display resp onse curve accommodatin g the addition of a linear section as shown above thus require s the specif ication of fo ur parameters in addition to the “gamm a” exponent value: For input values (I) ≤ A 0 : Y = I/A 1 For input values (I) > A 0 ′ Y = [(I A 2 )/(1 A 3 )] γ The response of the LP2480zx is automatically set to the correct standard as pa rt of the co lor-space selection, using eith er the on-screen display (O SD) or using the HP Display Assistan t software, or using the optional HP/X-Rite color calibration tools. Ind e pendently program ming a custom response (a s in the case of the user- defined custom color space preset) re quires use of th e HP/X-Rite calibra tion tools. Using the software provided with this calibration product, the display response may be programmed using the four-val ue-plus-gamma model described above. Several of the standa rd color space specificati ons supported b y the LP2480zx require the use of the “four-value” model, as they include a line ar section in the response cu rve as described above. Of course, even the simple “gamma-only” mode l may be accommodat ed within the fo ur-value model, by setting the A 0 , A 2 , and A 3 parameters to zero, and A 1 to a value of 1.0. The values used to describe the response for the standard color spaces o r output device sp ecifications supported by the LP2480 zx are listed in the table below.

E LCD Monitor Quality and Pixel Policy The TFT monitor u ses high-precision techno logy, manufactured accordin g to HP standards, to guarantee trouble-free performanc e. Nevertheless, the display may have cosmetic imperfections that appear as small b right or dark sp ots. This is commo n to all LCD displa ys used in products supp lied by all vendors and is not sp ecific to the H P LCD. Thes e imperfections are caused by one or more defe ctive pixels or sub-pixels. ● A pixel consists of one red, o ne green, and one blue sub-pixel. ● A defective whole pixel is always turned on (a br ight spot on a dark background), or it is a lways off (a dark spot on a bright backgroun d). The first is the mo re visible of the two. ● A defective sub-pixel (dot defect) is less visible than a defective whol e pixel and is small and only visible on a spe cific background. To locate defective pixe ls, the monitor should be vie wed under norma l operating cond itions, in normal operating mode at a su pported resolutio n and refresh rate, from a distance of approximately 50 cm (20 in). HP expects that, over time , the industry will co ntinue to improve its ability to produce LCDs with fewer cosmetic imperfections and HP will adjust guidelines as improvements are made. 53
