HP Watermark and Image Retention Policy

The IPS monitor models are designed with IPS (In-Plane Switching) display technology which provides ultra-wide viewing angles and advanced image quality. IPS monitors are suitable for a wide variety of advanced image quality applications. This panel technology, however, is not suitable for applications that exhibit static, stationary or fixed images for long periods of time without the use of screen savers. These types of applications may include camera surveillance, video games, marketing logos, and templates that are displayed on the screen for a prolonged period of time. Static images may cause image retention damage that could look like stains or watermarks on the monitor's screen.

Monitors in use for 24 hours per day that result in image retention damage are not covered under the HP warranty. To avoid image retention damage, always turn off the monitor when it is not in use or use the power management setting, if supported on your system, to turn off the display when the system is idle.

Connecting USB Devices There are four downstream USB ports on the monitor (two on the rear and two on the side). NOTE: You must connect the USB hub cable from the monitor to the computer to enable the USB ports on the monitor. Refer to Step 4 in Connecting the Cables on page 8.

Software and Utilities

The disc that comes with the monitor contains files you can install on the computer:

| | |---|

NOTE: If the monitor does not include a disc, the items listed above can be downloaded from the HP monitors support Web site. See Downloading from the Internet on page 28 in this chapter.

#### The Information File

The .INF file defines monitor resources used by Microsoft Windows operating systems to ensure monitor compatibility with the computer’s graphics adapter.

This monitor is Microsoft Windows Plug and Play compatible and the monitor will work correctly without installing the .INF file. Monitor Plug and Play compatibility requires that the computer’s graphic card is VESA DDC2–compliant and that the monitor connects directly to the graphics card. Plug and Play does not work through separate BNC type connectors or through distribution buffers/ boxes.

#### The Image Color Matching File

The .ICM files are data files that are used in conjunction with graphics programs to provide consistent color matching from monitor screen to printer, or from scanner to monitor screen. This file is activated from within graphics programs that support this feature.

| | |---|

NOTE: The ICM color profile is written in accordance with the International Color Consortium (ICC) Profile Format specification.

Software and Utilities 27

Installing the .INF and .ICM Files

After you determine that you need to update, you can install the .INF and .ICM files from the disc or download them.

#### Installing from the Disc

NOTE: You may need to install the digitally signed monitor .INF and .ICM files manually from the disc in the event of an installation error. Refer to the HP Monitor Software Information file on the disc.

#### Downloading from the Internet

To download the latest version of .INF and .ICM files from the HP monitors support Web site:

Updating the Firmware HP recommends that you check for updated display firmware and install newer firmware if available. NOTE: By default, the monitor’s internal processor – which is required for firmware updating – is disabled. You must enable the processor before you can update the monitor firmware. In the OSD select Management > Manage Internal Processor and choose Enable to turn the processor on. If turning on just before attempting to update the firmware, wait approximately one minute for the internal processor to fully boot. To update the firmware via USB:

| | |---|

TIP: A bezel button shortcut, Display Info..., is provided on the fourth bezel button in the Z27x factory configuration. You can access this information page via this shortcut, unless the bezel button has been remapped. This information page also indicates whether the internal processor is on or off.

| | |---|

NOTE: The firmware is distributed as a compressed, signed tar file. Do not decompress the file before installing.

CAUTION: The monitor screen will turn black during the installation and the front panel LED will flash amber. Do not turn off the monitor during the firmware update.


Updating the Firmware 29

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 (u’v’)

Green Primary (u’v’)

Blue Primary (u’v’)

White Point Gamma Luminance

sRGB 0.451, 0.523 0.125, 0.563 0.175, 0.158 D65 sRGB 250 cd/m2 sRGB D50 0.451, 0.523 0.125, 0.563 0.175, 0.158 D50 sRGB 250 cd/m^2 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.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:

Adjusting Luminance

Though each preset is calibrated to a specific luminance level, the luminance can be adjusted postcalibration. 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.

To adjust luminance:

| | |---|

NOTE: The Adjust Luminance option displays the current luminance value to the right of the menu option.

Understanding the Z27x Image Adjustment Options

The Z27x contains a number of special image adjustment options that are designed to fit specific workflows in the media and entertainment industry. The following section describes these functions from the perspective of their application in these workflows.

#### Use Video Levels (16–235)

This option is designed to support the accurate display of “video legal” signals that include footroom below black and headroom above white. These types of signals are typically encountered when working with video signals that conform to the complete ITU-R BT.709 standard as this standard allows for excursions beyond black and white, rather than treating black and white as absolutes.

These signals are typically encountered in the following situations:

In all of these situations the video signal usually includes the BT.709 headroom and footroom. Without this option enabled when viewed in a computer monitor the blacks and shadows are lighter, the whites are darker, and colors have less saturation than the signal actually contains.

When this option is enabled the blacks will be clipped at the 8-bit value of 16 and the whites at the 8bit value of 235 (for 10-bit, the clipping will occur at the values of 64 and 960). The signal is then remapped to display the signal in the correct visual range.

It is important to note that the source and pre-processing of the source video will impact whether this setting should be enabled, but in many cases you will see a more-accurate image if you enable this option. Note that you may need to adjust the lightness of your editing application interface after enabling this setting.

To use video levels:

#### Overscan the Frame

Though by default the Z27x displays all pixels in the image, when screening video dailies or an edit revision it may be desirable to view the image in an overscanned mode, similar to how it is viewed on a consumer digital television. The Overscan Frame by 5% option will enlarge the image so that only that portion of the frame within the Action Safe region is displayed. Action Safe is defined as an area that begins 5% inside the edge of the frame.

To use the Overscan Frame mode:

Understanding the Z27x Image Adjustment Options 31

#### Show Only the Blue Channel

As the human is least-sensitive to changes in blue, most compression and encoding algorithms assign the least amount of bandwidth to the blue channel. Because of this, compression/encoding errors are most-easily seen when viewing the blue channel. The Z27x allows the user to view just the blue channel, temporarily turning the red and green channels off, so that the image can be inspected for these errors.

To view only the blue channel:

Using the Z27x Aspect Ratio Management Options

The Z27x includes a number of special aspect ratio management options that go far beyond what is typically found in a computer monitor. This section discusses these options, with a focus of how these options are integrated into specific workflows.

#### The “Fill To” Options

These options are used to determine how the source input is displayed onscreen if its resolution is different from the monitor’s native resolution of 2560×1440.

##### Fill to Source Aspect Ratio (Proportional)

This option will maintain the aspect ratio of the source input, making the image as large as possible, centering it in the monitor, and using 0% black to fill the unused areas of the screen. For example, a source input that is narrower than 16×9 will be displayed at full height with black bars to the left and right of the source image, and a source input that is wider than 16×9 will be the displayed at full width with black bars above and below the source image.

Fill to Source Aspect Ratio is the default and is the option most-suitable to the majority of workflows. Fill to Entire Screen (Non-Proportional)

This option will distort non-16×9 source aspect ratios to force them to fit within the monitor’s 16×9 aspect ratio. The resulting image will take up the entire display and will either be stretched horizontally (for narrower aspect ratios) or vertically (for wider aspect ratios).

Use Fill to Entire Screen if the source aspect ratio is irrelevant and you want the entire screen to be filled, regardless of the distortion that may be caused.

##### Fill to Screen Width (Proportional)

This option is to be used for specific workflows with source video that is narrower than the monitor’s native 16×9 aspect ratio. In some film workflows it is desired to render the animation or visual effects at a 4×3 aspect ratio and perform a “center extraction” for widescreen delivery. If enabled, this option will resize the source image so that the width matches the monitor width. Then the source image is centered vertically and the top and bottom of the image are cropped off, leaving a 16×9 “center extraction” of the 4×3 frame. The proportions of the source image are maintained.

The Fill to Screen Width option should be used when vertical center extractions are desired as part of the dailies or review screening process.

##### Fill to Screen Height (Proportional)

This option is to be used for specific workflows with source video that is wider than the monitor’s native 16×9 aspect ratio. In some film workflows it is desired to see a 16×9 horizontal extraction of a wider source aspect ratio. If enabled, this option will resize the source image so that the height matches the monitor height. Then the source image is centered horizontally and the top and bottom of the image are cropped off, leaving a 16×9 “center extraction” of the wider frame. The proportions of the source image are maintained.

The Fill to Screen Height option should be used when horizontal center extractions are desired as part of the dailies or review screening process.

##### Pixel-for-Pixel

This option is to be used for source video that has a lower resolution than the monitor’s native resolution of 2560×1440 and you wish to view the image without any scaling applied. For example, if your source image has a 1920×1080 resolution and you wish to inspect the pixels to ensure that there are no rendering issues in the displayed content, you may want to use this option.

This option has a specific functionality when the source video has a higher resolution than 2560×1440. This functionality will be covered in the next section.

##### “Fill To” Examples

The following illustrations summarize how a 4×3 source image is displayed using the “Fill to” options. The Fill to Screen Height option is not applicable to this source aspect ratio so it is not shown.

Using the Z27x Aspect Ratio Management Options 33

To change the way the source video is displayed onscreen:

| | |---|

NOTE: The Aspect Ratio Display page can be mapped to a bezel button function key for easy access. Refer to Changing the Bezel Button Functions on page 39 for instructions on mapping the bezel button function keys.

Working with 2K and 4K Digital Cinema Image Formats

The Z27x has direct support for the 2048×1080 and 4096×2160 image formats (containers) as specified in the Digital Cinema Initiatives (DCI) - Digital Cinema System Specification. The following table lists the supported formats.

DCI Level Horizontal Pixels Vertical Pixels Frame Rate

In addition, the display supports aspect ratio masking for the two standard aspect ratios, 1.85:1 and 2.39:1, within the DCI image container. When DCI aspect ratio masking is selected the source video is masked to only show the pixels within the specified aspect ratio. The following table lists the active pixels that will be displayed for each image container and aspect ratio.

######### DCI Container Size Aspect Ratio Horizontal Active Pixels Vertical Active Pixels

Finally, special display modes for 4K input resolutions are also provided to facilitate the display of 4K content on the Z27x.

#### Using the Digital Cinema Display Options

All of the digital cinema display options are located in the OSD on the Main Menu > Image Adjustment > Aspect Ratio Display page. These options are unavailable and the menu option dimmed unless one of the following resolutions is being displayed via the active video input:

| | |---|

NOTE: Though the Digital Cinema Options menu is available for the 3840 × 2160 resolution, the aspect ratio options are not available because 3840 × 2160 is not a DCI container size. To access the digital cinema display options:

The following DCI Aspect Ratio options are available in the Image Region section of the Digital Cinema Options page.

##### Show Entire DCI Container

This is the default option and will show the entire DCI 2048 × 1080 or 4096 × 2160 frame.

##### Crop to DCI 1.85:1 Aspect Ratio

This option crops 25 pixels from the left and right edges of the frame (for 2048-wide sources, 50 pixels from the left and right edges for 4096-wide sources). The resultant image is then displayed as specified using the Aspect Ratio Display options described in the previous section.

##### Crop to DCI 2.39:1 Aspect Ratio

This option crops 111 pixels from the top and bottom edges of the frame (for 2048-wide sources, 222 pixels from the top and bottom edges for 4096-wide sources). The resultant image is then displayed as specified using the Aspect Ratio Display options described in the previous section.

##### Show Cropped Region

When this option is enabled, rather than cropping and resizing the image to the selected aspect ratio, the image is not resized, but the region outside the desired aspect ratio is instead overlaid with a partially-transparent black mask. This option is useful, for example to check the top line in a 2.39:1 aspect ratio and see what information may be available, if the headroom needs to be adjusted via reframing.

##### Set Cropped Region Opacity

This option is available when Show Cropped Region is active and allows you to specify the amount of opacity applied to the cropped region. Adjust as needed to achieve the desired balance between the active and cropped regions of the frame.

##### Displaying 4K Source Video

Though it only has a native resolution of 2560 × 1440, the Z27x can receive and display a 4096 × 2160 or 3840 × 2160 input signal. Multiple scaling and display options are provided. To provide the highest quality display of 4K source video on the Z27x the scaling algorithm has been specifically tuned to provide a naturalistic scaling without any sharpness or edge enhancement.

When a 4096 × 2160 or 3840 × 2160 signal is input into the monitor, the following scaling options are available via the 4K Sources section of the Digital Cinema Options page. If DCI aspect ratio cropping has been selecting, these options are applied after the image is cropped.

##### Obey Aspect Ratio Display Option

This default option will display the image according to the selected “Fill to” Aspect Ratio Display option. Refer to Using the Z27x Aspect Ratio Management Options on page 32 for information on these options.

##### Scale and Show Center Extraction

If selected, the center 16×9 region of the frame will be displayed with the areas outside of this center region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the center extraction is dependent on whether the entire container or an aspect ratio is displayed.

##### Scale and Show Left Side of Frame

If selected, the left-most 16×9 region of the frame will be displayed with the areas outside of this left side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the left extraction is dependent on whether the entire container or an aspect ratio is displayed.

##### Scale and Show Right Side of Frame

If selected, the right-most 16×9 region of the frame will be displayed with the areas outside of this right side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the right extraction is dependent on whether the entire container or an aspect ratio is displayed.

##### Show 4K Source Video Pixel-for-Pixel

If the Aspect Ratio Display is set to Pixel-for-Pixel and the 4K Source option is set to Obey Aspect Ration Display Option, 4096 × 2160 and 3840 × 2160 source video can be displayed pixel-for-pixel. Two different display options are available, Show 4K Corner and Scroll 4K Region. Accessing these two options require that a specific function be mapped to one of the four bezel function buttons. Refer to Changing the Bezel Button Functions on page 39 for information on mapping the bezel function buttons. The following sections describe the usage of these two options.

###### Next 4K Corner

When viewing a 4K source as pixel-for-pixel, press the Next 4K Corner button to move, in order, between the following five positions:

The image will continue to switch between the five positions for each button press until Pixel-for-Pixel display is disabled.

###### Scroll 4K Region

When viewing a 4K source as pixel-for-pixel, press the Scroll 4K Region button to display navigation arrows, allowing you to move around the frame to the desired area. When this option is enabled, a pop-up window will appear in lower right region of the monitor that shows the entire 4K image and indicates the area of interest being show full-screen. Use the directional bezel buttons to shift the area of interest. When this option is turned off the pop-up will vanish, but the area of interest will continue to be displayed.

Using Picture-in-Picture (PIP) and Picture-beside-Picture (PBP)

The monitor supports both PIP, where one source is overlaid over another, and PBP, where one source is positioned adjacent to one another either horizontally (for landscape orientation) or vertically (for portrait orientation).

To use PIP or PBP:

Using PIP as a Confidence Monitor As the PIP is primarily designed to be used at as a confidence monitor – at 100% size for 1080- or 720-line content, including DCI 2K content – many of the Image Adjustments available for the main input are also available for use within the PIP. Refer to Understanding the Z27x Image Adjustment Options on page 31 and Working with 2K and 4K Digital Cinema Image Formats on page 35 for further information on these adjustments. The following adjustments are available within the PIP. None are enabled by default.

##### Use Video Levels (16–235)

If monitoring a video signal output from a video capture card such as an AJA Kona or Blackmagic Design Decklink, this option should usually be enabled as video levels are typically used in video post-production workflows.

##### Overscan Within PIP

Use this option if you wish to see how your video output will be displayed on a consumer television. This is especially useful when ensuring that the margins for lower third graphics are correct and nothing will be cut off on a consumer television.

##### Digital Cinema Options

If you display a 2048 × 1080 signal as a PIP, you can instruct the monitor to display either the full DCI container or crop the PIP to either the 1.85:1 or 2.39:1 aspect ratio. If cropping to an aspect ratio, the shape of the PIP will change to the chosen aspect ratio. Black bars will not be visible at the edges of the PIP.

Changing the Bezel Button Functions

You can change the top-level front bezel button functions from their default values so that when the buttons are activated you can quickly access commonly used commands.

The following commands can be mapped:

Changing the Bezel Button Functions 39

Changing the Bezel Function Button Mode

By default when any bezel button is pressed a menu appears to the left of the buttons, indicating the command assigned to each button. When the menu is displayed, you can press the desired button to execute an assigned command. Once you are familiar with the menu configuration you can disable

the function button label display and simply press the desired bezel button to execute the desired command. This will only disable the function button label display for the function button commands. Once you have opened the OSD the function labels will display.

To change the bezel function button mode:

Adjusting the Bezel Button LEDs

The bezel button LEDs have an automatic fade-out feature that is active by default. The LEDs will fade after the OSD timeout period. You can change the LED behavior so that they do not fade out and you can also adjust the brightness of the LEDs if the fade-out feature is disabled.

To disable the bezel button fade-out feature:

If the bezel button fade-out feature has been disabled (as described above), you can adjust the brightness of the buttons on the front bezel to different levels of ambient lighting.

To change the bezel button brightness:

You can also change the color of the button LEDs on the front bezel. You can make the button LEDs white or red, or set them to automatically change from white to red when ambient lighting is reduced. Red should be used when operating the monitor in low-light environments. The white LED color can negatively impact your eye's color sensitivity while red will not.

To change the bezel button color:

Using Auto-Sleep Mode

The display supports an OSD (On-Screen Display) option called Auto-Sleep Mode, that allows you to enable or disable a reduced power state for the display. When Auto-Sleep Mode is enabled (enabled

Adjusting the Bezel Button LEDs 41

by default), the monitor will enter a reduced power state when the host PC signals low power mode (absence of either horizontal or vertical sync signal).

Upon entering this reduced power state sleep mode, the monitor screen is blanked, the backlight is turned off and the power LED indicator turns amber. The monitor draws less than 0.5W of power when in this reduced power mode. The monitor will wake from the sleep mode when the host PC sends an active signal to the monitor (for example, if you activate the mouse or keyboard).

You can disable the Auto-Sleep Mode in the OSD. Press one of the five front bezel buttons to activate the buttons, and then press the bottom Open Menu button to open the OSD. In the OSD press Management > Auto-Sleep > Disable.

Using the On-Screen Display Menu

Use the On-Screen Display (OSD) to adjust the screen image based on your viewing preferences. To access the OSD, do the following:

Introduction to Color Calibration

The Z27x includes an internal color calibration and color management engine and does not require software to be installed on a host computer in order to be calibrated. The following section discusses the fundamentals of user calibration on the Z27x. A detailed discussion of calibration is covered in the HP DreamColor Z27x Advanced User Guide.

The Z27x has been pre-calibrated at the factory to accurately display six of the most-frequently used industry standard color spaces. In addition, all color spaces presets can be recalibrated by the user. The following table lists the out-of-the box calibrated color space presets and provides information on their calibrated configuration.

Preset Name Red Primary (u’v’)

Green Primary (u’v’)

Blue Primary (u’v’)

White Point Gamma Luminance

sRGB 0.451, 0.523 0.125, 0.563 0.175, 0.158 D65 sRGB 250 cd/m2 sRGB D50 0.451, 0.523 0.125, 0.563 0.175, 0.158 D50 sRGB 250 cd/m^2 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.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

As a display is used, the backlight ages and the light output changes. As a result, a color-critical display must be recalibrated from time to time to ensure color accuracy. HP recommends that the Z27x be recalibrated every one thousand hours of use. The number of hours since calibration can be displayed via the Display Information option in the Main Menu of the OSD or via the Show Display Information command.

HP supports a variety of color measurement instruments, from inexpensive solutions that sell for a few hundred dollars to colorimeters and spectroradiometers costing tens of thousands of dollars. The following measurement instruments are supported:

Please refer to the HP DreamColor Z27x Advanced User Guideor the Calibration Best Practices white paper for the recommended configuration of these instruments.

The HP DreamColor Calibration solution is available directly from HP.com and HP resellers. Contact the manufacturers of the other supported instruments for pricing and availability.

| | |---|

NOTE: As the connection to the Z27x is made via USB, the Photo Research and Konica Minolta units must have USB connection, which is optional on some models. Two different calibration workflows are supported:

This user guide only covers the onscreen menu-driven calibration option. Please refer to the HP DreamColor Z27x Advanced User Guideor the Calibration Best Practiceswhite paper for information on the XML-driven option.

#### Preparing to Calibrate

In order to calibrate, the Z27x internal processor must be enabled. To meet the energy savings requirements of Energy Star 6.0, the internal processor is disabled at the factory.

To enable the Z27x internal processor:

Once enabled, wait approximately one minute for the processor to fully boot before beginning calibration.

CAUTION: It is strongly recommended that calibration be performed in a darkened room. Stray light bouncing off the monitor will negatively impact calibration accuracy.

#### Calibrating the Z27x Using the Onscreen Menus

Once the internal processor has booted, connect the measurement instrument to one of the DreamColor USB ports on the bottom of the Z27x.

Introduction to Color Calibration 53


After 15–60 seconds, depending on the measurement instrument, the Z27x will display a message asking you how you wish to calibrate the monitor.

##### Recalibrate the Current Preset

This option will recalibrate the active color space using its current configuration. This is the recommended procedure for recalibrating a color space that is configured the way you need it to be. After choosing this option the display will show an instrument alignment target. Align your instrument with the center of the crosshairs then press the Start Calibration bezel button.

| | |---|

NOTE: If using the HP DreamColor Calibration Solution, be sure to rotate the ambient light filter out of the way before using the instrument. For other instruments be sure to remove the lens cap prior to calibration.

Depending on the instrument used, calibration may take between a few minutes and half an hour. The screen will display a variety of colors during the calibration process then display a calibration complete message at the end of calibration.

##### Select and Modify a Preset

This option allows you to choose the color space to calibrate and change the gamut, white point, gamma, and luminance targets. This is the recommended procedure if you want to modify a color space preset from its factory configuration

When this option is selected you will be presented with a series of screens from which you can choose the desired calibration targets. Each screen allows you to select from a set of standard options, as documented below. If you wish to create a custom set of calibration targets use the StudioCal XML option, documented in the Z27x Advanced User Guide.

The following standard options are provided for you to select from:

| | |---|

NOTE: Further information on these standard values is provided in the Z27x Advanced User Guide.

Once all of the options are selected the display will show a calibration target. Align your instrument with the center of the crosshairs then press the Start Calibration bezel button.

Depending on the instrument used, calibration may take between a few minutes and half an hour. The screen will display a variety of colors during the calibration process then display a calibration complete message at the end of calibration.

Auto EDID Update By default, the display automatically updates the display EDID when you switch color spaces. If Auto EDID Update is enabled, the EDID will be updated for all inputs every time you change the active color space preset. If Auto EDID Update is disabled, each input will be set to the factory default values for the Native color space. You can enable or disable Auto EDID Update in the OSD:

Preparing to Call Technical Support

If you cannot solve a problem using the troubleshooting tips in this section, you may need to call technical support. Have the following information available when you call:

C 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.

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.
