Fill to source aspect ratio (proportional) This option maintains the aspect ratio of the source input, making the image as large as possible, centering it in the display, 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.
and the top and bottom of the image are cropped off, leaving a 16×9 “center extraction” of the Academy 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. The following illustration shows the visual result when a 1024×768 source input is displayed on the display with the Fill to screen width ratio (proportional) option enabled.
Pixel-for-pixel This option is for source video that has a lower resolution than the display’s native resolution of 2560×1440 and you wish to view the image without any scaling applied. If enabled, this option will display the source input in its native size and fill the remainder of the frame with 0% black. The following illustration shows the visual result when a 2048×1080 source input is displayed on the display with the pixel-for-pixel option enabled.
Digital cinema aspect ratio masking 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 digital cinema masking is enabled, the source signal is masked to only show the pixels within the chosen 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 2048 × 1080 1.
Mask to DCI 2.39:1 aspect ratio This option masks the top- and bottom-most 111 pixels of the 2048-wide frame. The resultant image is then displayed as specified using the image scaling options described in the previous section. The following illustration shows the a DCI source cropped to 2.39:1. Show masked region When this option is enabled, a partially-transparent mask is used instead of an opaque mask. This option is useful, for example to check the topline in a 2.
Working with markers The display includes a full set of marker overlays that can be used to indicate specific areas or regions of the frame. Multiple standard markers are included. Film aspect ratio markers Markers are provided for the standard theatrical aspect ratios 1.85:1 and 2.39:1. These markers will place a line at the film aspect ratio edge of both 17:9 (2048×1080) and 16:9 (2560×1440, 1920×1080, or 1280×720) source inputs.

The crosshair is 300 pixels wide and 300 pixels high. ● Thirds crosshair: provides four crosshairs, dividing the screen into thirds horizontally and vertically. The crosshairs will be properly positioned for both 17:9 and 16:9 source inputs.
Marker element The StudioCal XML schema allows for the definition of up to ten lines per custom marker. To support this, a marker parent element is used to enclose the information for each marker. This element contains two tags, an “entries” tag to specify the number of lines in the custom marker and a “product” tag to define the display the markers are designed for. The “entries” tag supports integer values between 1 and 16. The “product” tag currently supports only two values, “Z31x” and "Z27x".
○ blue ○ cyan ○ magenta ○ yellow The element should be structured as follows: Custom marker example The following is an example of a StudioCal XML file showing the usage of the marker tags. The example draws two lines to indicate the 4:3 caption safe area, as defined in EBU R 95.
4. The display will scan the secondary inputs for a valid input and use that input for the PIP picture. If you want to change the PIP input, select Assign inputs in the OSD and select the desired input (DisplayPort 1, DisplayPort 2, HDMI 1, HDMI 2, or USB Type-C). 5. If you want to change the size of the PIP, select PIP position and size in the OSD, and then select either Maximum, Default, Minimum, or Custom. At maximum size, the PIP will display pixel-for-pixel all input formats up to 2048×1080.
Custom video input names Custom input names can be assigned using XML as part of the StudioCal XML schema. See Using the StudioCal XML schema on page 71 for complete information on the StudioCal XML schema. Once a custom name has been created for an input it will be available as an option on the Rename inputs menu until a new custom name is assigned or a Factory reset is performed. There are two elements associated with custom video input names.
Using the KVM switch Two USB inputs can be bound to specific video inputs, providing the functionality of a KVM switch. This capability is disabled by default. The KVM switch function allows you to control two separate computers from the display.

3 Display calibration The display is color critical, so it can be calibrated to meet your production requirements and recalibrated to maintain color accuracy. The display is self-calibrated with all calibration algorithms running internally, so no host-based software is required. The display also includes an integrated XYZ colorimeter, enabling standalone calibration. For those that prefer to use an external instrument, a wide variety of third party measurement instruments are supported.
TIP: To determine if the processor is disabled, look at the Main menu in the OSD. If the Calibration menu is unavailable, the processor is disabled. To enable the internal processor: 1. Press one of the front bezel buttons to display the button labels, and then press the Open Menu button to open the OSD. 2. Select Management, and then select Internal processor. 3. Select Enable calibration to turn the processor on. 4. Press the Exit button to close the OSD.
Calibration frequency The Advanced IPS panel in the display is quite stable, but the LEDs in all backlights dim gradually over time. As a general rule, you can expect a modern LED panel to dim by approximately 1% of its peak luminance for every 1000 hours of use. Because this display has both blue and red LEDs, the differential dimming of these LEDs can result in a slight color shift. For many uses, though, no color shift is perceived even after 2000 or more hours between calibrations.
Warm-up mode To facilitate a bulk calibration workflow where multiple monitors will be calibrated or recalibrated in a single session, the display includes a standalone warm-up mode. This mode allows you to warm up multiple monitors without connecting them to a host computer. The display is warmed up at the luminance specified in the active color preset. To enable standalone warm-up mode: 1.
– Custom color preset naming – Specification of custom color primaries and white point (in CIE xy or CIE u'v') – Performing a customized validation pass post-calibration – Overwriting the factory calibration memory store – Archiving of calibrated LUTs to the USB flash drive The StudioCal XML schema provides additional functionality beyond calibration. For more information, see Using the StudioCal XML schema on page 71.
White point This menu provides the following standard white points: ● D65: The standard white point for most video productions as well as most computer graphics and design work. It can also be used for film production. ● D50: The standard white point for soft proofing and print production. It is warmer than the D65 white point. ● D55: The traditional white point for film projection. It is the white point of the light output of a film projector’s lamp house.
StudioCal XML calibration The StudioCal XML calibration method allows you to very precisely specify the calibration targets for a color preset and calibrate up to three calibration presets in a single calibration session. StudioCal XML is an extensible XML schema developed by HP for display calibration and modification. It was first introduced with the HP DreamColor Z27x G1 Studio Display and has been extended to support the additional capabilities of this display.
3. Select Calibration. 4. Select Set calibration schedule. You must set the internal clock to set a calibration schedule. 5. Select the amount of time between calibrations, and then select Next. 6. Choose the appropriate duration, and then select Next. 7. Choose the day of the week to perform the calibration, and then select Next. TIP: Although you can choose any day and time, HP recommends you choose a time when no one is using the display so that production is not interrupted. 8.
Accessing automatic calibration validation information You can request the measurement information from the last automatic calibration, which contains the RGB patterns and the XYZ values measured by the instrument. If a StudioCal XML file was installed and contains validation elements, it also includes the XYZ values measured post-calibration for the validation patterns requested. To download the data from the last calibration: 1. Insert a USB flash drive into one of the DreamColor USB ports.
Automatically warming up the display at start of the day The display can automatically warm itself up prior to the start of the day to ensure that it is ready for color critical work the moment the artist sits down at their desk. This option warms the display up for 30 minutes, which ensures the display accuracy to be under 1.0 ΔE 2000. For your reference, the following table shows the display accuracy, expressed as ΔE 2000, at different warmup times.
Klein Instruments K10 and K10-A colorimeters These are high-speed, very accurate lightweight devices that support either direct monitor contact or use in a darkened room as a distance unit. Configuration Klein K10 and K10-A instruments come from the factory pre calibrated with a display matrix stored as cal file 15. If you have an existing unit, HP strongly recommends that you send your instrument to Klein for recalibration.
Configuration These instruments contain a wide number of configuration options, all of which can be set using the touchscreen LCD interface on the back of the instrument. The following table lists the recommended configuration for each display. PR 655 PR 670 PR 680 PR 680L PR 730 PR 740 Minimum firmware version 3.12 3.14 3.14 3.14 3.10 3.14-74X Bandwidth 8 nm — — — 2 nm 2 nm Aperture — 1 deg 1 deg 1 deg 1 deg 0.
● The display may take up to ten seconds after instrument connection to display the first calibration menu. This is normal for this instrument. ● Black level (zero) calibration must be performed each time after the instrument is powered on. If calibrating multiple displays, Konica Minolta recommends that zero calibration be performed every hour, especially if calibrating to a low luminance target, such as 48 cd/m2.
Usage guidelines Please note the following tips and guidelines when using the X-Rite i1Display Pro with the display: ● The display may take up to five seconds after instrument connection to display the first calibration menu. This is normal for this instrument. ● This instrument should be used in direct connection mode with the counterweight adjusted to maintain the instrument position during calibration. ● HP recommends that calibration be conducted in a dimly lit environment.
4 Using the StudioCal XML schema StudioCal XML is an HP-designed XML schema that provides detailed control over the display calibration process. It contains elements and tags that allow you to specify calibration targets for up to three calibration presets, provide custom preset names, and define validation patterns to be measured. It also is used to upload and download calibration LUTs, install custom input names, markers, and user presets, and upload and download the entire display configuration.
Calibration element The StudioCal XML schema allows for up to three separate calibration presets to be specified. To support this, a calibration element is used to enclose the configuration information for each preset. This element also contains an entries tag that is used to specify the number of presets to be calibrated by the XML file. This tag supports integer values of one, two, or three.
Only preset numbers 0 through 7 are supported. Any other number will generate a syntax error. HP strongly recommends that the Native preset (preset num 7) be left as native. name: Specifies the name that is assigned to the preset. This name appears in the on-screen menus. Names can be up to 14 characters in length and may consist of alphanumeric (A–Za–z0–9) characters, a period (.) and a space. All other ASCII characters are converted to periods.
use_uv: (optional) Specifies whether CIE xy or CIE u’v’ values are provided for the primaries and white point. This attribute accepts the values “xy” or “uv”. If this optional attribute is omitted from the tag, xy values are assumed. external: This attribute is used in conjunction with the “external_primaries” tag to allow the use of nonsupported measurement instruments. Used as a flag, this attribute supports values of “TRUE” and “FALSE”.
This second example instructs the display to calibrate two presets, the first with BT.709 primaries, a D65 white point, and a BT.1886 gamma. The second will be calibrated with DCI-P3 primaries, a P3 white point, and a 2.6 gamma. It stores both calibrations in the factory memory location. PAGE 86709.ICC. Refer to your operating system and/or application documentation for information on where to store these ICC profiles on your computer and activate them. Optional calibration tags The following optional tags can be added to the core calibration tags to provide additional capabilities. These optional tags must be placed before the element; they cannot be nested inside it. None of these tags are required to be in a StudioCal XML file.
cr: Specifies the desired contrast ratio. When this tag is in the XML file, a 0 black level will be calculated using the the cr and wY values. The result is a calibration with a lower contrast ratio on-screen and a higher black level than would normally be the case. This tag must be placed before the element. Validation After calibration, the display can be instructed to measure a set of patterns and record the measurements in a text file on the flash drive that contains the StudioCal.
PAGE 89● #Primary Colors: Post-calibration measurements of 100% saturation primaries. ● #Secondary Colors: Post-calibration measurements of 100% saturation secondaries. ● #Target Primaries: The CIE xy values for the desired primaries and white point, and the white point luminance in cd/m2. ● #Calibrated Primaries: The CIE xy measurements for calibrated primaries and white point, and the white point luminance in cd/m2. ● #Calibrated Secondaries: The CIE xy measurements for the calibrated secondaries.
store: Specifies the memory store to be downloaded from and accepts the values “user” or “factory”. The display contains two different memory stores: factory and user. ● The factory store is a protected memory location where the factory calibration is stored. When a calibration is written to the factory memory location, the user memory location is also rewritten to match the factory memory location. This location can only be rewritten using StudioCal XML.
name: The name of the preset being created. Names can be up to 15 characters in length and may consist of alphanumeric (A–Za–z0–9) characters, a period (.), and a space. All other ASCII characters are converted to periods. folder: The name of the folder on the USB flash drive where the LUT files are stored. store: The memory store that will be used and accepts the values “user” or “factory”. The display contains two different memory stores: factory and user.
# PostLUT # # Begin Red # 0 1 … 16344 16383 #Begin Green # 0 1 … 16344 16383 #Begin Blue # 0 1 … 16344 16383 # END # name-num-PresetValue.xml: An XML file with the information to display in the Color space information onscreen menu and pass to the host computer from the EDID. This file is based on the StudioCal XML calibration schema, but uses the root element. A sample preset value file is shown below: PAGE 93● As only primary and white point measurements are made with the external instrument, a new luminance target cannot be iterated. Therefore, the existing luminance value for the preset you are recalibrating will be used. ● Existing calibration measurement data must be present on the display in order for gamma to be correctly calculated. In most cases, factory data or data from your most-recent calibration with a supported instrument will be sufficient. PAGE 94 When a USB drive is inserted into one of the DreamColor USB ports, the display reads the StudioCal file. You can generate a new color space based on the external measurements. The new color space preset is generated, and the display switches to that preset. With that color space active, you can use the test pattern generator to measure and verify the generated primaries.
Custom video input name example The following is an example of a StudioCal XML file showing the usage of the custom video input name elements. Custom markers Custom markers can be created via StudioCal XML. Custom markers can include up to 16 lines, and each line can have a unique color and line width.
Marker info parent element The details for each marker line is stored in two elements. Therefore a “marker_info” parent element is used to enclose the details for each marker line. This element does not include any tags and must be enclosed within a marker parent element. Marker position element startx: The line’s x axis starting point. Integer values between 1 and 2560 are supported. endx: The line’s x axis ending point. Integer values between 1 and 2560 are supported.
TIP: The optical disc included with the display has several pre-built custom markers for you to import into the display or use as a reference to build your own markers.
Display settings uploading and downloading Though Studio Cal XML is primarily designed for calibration-type functions, it is designed to provide additional non-calibration functionality. The tag allows you to export a display configuration to an XML file and then load that configuration back to the same display or deploy it to other displays. This tag was designed to facilitate the “configure, calibrate, and deploy” model used by many large VFX and animation studios.
5 Remote management The display provides three different methods for remote management: ● Web dashboard: Network-based one-to-one command and control ● WS-Management: IT-level network-based one-to-many manageability using SOAP protocols ● USB API: Host-based one-to-one command and control The WS-Management and USB API remote management methods are documented in separate documents and are available on the optical disc provided with the display and on www.hp.com.
