Advanced Color Adjustment
The SpectraView Engine (SVE) is a custom color processor engine integrated in the monitor. It combines individual
characterization and calibration of the monitor during production together with temperature and time monitoring, to provide an
unparalleled level of color control, accuracy and stability.
Adjustable color uniformity correction is available, utilizing detailed individual factory screen measurements together with the
SVE to produce the best possible matching displays.
The SVE provides the utmost in versatility; from faster and more advanced color calibration, to the ability to accurately emulate
colorspaces such as Adobe®RGB and sRGB, to performing printer output emulations using ICC Profiles and internal 3D Look
Up Tables.
The SVE can operate in one of two modes: On or Off.
To enable or disable the SpectraView Engine using the remote control:
1. Using the remote control, press the MENU button.
2. Navigate to the [PICTURE] menu then to [SPECTRAVIEW ENGINE].
Use the + – buttons to navigate the OSD menu.
3. Highlight [ON] or [OFF] and press SET/POINT ZOOM to enable or disable the SpectraView Engine.
4. Press EXIT button to return to the main [PICTURE] menu.
Using the SpectraView Engine
When the SVE is on, the monitor’s internal processor will handle many of the color management features and the user color
controls allow a unique level of precision to be achieved. The white point is adjusted using a CIE x, y control and the grayscale
response of the display is calculated and managed by the monitor itself.
The SVE includes Uniformity Correction, where different levels of compensation can be selected to enable a trade-off between
the most uniform brightness and color vs. maximum brightness.
The SVE has five Picture Mode memories that can be individually configured and selected. Each individual Picture Mode can
store fully customized color settings. This allows you to quickly switch between different settings by just changing between
picture modes.
Using the SVE will also give access to other advanced functionality, such as the ability to emulate several modes of human color
vision deficiency as well as the ability to select the monitor’s output color gamut.
To change the settings in each SVE picture mode:
Presets have been configured with settings for general use as described in the “Preset Types” table next page. When choosing
a preset for the SVE picture mode, all of the settings are immediately adjusted to match the preset. Each setting can be
individually adjusted to customize as needed.
1. Using the remote control, press the MENU button.

Self calibration
This function updates the monitor’s internal SpectraView Engine color processor to use measurements taken using a supported
color sensor device. These measurements will become the reference for all color settings in the monitor.
When an NEC MDSVSENSOR 3 color sensor is connected to the monitor’s USB Service (2A) port, the monitor takes
measurements and is calibrated automatically. Place the color sensor at the center of the screen and follow the messages
shown.
Otherwise, if using a near-range colorimeter device, measurements must be taken manually with the device and the CIE Y/x/y
values individually entered via the OSD using the remote control. Y is in units of cd/m2.
Depending on the monitor usage and other factors, performing a Self Calibration at least once per year is recommended.
Reset calibration
This deletes the color measurement data created by the Self Calibration function and returns to the original factory internal
reference color measurement data. All Picture Modes will automatically be updated. If you are using NEC Display Wall
Calibrator, uniformity adjustment data is also deleted.
Validation
This can be used to determine if the Self Calibration operation should be performed.
It compares measurements taken of various color patches on the screen by the color sensor with the expected values calculated
by the SVE, which uses the current internal reference color measurement data. The result of this comparison is indicated as an
average color difference (dE) value. Larger values mean there is a larger difference between the measurements and the internal
reference. If the dE value is higher than 3.0, Self Calibration is recommended to update the internal reference color data.
The Self Calibration function must have been previously performed before this function is available on the OSD menu.
NOTE:• [Self calibration], [Validation] and [WHITE COPY] are not available if the input is [DISPLAYPORT1] then [DisplayPort
VERSION] is set [1.4].
• The date and time stamped results of the “Self calibration” and “Validation” functions are stored in the monitor
and can be read by software on your computer. Setting the [YEAR], [MONTH], [DAY] and [TIME] in [SYSTEM] ➙

Connecting Multiple Monitors
Monitors can be connected to each other, both communication and video connections, in multiple monitor installations. Chaining
the video connections together creates a video wall where a single image can be tiled across all displays. When connecting
multiple monitors to install a video wall, communication and video cable connections are necessary and their configuration must
be carefully considered. Please refer to the “Wiring Diagram” on page 27 for making communication and video connections.
The monitor settings for configuring a video wall in the OSD and Monitor Web page settings are under [PICTURE], [SYSTEM].
• [PICTURE-ADVANCED]-[AUTO TILE MATRIX] – automatically configures the multi-display settings when the communication
and video ports are chained together. This automatically sets the [MONITOR ID] and position of the monitors in the video
wall following the physical wiring between the monitors.
Input the number of monitors arranged horizontally and vertically on the master monitor. The following settings are set
automatically when you run the auto setup: OSD menu [H MONITORS], [V MONITORS], [POSITION], [DisplayPort
VERSION], [HDMI MODE], [VIDEO OUT SETTINGS] and Input signal.
NOTE:• [MONITOR ID] in [AUTO ID/IP SETTING] will be automatically executed.
• This function is released if [MOTION] in [SCREEN SAVER] is activated.
• If input is DisplayPort 4K (60Hz) 10bit, this function is disabled.
Example of installation via LAN:
H MONITORS 3
V MONITORS 3
Master monitor
