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 monitors 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 monitors 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.
2. Navigate to the [PICTURE] menu then to [PICTURE MODE].
Use the + – buttons to navigate the OSD menu. 
3. Press the + button to navigate to the [PICTURE MODE] field.
4. Select a setting from 1 through 5 at [PICTURE MODE].

White copy
This function can be used to “copy” the luminance and white point from another monitor when used in a multi-monitor
installation. This process is done by measuring the color of a monitor and setting those measured values into the monitor being
adjusted. This can be useful in situations where it is necessary to match a monitor in color to neighboring monitors without
having to recalibrate all monitors.
Before starting, it is necessary to input a full-white video signal to all of the monitors. Select the monitor that will be used as the
Target – or source - of the copy operation (A).
This function will measure the luminance and white point of the target monitor (A), and set these values to the current Picture
Mode of the destination monitor (B).
You can also fine-tune the measurement result while checking the screen color. If you want to return to the measured value,
select re-measurement.
The Self Calibration function must have been previously performed before this function is available on the OSD menu.

Monitor A – SOURCE monitor of white point to copy.
Monitor B – This monitor which performs a copy.

NOTE: When adjusting the color of multiple monitors, we recommend that you perform [SELF CALIBRATION] from
