Multi Picture - This panel is used to manage the Picture-In-Picture (PIP) and Picture-By-Picture (PBP) settings, including the video input and Picture Mode used for the PIP function. Inputs - Controls how the video inputs on the display are configured.
| NEC MULTIPROFILER - USER’S GUIDE Display Configuration dialog ( Windows and Linux versions only) This Display Configuration dialog is accessed by clicking the configure button in the main MultiProfiler window. Display Configuration button (Windows and Linux versions only) opens the Display Configuration dialog, which is used to configure MultiProfiler if more than one monitor is used on the system, or to select between using DDC/CI and USB interfaces to communicate with the monitor .
| NEC MULTIPROFILER - USER’S GUIDE Picture Mode panel The Picture Mode panel controls the settings for the various Picture Modes that the monitor supports, and is also used for adjusting the Brightness and Black Level. The monitor supports 5 different configurable Picture Modes that can be quickly selected by clicking on the relevant buttons.
| NEC MULTIPROFILER - USER’S GUIDE Brightness The Brightness slider and spinbox controls adjust the monitor brightness. The brightness is indicated in Candelas per square meter (cd/m²) and represents an absolute value. The SpectraView Engine automatically calculates and compensates the brightness value as color settings such as white point are changed.
| NEC MULTIPROFILER - USER’S GUIDE Note: On the MultiSync PA231W, P232W, P242W, and X841UHD models, the Brightness and Black Level controls are shown as percentages instead of absolute luminance values. This is because these models do not have an internal luminance sensor and stabilization circuit. Black Level The Black Level slider and spinbox controls adjust the luminance of black on the screen and is set as an absolute value in Candelas per square meter (cd/m²).
| NEC MULTIPROFILER - USER’S GUIDE Metamerism correction Selecting the Metamerism correction setting can improve the white point color matching when the monitor is used side-by-side with a standard color gamut monitor. This feature compensates for the way the human eye perceives colors slightly differently compared to the scientific instrument used to adjust the monitor during calibration.
| NEC MULTIPROFILER - USER’S GUIDE Multi Picture panel The Multi Picture panel controls the settings for the Picture-In-Picture (PIP) and Picture-by-Picture (PBP) feature on the display. Note: The controls shown on this panel depend on the capabilities of the display model being used. For all models except the PA322UHD and X841UHD: The Multi Picture window feature allows: • Two different video inputs to be viewed simultaneously.
| NEC MULTIPROFILER - USER’S GUIDE Picture Mode selects the Picture Mode to be applied on the PIP window. The red arrow in the list indicates the current Picture Mode used on the main screen. This function makes it possible to view the PIP or PBP window in a different colorspace. Horizontal and Vertical Position - these controls adjust the location of the PIP window on the main screen.
| NEC MULTIPROFILER - USER’S GUIDE About Active Picture Note: Active Picture is available on the PA322UHD and X841UHD models only.

The controls in the Picture Mode panel, Color Vision panel, and the Multi Picture panel will impact only the currently selected picture window.
| NEC MULTIPROFILER - USER’S GUIDE Inputs panel The Inputs panel controls how the video inputs on the display are configured. Input Configuration allows multiple video inputs to be combined together to create one single UHD resolution image on the screen. This is useful in cases where for example the video source is not capable of outputting a single UHD resolution video signal, but can output several HD resolution signals.
| NEC MULTIPROFILER - USER’S GUIDE Color Vision panel The Color Vision panel controls the Color Vision Emulation settings used to emulate several modes of human color vision deficiency, also known as color blindness. This function can be used to help determine how people with such deficiencies will perceive colors.
| NEC MULTIPROFILER - USER’S GUIDE Settings panel The Settings panel controls some of the monitor and software features. The Power LED Indicator controls can be used to change the color of the LED between blue and green, and adjust the LED brightness if supported by the display. For example, the LED brightness can be reduced as necessary in dim environments if it is distracting. On the MultiSync X841UHD model the Power LED Indicator can only be turned on or off.
| NEC MULTIPROFILER - USER’S GUIDE About Digital Uniformity Correction Every LCD panel will have some form of color and luminance non-uniformity across the screen. Even though the panel used in the monitor has been carefully selected and sorted during production, there will be some remaining non-uniformity. To reduce the impact of this, each monitor is individually measured and characterized during production to map areas of non-uniformity.
| NEC MULTIPROFILER - USER’S GUIDE About DisplaySync Pro The NEC MultiSync P and PA Series displays feature an integrated USB hub with 3 downstream (outputs) and dual upstream (input) USB ports. Note: DisplaySync Pro is not available on the X841UHD model. The dual upstream USB ports allows the integrated USB hub to switch between two different host PCs. Devices connected to the USB outputs on the monitor will be switched between the two upstream ports.
