Recommended Use Safety Precautions and Maintenance FOR OPTIMUM PERFORMANCE, PLEASE NOTE THE FOLLOWING WHEN SETTING UP AND USING THE LCD COLOR MONITOR: About the Symbols To ensure safe and proper use of the product, this manual uses a number of symbols to prevent injury to you and others as well as damage to property. The symbols and their meanings are described below. Be sure to understand them thoroughly before reading this manual.
WARNING Do not place this product on a sloping or unstable cart, stand or table, as the monitor may fall, causing serious damage to the monitor. Do not insert objects of any kind into the cabinet slots, as they may touch dangerous voltage points, which can be harmful or fatal, or may cause electric shock, fire or equipment failure. Do not spill any liquids into the cabinet or use your monitor near water.
CAUTION Do not climb on the monitor or the table where the monitor is installed. Do not install the monitor on a wheeled table if the wheels on the table have not been properly locked. The monitor may fall causing damage to the monitor or personal injury. Do not touch LCD panel surface while transporting, mounting and setting. Applying pressure on the LCD panel can cause serious damage. If the monitor or glass breaks, do not come into contact with the liquid crystal that is inside the screen.
Image Persistence Image persistence occurs when a residual or “ghost” image of a previous image remains visible on the screen. Unlike CRT monitors, LCD monitors’ image persistence is not permanent, but a still image being displayed for a long period of time should be avoided. NOTE: As with all personal display devices, NEC DISPLAY SOLUTIONS recommends using a moving screen saver at regular intervals whenever the screen is idle, or turn off the monitor when not in use.
Ergonomics CORRECT PLACEMENT AND ADJUSTMENT OF THE MONITOR CAN REDUCE EYE, SHOULDER, AND NECK FATIGUE. CHECK THE FOLLOWING WHEN YOU POSITION THE MONITOR: To realize the maximum ergonomics benefits, we recommend the following: • For optimum performance of the monitor, allow 20 minutes for warming up. Avoid reproduction of still patterns on the monitor for long periods of time to avoid image persistence (after image effects).
Product Features Accurate color reproduction • SpectraView engine The sophisticated NEC exclusive color processing engine integrated into the display. It combines internal luminance, white point, ambient lighting, temperature and time monitoring, together with individual characterization and calibration of each display during production, to provide an unparalleled level of color control, uniformity, accuracy and stability.
• PbP / PiP (see page 33) Increases productivity by displaying multiple input sources simultaneously, either next to each other (Picture-by-Picture) or a small inset screen on a large main screen (Picture-in-Picture).

Changing the Picture Mode and Preset English Several picture modes are available for you to choose one that is most suitable for the type of content. Each picture mode includes [Luminance], [Black], [Gamma], [White], [Red], [Green], and [Blue] settings. You can change these settings in the [Picture mode] menu. To change the picture mode: 1. Touch the Menu key. 2. Navigate to the [Picture] menu then highlight the [Picture mode] function. 3. Touch the > key to cycle through the available picture modes. 4.
3. Touch the > key to cycle through the presets. Choose the [Preset] that is most suitable for the type of content that is shown or application usage. Each [Picture mode] includes [Luminance], [Black] (Black level), [Gamma], [White (K)](color temperature ), [White (x, y)] (White point CIE x, y), [Red] (Red Primary CIE x, y), [Green] (Green Primary CIE x, y), and [Blue] (Blue Primary CIE x, y), settings. You can change these settings in the [Picture mode] menu. 4.
Running Stand-alone calibration Updating the factory color data with measurements taken from a color sensor results in color related settings, shown on the OSD, closely matching measurements from the color sensor. In effect, the color sensor’s measurements become the new reference for all of the SVE’s internal color calculations. All color presets in the monitor automatically update to use the new reference. Requirements for Stand Alone Calibration: • NEC MDSVSENSOR3 color sensor.
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 MDSVSENSOR3 color sensor is connected to the monitor’s SENS/MEM port, the monitor takes measurements and is calibrated automatically. Place the color sensor at the center of the screen and follow the messages displayed.
Using the USB-C port functions • Video and audio delivered by DisplayPort Alt Mode at up to 4K60Hz RGB10bit resolution. • Connecting USB devices such as keyboards, mice and USB flash drives at speeds up to 5.0Gbps. • USB power delivery to charge the connected computer’s battery with/at up to 65W. USB-C Video / Audio Battery charge / USB hub NOTE: • • These functions can be used concurrently; however, the actual behavior depends on the connected computer port or cable.
USB hub Function • Default setting is [USB2.0]. To use [USB3.1], please see [USB data setting] on page 50.
