Masterfully Crafted for Impactful Messaging

Create pixel-perfect imagery with the high-end panel quality of the fully commercial NEC MA series large format display. By implementing premium features and focusing on creating impressionable digital signage experiences, the MA series gives customers an elite display option. With its one-of-a-kind wide color gamut commercial panel coupled with the proprietary SpectraView Engine capabilities, these displays offer more color capabilities than ever before. On top of that, these products allow customers modular capabilities to customize their product based on their needs and applications. The new series contains a full metal mechanical chassis, allowing for a more robust design necessary for commercial applications while maintaining the attractive aesthetics that allow the focus of onlookers to be on what matters – the message. Robust connectivity options allow customers to have up-to-date connectivity options while also allowing for enhanced daisy chain capabilities when tying displays together for video or control signal distribution. The NEC MA series boasts 500 cd/m² brightness, which is ideal for a majority of high-end digital signage applications in restaurants, command-and-control, retail, museums, and corporate environments when high-end and feature-rich displays are necessary to convey important messaging.

High-End 4K UHD Picture Quality

By supporting native 3840 x 2160 resolution with HDR compatibility across the entire MA series lineup, imagery and messaging can become more vivid and lifelike than ever before.

Full Commercial Build

The full metal chassis allows for the ruggedness needed for true commercial environments, while integrated carrying handles reduce the likelihood of damage during installation. On top of that, integrated temperature sensors and active cooling fans ensure that the display remains cool and at a constant brightness output in order to maintain professional level image output.

Wide Color Gamut Panel

The new MA series products contain fully commercial Wide Color Gamut panels allowing for a broader range of viewable colors when compared to a traditional commercial grade panel. This, coupled with NEC's SpectraView Engine technology, allows customers to have complete color control over their panel for industry-leading customization and control.

Enhanced Daisy Chain Capabilities

All MA series displays contain the ability to directly daisy chain both the HDMI and DisplayPort input signals. The DisplayPort daisy chain is enhanced due to DisplayPort 1.4 connectivity and HBR3 capabilities. This allows for Multi-Stream Transport capabilities that can drive up to four independent displays (depending on the video card driving the system) from a single DisplayPort source by multiplexing several video streams into a single stream and sending it to the display that then acts as a branch device to demultiplex the signals into the original streams. This allows for up to four independent content pieces to be driven off a single source – ideal for menu-board and retail applications.

Multi Picture Mode

NEC MultiSync MA series displays can support multiple simultaneous images through Multi Picture Mode. This, in conjunction with SpectraView Engine technology, can allow for each separate image to even have different defined color settings if necessary. This means that each part of the display can be optimized for the type of content that's being displayed.

Input Detect Functionality

This feature allows for the customer to prioritize up to three inputs, so that if a primary source goes down, the display will automatically switch to whatever the customer has prioritized next. The first detect option also allows for the display to automatically turn onto any source that plugs into it, allowing the display to wake on any synced signal.

Round-the-Clock Scheduler

This scheduler allows for advanced scheduling of monitor power up/down, increasing panel lifetime, reducing power consumption, and saving the time and expense of finding and purchasing a third-party scheduling solution.

Human Sensor

Upon sensing movement, this sensor allows for automatic adjustment to certain settings and features in the display, which can lead to targeted messaging for dual-purpose display in digital signage or presentation applications.

Cisco Compatible Partner

The optional Cisco WebEx Kit is a professional video conferencing tool that has everything integrated into a single soundbar, including microphone(s), camera(s), the speaker, and the video conferencing codec. This, combined with the large format NEC displays, provide the ultimate conferencing solution.

Professional Modularity

The MA series gives customers everything they need for their digital signage application while also offering the ability to enhance their screen through multiple integrated professional technologies. The MA Series accepts Intel Smart Display Modules Large or Small through clever mechanical and electrical design, allowing for sleek all-in-one intelligence and interoperability in a small form factor setting. This allows for the flexible implementation of Intel processor-based products directly into the display without having to deal with the hassles of mounting external devices and running video or audio cabling. Audio, video, control, and power signals are all internal from the Intel SDM through to the display, simplifying installations and allowing for clean and easy setup.

The MA series also expands on the success of earlier display lineups by allowing for the optional implementation of a Raspberry Pi Compute Module 4 directly into each display. The Raspberry Pi Compute Module 4 greatly outperforms previous versions by offering gigabit network speeds, faster CPU processing, and true 4K support. The new version also comes imaged with the new and user-friendly NEC Mediaplayer. Through an intuitive user-interface, the NEC Mediaplayer allows you to load, schedule, and edit playlists, access internal storage, access online media through an internal browser, or even image the RPi to qualified CMS partner platforms – all through the supplied NEC remote control or remotely through a web-interface.

NaViSet Administrator 2
