4K UHD Picture Quality

By supporting native 3840 x 2160 resolution with HDR compatibility, 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 while 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.

Cisco Compatible Partner

The M491 features full compatibility with Cisco WebEx Kit products, which are professional video conferencing tools that have everything integrated into a single soundbar, including microphone(s), camera(s), the speaker, and the Video Conferencing Codec. This, combined with the M491, provides the ultimate conferencing solution.

Professional Modularity

The M491 provides everything you need for your digital signage applications while also offering the ability to enhance your screen through multiple integrated professional technologies. The M491 accepts Intel Smart Display Modules Large or Small, allowing for sleek all-in-one intelligence and interoperability in a small form factor. This allows for the flexible implementation of Intel processor-based products directly into the NEC M491 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 set-up.

The M491 also expands on the success of earlier display line-ups by allowing for the optional implementation of a Raspberry Pi Compute Module 4 directly into the display. The Raspberry Pi Compute Module 4 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.

Input Detect Functionality

This feature allows you to prioritize up to three inputs so that if a primary source goes down, the display will automatically switch to whatever source you have 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.

NaViSet Administrator 2 Software

This software is an all-in-one remote support solution that runs from a central location and provides monitoring, asset management, and control functionality of NEC display devices and Windows computers. It is ideal for multi-device installations over arrays as it allows for task management, reporting, and on-demand control options.
