The M751-AVT3 75″ Class UHD 4K HDR Commercial Monitor from NEC is a professional, large-format display with a full metal chassis and an ATSC/NTSC tuner. This model is feature-rich for seamless integration into corporate environments while maintaining the commercial ruggedness necessary for restaurant, command and control, and leisure signage situations. Robust connectivity and enhanced daisy chain capabilities allow for easy deployment and distribution of video and control signals. Boasting 500 nits brightness, UHD 4K resolution, and HDR compatibility, the NEC M Series is ideal for a majority of high-end presentation applications.

Industrial-Strength, Premium-Grade Panel
A full metal mechanical 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 in order to maintain professional-level image output and allow for 24/7 operation.
Enhanced Daisy Chain Capabilities
The M751-AVT3 display contains 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 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 of a single source. On top of this, simultaneous output and signal conversion through dual daisy chain functionality can allow for immediate source switching if multiple displays are needed to be used at once. LAN daisy chain functionality can be used to tie displays together from a control perspective.
Spectraview Engine
The large-sized NEC M series panels contain professional color control through proprietary Spectraview Engine technology. Spectraview Engine allows for 6-axis color trim functionality of RGBCYM for hue, offset, and saturation adjustments. Also, it can allow for up to five different programmable picture modes to be saved and recalled when necessary. These picture modes can have individual CIE Color settings, intensity, gamma, and white point settings if desired.
Multi-Picture Mode
NEC MultiSync M series displays can support multiple simultaneous images at the same time, like picture-in-picture or picture-by-picture, 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 is being displayed.
NaViSet Administrator
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. Control your entire NEC ecosystem through this free optional asset management software. NaViSet Server Edition (NASE) expands on the extensive device management capabilities of NaViSet Administrator 2 by providing enterprise level display management such as, multi-user support with secured communications and logging, running as an on-premises server with remote access, a browser-based interface aimed at mobile devices for management on the go, REST API support for interfacing with other applications and management systems, and support for secure access to remote devices on other networks via the internet.
Intel SDM Compatible
The M751-AVT3 has an ATSC/NTSC tuner installed in the SDM-S slot.
Raspberry Pi Compatible
As another option, the M751-AVT3 allows for the implementation of a Raspberry Pi Compute Module 4 directly into each display. The Raspberry Pi Compute Module 4 offers gigabit network speeds, faster processing than previous versions, and true 4K support. This version also comes imaged with the 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 Raspberry Pi to qualified CMS partner platforms. This can all be done through the supplied NEC remote control or remotely through a web interface.
