NEC UN552 Overview

The 55" LED Backlit Ultra-Narrow Bezel 3x3 Video Wall Bundle from NEC delivers an all-in-one solution that is suitable for digital signage, information display and command, and control applications. The TileMatrix, TileComp, and TileCut technologies combined with the ultra-narrow bezel design and the full adjustment capabilities of the Peerless DS-VW775 mount provide for a near seamless video wall without the need for additional third-party equipment.


Internal 14-bit programmable 3D lookup tables (LUTs) allow the display of 1.07 billion colors out of a palette of 4.3 trillion (with 10-bit DisplayPort input) for accurate color, smooth images, and hardware calibration.

Auto Tile Matrix

Auto Tile Matrix does auto setup of video wall via DP and LAN daisy chain.

Carbon Footprint Meter

Informs and motivates responsible use of the display by calculating and tracking the conservation of green gas emissions in real time.

LED Backlight

Provides for low power consumption and less hazardous materials.

Round-the-Clock Scheduler

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


Allows users to customize a video wall configuration using advanced On Screen Display controls.

Advanced Cooling System

Prevents the likeliness of image retention and improves color uniformity.

Built-In Expansion Slot

Allows for seamless integration of current and future NEC accessories and third-party components.

Raspberry Pi Compute Module Compatible

The Raspberry Pi Compute Module 3 NEC Edition computes power with signage displays for use in retail environments, passenger information, and quick service menu boards.


Automatically eliminates geometrical distortions between displays by adjusting for the width of the monitor bezels, working in tandem with TileMatrix on NEC displays.
