Functions and Features
An Ultra Narrow Bezel
Mere millimetres separate content from display to display, which ensures a smooth transition across a video wall. The X555UNV minimizes that distance to a ground-breaking 3.5 mm.
DisplayPort and LAN Control Daisy Chain
Video signals and control signals can be daisy chained with one DisplayPort and LAN line respectively, meaning that just two cables manage everything for setup.
Auto TileMatrix and Auto ID Technology
Auto TileMatrix and ID features allow a user to simply set up the size of the video wall on the first display and automatically scale the content through the remaining displays, you can set up an entire video wall (of up to 100 displays in a 10 × 10 matrix).
Intelligent Wireless Data Function
The built-in near field communication (NFC) chip allows data to be read and written via a mobile phone or tablet PC. Users can significantly reduce installation costs as displays can be easily configured and serviced using the NEC NFC Android app. This is available even when the display is switched off and especially useful on larger installations.
Frame Comp Function
By synchronizing the content across the wall, this feature supports a seamless appearance and displays uninterrupted content to create one stunning image over all screens.
Advanced Heat Management
Monitoring and managing the temperature of each display is crucial to secure reliability and longevity. An industrial-strength, premium-grade panel with additional thermal protection, internal temperature sensors with self-diagnostics, and fan-based technology allows for 24/7 operation, and protects your display investment.
Without heat management, displays placed higher on a wall sustain more heat. However, NEC’s advanced heat management ensures uniform heat dissipation.
DisplayPort Multi-stream Function
Thanks to the multi-stream function of DisplayPort, multiple displays can be daisychained and still be individually controlled. This also makes a 2 × 2 video wall with native Ultra High Difinition 4K/2K (3,840 × 2,160) possible.
Human sensor and Advanced Auto Dimming
This new optional human (motion) sensor accessory (KT-RC2) helps to deliver creative digital signage to end users by allowing for dynamic control of brightness, audio and source inputs while saving operating costs. Auto dimming adjusts the backlight of the LCD automatically depending on the amount of ambient light.
Dedicated Colour Calibration Software
As the brightness and colour temperature of the LCD change with time, colours may not match across multiple screens. Our dedicated colour calibration software* ensures colour uniformity and fidelity across multiple screens, creating a perfectly matched image in tiled environments.

Optional Dual Expansion Slots
The dual slot technology allows for the integration of Open Pluggable Specification (OPS*) boards and other option slot products without the need to store additional external equipment. This offers the greater flexibility customers require.
NaViSet Administrator 2
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 the majority of NEC display devices and Windows computers. It is ideal for multi-device installations over larger infrastructures.
Proof of Play
This function provides accurate proof that displays are working as established and is helpful when checking on the status of the displays installed at user’s site.
