Functions and Features

New frameless design

The new frameless design forms an entirely flat seamless digital canvas allowing a completely homogeneous image across multiple unified screens. The huge digital surface creates an unhindered viewing experience for your audience with a minimal image interruption of just 0.9 mm per screen.

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.

Frame Comp Function

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 are required for the entire setup.

DisplayPort and LAN Control Daisy Chain

  • Just one cable each for video and control
  • Only two cables required for setup
  • Up to 100 displays can be daisy chained

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.

Advanced Heat Management

Without heat management, displays placed higher on a wall sustain more heat. However, NEC’s advanced heat management ensures uniform heat dissipation.

Auto TileMatrix and Auto ID Technology

Auto TileMatrix and ID features allow you to simply set up the size of the video wall on the first display, and then automatically scale the content through the remaining displays to set up the entire video wall (of up to 100 displays in a 10 × 10 matrix).

DisplayPort Multi-stream Function

Thanks to the multi-stream function of DisplayPort technology, multiple displays can be daisy chained and still be individually controlled. This also makes a 2 × 2 video wall with native Ultra High Definition 4K/2K (3,840 × 2,160) possible.

Intelligent Wireless Data Function

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 is especially useful on larger installations.

Human (motion) sensor and Advanced Auto Dimming

Human (motion) sensor and Advanced Auto Dimming

This 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.

Optional Dual Expansion Slots

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 fiexibility customers require.

  • *OPS is a standard established by Intel Corporation.

NaViSet Administrator 2

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.

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.

  • *NEC Display Wall Calibrator

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 a user’s site.
