Technologies

CableComp™

Equalizes the video signal to eliminate color halos on long cable runs.

Carbon Footprint Meter

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

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.

Open Pluggable Specification (OPS)

The first industry-wide standardization in option slots that allows for easier installation, use and maintenance of digital signage

Thermal Protection Panel

Starts with an extra thermal layer on the display panel to diffuse heat, followed by a fan-based technology specifically designed to work in both landscape and portrait modes and be controlled locally or remotely. Internal temperature sensors control self-protective circuits, while special self-diagnostics communicate the status of thermal characteristics.

TileMatrix™

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

Built-In Expansion Slot

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

Advanced Cooling System

Prevents the likeliness of image retention and improves color uniformity.

LED Edge-lit Display

Reduces overall depth while also lowering overall power consumption of the product’

TileComp™

Automatically eliminates geometrical distortions between displays by adjusting for the width of the monitor bezels, working in tandem with TileMatrix on NEC displays (some data on the screen will be lost in the area of the bezels).
