EdgeComp Provides for more even brightness distribution from center to edge during video wall configurations
TileMatrix Allows users to customize a video wall configuration using advanced On Screen Display controls.
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).
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.
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.
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.
