MultiSync 55-Inch Super Slim Public Display: X551S - Technologies Used

Advanced Cooling System

  • Prevents the likeliness of image retention and improves color uniformity.

Ambient Light Sensor

  • Automatically adjusts the backlight and power management depending on the ambient lighting brightness.

Built-In Expansion Slot

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

LED Edge-lit Display

  • Enables a mere 1.7” unit depth, creating installation opportunities in even the tightest of spaces

Open Pluggable Specification (OPS)

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

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.

Sealed Panel Design

  • Prevents contaminants like dust, grease or steam from damaging the panel.

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.


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