With just 0.9mm of inactive border around the edges, the NEC UN551S delivers a more consistent and seamless video wall. The 55in. displays feature professional-grade, S-IPS anti-glare panel technology that allows for less color shift and superior color uniformity, making them perfect for broadcasters, command and control, and retail customers. The UN551S also features a full commercial build with a steel chassis, commercial-grade cooling fans, and temperature sensors, along with direct-LED backlighting. These displays are designed for the rigors of 24/7 operation with advanced heat management capabilities in which internal temperature sensors automatically activate fan-based cooling if excess heat builds up within the unit. Other advanced technologies of this model include direct LED backlighting with localized dimming for improved brightness uniformity and higher dynamic contrast ratio. These displays are also capable of daisy-chaining UHD (3840 x 2160) resolution so that the entire video wall can be 4x that of FHD regardless of the size of the wall.
