The 55" NEC UN551S utilizes S-IPS panel technology to provide a superior signage solution for building video walls. With excellent off-angle viewing and far less color shift than traditional video wall panels, this display is ideal for broadcast, retail and command and control applications. On top of that, 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. With these features, an even smaller area between neighboring displays and commercial brightness of 700 nits, this display clearly showcases NEC's vast experience in the video wall market.
