The 55" NEC X555UNV utilizes S-IPS panel technology to provide a superior signage solution for building video walls. With excellent off-angle viewing & far less color shift than traditional video wall panels, this display is ideal for broadcast, retail & command & 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 enhanced brightness uniformity & 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, a 3.5mm bezel gap between neighboring displays & commercial brightness of 500 nits, this display clearly showcases NEC's vast experience in the video wall market.
