Sharp PN-P556 – 55" 4K UHD Professional Display 24/7 USB-C
Product Overview
The Sharp PN-P556 is a 55-inch 4K UHD professional display engineered for commercial digital signage, corporate presentations, and high-availability information display applications requiring 24/7 operation, USB-C connectivity, and precise color management. With 700 cd/m2 brightness, a high-haze IPS panel, SpectraView Engine hardware color calibration, integrated USB-C with 65W Power Delivery, and a 5-year warranty, the PN-P556 is a premium 55-inch option for demanding commercial AV environments.
Product Description
The PN-P556 delivers 3840x2160 UHD on a 55-inch IPS edge-lit panel at 700 cd/m2 brightness with 1200:1 contrast ratio (local dimming capable) and 178-degree viewing angles. The high-haze surface reduces ambient light reflections in bright commercial environments. SpectraView Engine provides hardware-level color calibration supporting gamma adjustment from 0.5 to 4.0, color temperature range from 3000K to 15000K, and HDR modes including HLG and ST2084 PQ, sRGB, Rec.1886, and DICOM. The integrated USB-C input supports DisplayPort Alt Mode at 4K, 65W Power Delivery, and USB hub functionality for streamlined single-cable laptop and compute device connections. Two HDMI 2.0 and two DisplayPort 1.4 inputs with loopout support daisy-chain signal distribution. LAN daisy-chain passes RS-232C, TCP-IP, and IR control to multiple displays over a single cable. Failover input switching monitors primary sources and automatically transfers to backup. The display supports portrait and landscape operation and includes an open Intel SDM slot for optional compute modules. Thermal protection, internal temperature sensors, and fan-based cooling support 24/7 continuous operation.
