Sharp PN-LM551 – 55" AQUOS BOARD 4K Interactive Display 5-Year
Product Overview
The Sharp PN-LM551 is a 55-inch AQUOS BOARD interactive display with 4K UHD resolution, 20-point IR touch, a powerful Arm Cortex-A73/A53 octo-core processor, and USB-C single-cable connectivity, designed for collaborative workspaces, training rooms, and huddle spaces requiring a compact yet fully featured interactive flat panel with a 5-year warranty. The PN-LM series delivers 500 cd/m2 maximum brightness, 5000:1 contrast ratio, and pen-on-paper functionality with whiteboard and wireless capabilities built in.
Product Description
The PN-LM551 operates on a 55-inch TFT LCD with direct LED backlighting at 3840x2160 UHD. Brightness reaches 500 cd/m2 maximum (450 cd/m2 typical) with a 5000:1 contrast ratio, making it one of the brighter AQUOS BOARD models. The Arm Cortex-A73x4 2.3GHz plus Cortex-A53x4 2.0GHz octo-core SoC provides faster processing than the A55-based PN-LC series for demanding whiteboard and multi-application use. Three HDMI inputs plus USB-C (DP Alt Mode), RS-232C and LAN control, 10W x 2 stereo speakers, and a 5-year limited warranty complete the specification. The display supports landscape, portrait, and backward tilt orientation. Compatible accessories include the Shuttle PN-SPCi7W11A and PN-SPCi5W11A signage PCs and the AirServer ASC300 screen mirror solution.
