iiyama ProLite 55-inch 4K UHD Digital Signage Display – LH5566UHSB-B1AG

The iiyama ProLite LH5566UHSB-B1AG is a 55-inch 4K UHD digital signage display with an 800 cd/m² VA panel, Android 14 and built-in WiFi. It suits retail, corporate, hospitality and restaurant spaces that run content 24/7 in landscape or portrait. Procure.ae supplies the LH5566UHSB-B1AG across the UAE.

The 3840 x 2160 VA panel delivers 800 cd/m² brightness, 5000:1 static contrast and a 6.5 ms response time, with viewing angles of 178 degrees horizontally and vertically. Android 14 runs on the display, so apps install directly on it. iiSignage² manages content remotely, iiControl handles device management and iiShare supports wireless presentation. FailOver switches to the next available input when the default source has no signal, and anti image retention is included.

The display takes two HDMI 2.0 inputs and a USB-C input with DisplayPort Alt mode and 15 W power delivery. It has RS-232C control input and two RS-232C outputs, plus an IR loop-through for controlling several displays from one source. It mounts on a 400 x 400 mm VESA pattern and supports landscape and portrait orientation. The IP5X front rating covers dust protection, and the design is fanless.
