Promethean ActivPanel D-Series 55" Digital Signage Display
Description
The Promethean ActivPanel D-Series 55" is a purpose-built digital signage display for hallways, common areas and other high-traffic, non-classroom spaces. Unlike Promethean's ActivPanel education and ActivPanel LE/LX ranges, the D-Series is a non-interactive (non-touch) panel, designed purely for always-on messaging rather than touch collaboration. It runs a 55" 4K UHD (3840 x 2160) direct-LED TFT LCD panel at 350 cd/m2 typical brightness, with a 178-degree viewing angle, 1.07 billion colours and a fanless, 24/7-rated design behind a 3H-hardness, anti-glare surface. The panel is built around a quad-core ARM Cortex-A55 (1.8 GHz) processor running Android 13, with 4 GB RAM and 16 GB of internal storage, and ships with Radix VISO and Rise Vision pre-installed for centralised fleet management and content scheduling (both require a paid licence to activate; Rise Vision is US-only). Connectivity covers 2 x HDMI 2.1 (one with ARC), DisplayPort 1.2a, USB-C with 65 W power delivery, dual RS232, USB-A 3.0/2.0, optical SPDIF out, an OPS slot for an optional Windows compute module, Wi-Fi 5 and Wake-on-LAN. Built on a full-metal chassis with a steel backplate, the 55" model supports both portrait and landscape installation on a 400 x 400 mm VESA mount, and is backed by Promethean's standard warranty and support programme (terms vary by region).
