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.

Full specifications Datasheet Compare alternatives

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).

See the 55" on your wall, to scale

On a phone, point your camera at the wall and see the 55" there at its real size. On a computer, upload a photo of the wall (or scan the QR code to take one with your phone and it will appear here) and drag the display around it to scale.

Not sure 55" is the right size for the room? The screen size calculator shows how far a 55" display carries for presentations, touch work and video.
