LCD MONITOR

Model: WD550D-M2  /  4K UHD  /  Android 11

Built for integrators who need a display that disappears into the enclosure and keeps working. The WD550D-M2 delivers 2,500 cd/m² across a 55-inch 4K panel with an auto light sensor that maintains consistent readability from a sunlit lobby to a dim server room — without manual intervention on your end.

WHERE THIS MONITOR
EARNS ITS PLACE

🏪
RETAIL KIOSKS & POS

Drop it into a freestanding kiosk chassis or checkout counter housing. The slim bezel and flexible mount options — wall, floor, ceiling — let the integrator's enclosure carry the brand identity without the monitor getting in the way.

🚉
TRANSIT & WAYFINDING

Airports, rail stations, and transit hubs expose displays to high ambient light and continuous operation. At 2,500 nits with a 50,000-hour lifespan, the WD550D-M2 handles shift-less 24/7 duty cycles without scheduling maintenance windows.

🏥
MEDICAL & CLINICAL

Non-touch configurations work inside equipment where certified touch overlays aren't needed. Wide operating temperature and full RoHS compliance satisfy procurement requirements in regulated environments across the EU and US.

🏭
INDUSTRIAL CONTROL

Sheet-metal housing tolerates vibration. Operating range from −10 °C to 50 °C covers unheated factory floors and outdoor machine enclosures. Feed signals over HDMI 2.0 or LVDS; RS-232 available for legacy control systems.

📢
SIGNAGE & DOOH

The built-in Android 11 CMS handles scheduling, looped playlists, live data feeds, and remote management over LAN/WiFi/4G — so your client's AV team can update content from a browser without touching the hardware.

🎰
GAMING & AMUSEMENT

High peak brightness eliminates screen wash-out in bright casino floors or arcade lighting. Fast 6 ms response keeps motion clean in interactive or video-heavy applications. Secure hardware dongle prevents unauthorized firmware changes.
