The Dahua LDV55-PAI400L is a 55-inch vertical LCD digital signage display with 4K UHD resolution, 700 nits typical brightness and Android 11. It suits lobbies, retail entrances and wayfinding in offices, schools and venues, and is designed to run up to 24 hours a day. Procure.ae supplies it across the UAE.

The LDV55-PAI400L uses a 55-inch IPS/VA LCD panel with 3840 × 2160 (4K UHD) resolution in a 9:16 portrait layout. Brightness is 700 cd/m² typical, with a 178° viewing angle and an 8 ms response time. The manufacturer describes an industrial-grade panel designed to work up to 24 hours a day. The unit decodes H.265 HEVC and H.264 up to 2160p and runs a quad-core A55 processor at 1.92 GHz with 4 GB RAM and 32 GB storage. Two built-in 5 W speakers and a 3.5 mm audio output are included.

The unit runs Android 11 and uses B/S architecture, so programs can be scheduled by time and location, operation reports are generated, and the display can be controlled remotely from a unified platform. Connections include an HDMI 2.1 input at 4K 60 Hz, an RJ-45 Ethernet port, USB 2.0 and USB 3.0 ports, and an optional external Wi-Fi module. It installs vertically on its base. The 43-inch and 65-inch models in the Pro Series share these panel and software specifications.
