LDV43-SAI400K

A 43-inch portrait display for floor-standing placements

The Dahua LDV43-SAI400K is a vertical LCD display built for standing installations in lobbies, corridors and reception areas. Its 9:16 panel runs in portrait orientation at 2160 × 3840 resolution, which suits wayfinding maps, building directories and tall promotional artwork that would look cramped on a landscape screen. The black metal casing ships with a base, so the unit can stand on the floor without custom fixing.

Panel and playback figures that matter on site

Typical brightness is 320 cd/m², with a 178-degree viewing angle both horizontally and vertically, so people approaching from the side can still read the content. Typical contrast is listed as 1,200:1 for the IPS type and 4,000:1 for the VA type. The backlight is ELED, and a 25% haze surface treatment softens reflections from nearby glass. Playback runs on Android 8.1 with a 1.6 GHz quad-core processor, 2 GB of RAM and 16 GB of storage. The decoder handles H.264 and H.265 video up to 4K, with listed limits such as 2-channel H.265 at 4K and 30 fps, and single-channel H.265 at 4K and 60 fps. These decoding figures come from single-file tests, so a multi-stream playlist should be checked before deployment.

Connectivity and remote management

Wired networking runs through a gigabit RJ-45 Ethernet port that negotiates 10/100/1000 Mbps automatically. An HDMI 1.4 input accepts 1080p at 60 Hz, two USB 2.0 Type-A ports and a TF card slot of up to 128 GB provide local media options, and a 3.5 mm audio jack is included. The HDMI, TF card and USB ports sit behind the back cover, which must be opened to reach them. Wi-Fi is an optional external module, while Bluetooth and video output are not provided. An infrared receiver responds to the supplied remote.

Management is built around a browser and server (B/S) architecture. Programs can be scheduled by time and by location, operation reports are generated, data transmission can be encrypted, and a program must pass multi-level approval before release. Terminals can be locked with passwords, and the unified platform can control each display remotely.

Where it fits across Qatar

• A hotel lobby in West Bay showing arrival information, dining hours and transport details, with the schedule changing through the day.
• A clinic reception in Al Sadd giving wayfinding to departments and visitor reminders, arranged in split-screen layouts.
• A shopping centre entrance in Lusail presenting promotions in portrait, with content rotated across several units managed from one platform.

The power supply accepts 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Maximum consumption is 80 W and standby draw is 0.5 W or less.

Planning the installation

The unit measures 1800 mm × 600 mm × 460 mm and weighs 41 kg net or 51 kg gross. Plan for two people to move it, and check ceiling height, door widths and lift dimensions before delivery. The operating range is 0 to +40 °C, with direct sunlight to be avoided. Qatar summers can push outdoor temperatures above 45 °C, so keep the display away from windows, outdoor entrances and sun-exposed atriums, in an air-conditioned interior. Storage range is -20 to +60 °C, and humidity should stay between 10% and 85% without condensation.

A free site survey from SmartRooms Qatar lets the team check floor space, socket positions, network points and sun exposure before the unit is delivered.
