LDV43-PAI400TL

A tall 4K panel built for round-the-clock use

The Dahua LDV43-PAI400TL is a 43-inch floor-standing display that runs in portrait orientation, the format used for menus, wayfinding boards, directories and queue information. Its panel carries a 2160 × 3840 resolution and a typical brightness of 700 cd/m², and the viewing angle is 178 degrees both horizontally and vertically, so visitors can read the screen from the side as well as straight on. The manufacturer describes the panel as industrial grade and rates the unit for operation of up to 24 hours a day, which matters in lobbies and waiting areas where a screen cannot be switched off during opening hours.

The screen is a 10-point capacitive touch display with a response time of 8 ms or less, and its surface treatment is rated at 1% haze. The casing is metal, black on the frame and rear, and the unit ships with a base, remote control, power cord, user manual and regulatory information.

Android playback, 4K decoding and flexible layouts

Inside the casing, an Android 11 system runs on a quad-core A55 processor at 1.92 GHz, with 4 GB of RAM and 32 GB of storage. This combination decodes H.265 content up to 2160p at 60 fps, H.264 up to 2160p at 30 fps and VP9 up to 2160p at 60 fps. Video files in mp4, avi, mov, mkv and wmv formats can be played, and the built-in split-screen function lets a content team arrange the page into separate zones, so one screen can show a video, a timetable and a notice panel at the same time.

The HDMI 2.1 input accepts 4K at 60 Hz from a media player or laptop, and a 3.5 mm audio output and two 5 W speakers handle sound. The unit has no video output, so it cannot pass the signal on to a second screen.

Managing content and devices across several sites

The device is designed around a browser-based management platform. Content can be scheduled by time and by location, programs can be released in several modes, and the system generates operation reports. Because the platform can control the unit remotely, a facilities team in Doha can update several screens from one place rather than visiting each site with a USB stick. The ports include one RJ-45 10/100/1000 Mbps self-adaptive Ethernet port, one USB 2.0 and one USB 3.0 Type-A port, and a TF card slot up to 128 GB. Wi-Fi is available only through an optional external module, and Bluetooth is not fitted.

Where it fits in Qatar and what to plan before installation

In a university building in Education City, a set of these units can guide students between faculties and show room bookings at entrances. In a bank branch in Msheireb, a unit beside the queue point can display service information and accept touch input from customers. In a shopping mall or hotel in West Bay, the portrait layout suits store directories and event listings. Each scenario shares the same planning needs.

Start with the environment. The operating range is 0 to +40 °C, and direct sunlight should be avoided. Outdoor temperatures in Qatar regularly pass 45 °C in summer, so place the unit indoors in an air-conditioned lobby, away from sun-facing windows and glass entrances, and confirm the exact spot with the SmartRooms Qatar team before ordering. Power is rated 100–240 VAC at 50/60 Hz, with a maximum draw of 200 W and standby below 0.5 W, which covers Qatar's 240 V, 50 Hz supply. Confirm that the supplied cord suits your BS 1363 socket. The overall size is 1800 x 625 x 460 mm and the net weight is 40.59 kg, so plan for at least two people to move it.

The operating humidity range is 10% to 85%, non-condensing. Before a visit, our team can run a free site survey covering the floor, power points and network port position, and quotations are usually issued within one working day. The unit carries CE EMC, CE LVD and CE ERP certifications.
