Overview

A 55-inch portrait display, the Dahua LDV55-HAI400L-M uses an industrial-grade panel for up to 24 hours a day. It decodes 4K video, runs Android 11 with 4 GB RAM and 32 GB storage, and receives schedules from a central platform. Its 1,200:1 IPS panel and 178-degree viewing angles suit lobbies, corridors and wayfinding points in Doha offices, malls and clinics. Request a quote today.

What the portrait panel delivers

The LDV55-HAI400L-M pairs a 55-inch IPS panel with a 9:16 aspect ratio, so content runs top to bottom rather than side to side. Its 2160 × 3840 resolution gives 4K detail, the panel is rated at 500 cd/m² typical brightness, and its typical contrast is 1,200:1. Viewing angles of 178 degrees horizontally and vertically keep text readable for people approaching from the side of a lobby or corridor. The surface treatment has 1% haze, and the panel produces 10-bit colour using 8-bit plus FRC, which is about 1.07 billion colours.

Playback, scheduling and remote control

Android 11 runs on a quad-core A55 processor at 1.92 GHz, backed by 4 GB of RAM and 32 GB of storage. The internal decoder handles H.265 and VP9 up to 2160p, along with H.264 at 2160p, so most 4K media files play without an external player. A split-screen layout can be adjusted freely to suit different content zones. The device uses B/S architecture to schedule programmes by time and location, generate operation reports, and accept remote control from a central platform.

Where it fits in Qatar

Three situations suit a floor-standing portrait screen:

Clinic or hospital reception in Doha: wayfinding, queue numbers and health information in an air-conditioned lobby.
Bank or government service hall in West Bay or Msheireb: service guidance beside the entrance, with content changed on a timetable.
Retail frontage or mall corridor in Lusail: tall promotional loops that suit narrow walkways, with different messages at different times of day.

Planning power, space and climate

The unit measures 1900 mm × 741 mm × 460 mm and weighs 50.32 kg net, or 57.4 kg in its packaging, so plan the delivery route, lifting and floor position before installation day. A base, remote control and power cord are included. The power supply accepts 100–240 VAC at 50/60 Hz, which covers the 240 V, 50 Hz mains used in Qatar, with consumption of up to 120 W. The operating range is 0 °C to +40 °C and direct sunlight should be avoided, so place it indoors in an air-conditioned space away from glazed frontages, where outdoor summer temperatures can exceed 45 °C. The unit has no video output, and Wi-Fi requires an optional external module.

SmartRooms Qatar offers a free site survey for heavy floor-standing units, so the floor, socket and network point can be checked first. Send your floor plan and quantity to request a quote, and the SmartRooms Qatar team usually replies within one working day.

Questions about LDV55-HAI400L-M

Which sites in Qatar suit a 55-inch portrait display?

Portrait screens work well where visitors walk toward information, such as hospital and clinic reception areas in Doha, the entrance of a bank branch in West Bay, or a school corridor in Al Rayyan. The 9:16 layout suits wayfinding, queue numbers, service directories and short promotional loops. Because the unit stands on its included base, it fits a floor position rather than a wall, which helps where a landscape screen would not fit the space.

Can the LDV55-HAI400L-M run around the clock?

Yes, within set limits. The manufacturer describes the panel as industrial-grade and designed to work up to 24 hours a day. In Qatar that only holds when the unit sits in an air-conditioned room, because the stated operating range is 0 °C to +40 °C and direct sunlight should be avoided. For a reception screen that runs all day, plan airflow around the unit and confirm the installation space with the SmartRooms Qatar team before ordering.

Which video formats and resolutions does it decode?

The internal decoder handles H.265 HEVC up to 2160p at 60 fps, H.264 AVC up to 2160p at 30 fps and VP9 Profile 2 up to 2160p at 60 fps. It also decodes H.264 MVC, MPEG-4 and WMV/VC-1 up to 1080p. Supported container files include mp4, avi, mov, mkv and wmv, and the audio compression listed is MPEG-3, WMA and WAV. The TF card slot accepts cards up to 128 GB.

How are schedules and remote updates managed?

The device uses B/S architecture, so programmes can be scheduled by time and by location, and the unit generates operation reports. It is managed from a unified platform, which lets a facilities team update playlists across several screens from one place. A clinic network or a government service centre with several branches in Doha can change the message on each screen without visiting every site.

How do I connect a laptop, media box or Wi-Fi?

The input is one HDMI 2.1 port that supports 4K at 60 Hz, and there is no video output, so the signal cannot be passed on to a second display. Network connection is through a gigabit RJ-45 Ethernet port. Wi-Fi needs an optional external module, and Bluetooth is not fitted. A 200 × 200 × 100 mm space is reserved for a third-party media box or mini PC, and the unit also has USB 2.0 and USB 3.0 Type-A ports.

What temperature and humidity limits should the room meet?

The stated operating temperature is 0 °C to +40 °C, with 10% to 85% relative humidity, non-condensing, and direct sunlight should be avoided. Outdoor summer temperatures in Qatar can exceed 45 °C, so do not place the unit in a sun-exposed frontage or a semi-enclosed porch. If the planned spot is near a window or a loading door, ask the SmartRooms Qatar team to review it during the free site survey.

Will it run on Qatar's mains power?

The power supply is rated 100–240 VAC at 50/60 Hz, which covers the 240 V, 50 Hz mains used across Qatar. Maximum power consumption is 120 W, and standby consumption is 0.5 W or less. The unit has a built-in AC power socket. Confirm the plug type on the supplied power cord against the wall sockets at your site before ordering.

How much floor space and handling does it need?

Overall dimensions are 1900 mm × 741 mm × 460 mm, with a net weight of 50.32 kg and a gross weight of 57.4 kg in packaging. Because the unit weighs about 50 kg, plan for a two-person lift, a level and firm floor, and a doorway wide enough for the packed unit. The base is included, and a free site survey can confirm the route and position before installation.

Does SmartRooms Qatar deliver and install it?

Yes. SmartRooms Qatar supplies the Dahua LDV55-HAI400L-M, delivers to all eight municipalities of Qatar and provides professional installation. A free site survey can confirm the floor position, power socket location, network point and access route for a unit of this weight. Government and school buyers can issue a purchase order (LPO) or bid through a Monaqasat tender, and payment can be made by bank transfer, cheque or purchase order.

Which certifications does this model carry?

The manufacturer data lists CE EMC, CE LVD and CE ERP certifications for the LDV55-HAI400L-M. The CE EMC mark relates to electromagnetic compatibility, CE LVD to low-voltage electrical safety, and CE ERP to requirements for energy-related products. When preparing a tender or purchase file, list these certifications as they appear in the model data.

What comes in the box?

The package includes the 55-inch display with its base, a remote control, a power cord, the user's manual and legal and regulatory information. The metal casing is black on the frame and rear, and the unit has an IR receiver for the remote. Because the base is supplied, you do not need a separate stand for a floor position, but confirm the floor is level and firm before installation.
