A 4K wall display with its own Android player

The Dahua LDH43-SAI400L V1 is a 43-inch, 16:9 wall-mounted LCD signage display built for showing schedules, wayfinding, announcements and promotions without a separate media box. Its 3840 × 2160 panel uses DLED backlighting, with 500 cd/m² typical brightness and a 178-degree viewing angle both horizontally and vertically, so messages stay readable from the side of a corridor. Colour is shown at 10-bit (8-bit plus FRC), and the surface haze is listed at 2%.

Playback, storage and connections

An Android 11.0 system runs on a quad-core A55 processor at 1.92 GHz, with 4 GB of RAM and 32 GB of storage. The unit decodes H.265 and VP9 up to 2160p at 60 fps and H.264 up to 2160p at 30 fps, and it plays mp4, avi, mov, mkv and wmv files. Connections include one HDMI 2.1 input at 4K 60 Hz, one RJ-45 port for 10/100/1000 Mbps Ethernet, USB 2.0 and USB 3.0 Type A ports, and a TF card slot supporting up to 128 GB.

Remote management that scales across sites

The device works with a browser-based management platform, so administrators can schedule content by time and by location, review operation reports and push changes remotely. Program releases can pass through multi-level permission review, data sent to the platform is encrypted, and each terminal can be protected with its own password. The split-screen layouts can be adjusted freely, so one display can divide its area into zones for video, text and images.

Where it fits across Qatar

In a government ministry reception in West Bay, the screen can show visitor directions and service updates, with layouts changed through the Sunday to Thursday working week. A hotel lobby in The Pearl might rotate event listings and welcome messages, and the two 5 W speakers suit light background audio rather than large ballrooms. In a university building in Education City, one screen at a corridor junction can display room schedules, while the platform lets facilities staff update several floors from a single office.

Planning the installation and power

A wall-mount bracket is included, and the VESA pattern is 400 × 400 mm.
The panel measures 956.1 × 546.1 × 57.9 mm without bracket, weighing 10 kg net and 15 kg gross.
Choose an air-conditioned interior wall away from direct sunlight. The operating range is 0 °C to +40 °C, while Qatar summer temperatures can exceed 45 °C.
Power input is 100–240 VAC at 50/60 Hz, with 75 W typical and 120 W maximum consumption.
Certifications listed are CE EMC, CE LVD and CE ERP.

A free site survey before fixing is recommended to check wall construction and mounting height, and SmartRooms Qatar can arrange professional installation. Request a quote from SmartRooms Qatar for the LDH43-SAI400L V1, with delivery to all eight municipalities of Qatar. Quotations are usually issued within one working day, and purchase orders and government tenders, including Monaqasat, are accepted.

Questions about LDH43-SAI400L V1

Who is the LDH43-SAI400L V1 designed for?

It suits organisations that need a single wall-mounted screen for schedules, wayfinding, announcements or promotions in indoor spaces. It is a 43-inch, 16:9 display with its own Android 11.0 player, so it runs without a separate media box or PC. Typical sites include reception areas, corridors and waiting rooms in air-conditioned buildings across Qatar.

Does it need a separate media player or PC?

No. The built-in Android 11.0 system runs on a quad-core A55 processor at 1.92 GHz, with 4 GB RAM and 32 GB storage. Content can sit on that internal storage, on a USB drive, or on a TF card of up to 128 GB. Fewer boxes behind the screen means fewer cables to route during installation.

Would it suit a hotel lobby in The Pearl that rotates offers?

Yes, for rotating offers and event listings in a climate-controlled lobby. The screen supports freely adjustable split-screen layouts, and schedules can be set by time and location. The two 5 W built-in speakers suit light background audio rather than large ballrooms, so plan an external amplifier through the 3.5 mm output if announcements are needed.

Can it play 4K video files?

Yes. The panel is 3840 × 2160, and the decoder handles H.265 and VP9 up to 2160p at 60 fps, and H.264 up to 2160p at 30 fps. Playable file types include mp4, avi, mov, mkv and wmv. Test a specific file on the unit before rollout, since frame rates and codec settings vary between encoders.

Can it be placed in a sunny window area in Doha?

Not as a specification. The operating range is 0 °C to +40 °C, and the manufacturer says to avoid direct sunlight. Summer temperatures in Qatar can exceed 45 °C, so place it on an air-conditioned interior wall away from glazed frontages. Confirm the exact spot with the SmartRooms Qatar team before the quotation is issued.

How heavy is it and what does the wall need?

The net weight is 10 kg and the gross weight is 15 kg. The panel measures 956.1 × 546.1 × 57.9 mm without its bracket and mounts on a 400 × 400 mm VESA pattern, with a wall-mount bracket included. A clinic in Al Sadd, for example, should book a free site survey to check wall construction and mounting height before fixing.

Can I connect a laptop or an external media player?

Yes, through the single HDMI 2.1 input, which accepts 4K at 60 Hz. There is no video output, so the signal cannot be passed on to a second screen. Audio can go to external speakers through the 3.5 mm output, and the unit has an IR receiver for its remote control.

Does it support Wi-Fi or Bluetooth?

Wi-Fi is available only through an optional external module, and Bluetooth is not supported. The unit has one RJ-45 port for 10/100/1000 Mbps Ethernet, so a wired connection is the most reliable choice for remote management. Mention in your enquiry whether you need the Wi-Fi module, because it is not standard equipment.

How would a university in Education City manage several units?

Through a unified management platform based on B/S architecture. Administrators can schedule programmes by time and location, generate operation reports and control devices remotely. Multi-level permission review, encrypted data transmission and per-terminal password protection help keep changes controlled when several departments publish content to different floors.

Is the power supply compatible with Qatar mains?

The unit is rated 100–240 VAC at 50/60 Hz, which covers the 240 V supply used in Qatar. Power draw is 75 W typical and 120 W maximum, with standby consumption of 0.5 W or less. A power cord is included in the accessory set. Ask for the plug type to be confirmed in the quotation before ordering.

Could a school in Al Wakrah order several units for its corridors?

Yes. Schools and other organisations can order several units under one purchase order (LPO), and the quotation is usually issued within one working day. Professional installation and delivery to all eight municipalities are available. Central scheduling through the platform lets staff update announcements on every corridor screen from one office.

How do I request a quote and what payment options are available?

Send an enquiry to SmartRooms Qatar with the quantity, the sites and any mounting requirements. Quotations are usually issued within one working day. You can pay by bank transfer, cheque or purchase order, and government tenders, including those on Monaqasat, are welcome. Delivery timing is confirmed in the quotation.
