It suits reception areas, government service counters and school corridors in Doha, Lusail and Al Rayyan. Request a quote from SmartRooms Qatar.

What the LDH43-SAI400TL is built to do

The Dahua LDH43-SAI400TL is a 43-inch display for indoor walls that combines the screen, media player and touch layer in one unit. Instead of a separate media PC and extra cabling for each screen, its Android 11 system plays scheduled playlists directly, which keeps reception areas and waiting rooms tidy and easier to maintain. The unit is supplied with a wall-mount bracket and a remote control.

Picture and touch facts that matter on a busy wall

The panel offers 3840 × 2160 resolution, 500 cd/m² typical brightness, a 178° viewing angle horizontally and vertically, and 10-bit colour (8-bit with frame rate control, 1.07 billion colours). The data lists both IPS and VA panel types, with typical contrast of 1,200:1 for IPS and 4,000:1 for VA, so confirm which variant applies to your order in the quotation. A 25% haze surface treatment helps reduce glare, and the capacitive touchscreen supports 10 touch points.

Processor and memory: quad-core A55 at 1.92 GHz, 4 GB RAM
Storage: 32 GB onboard, with a TF card slot up to 128 GB
Video input: one HDMI 2.1 port supporting 4K at 60 Hz

Built-in player, storage and remote management

The player decodes H.265 and H.264 video up to 2160p, and VP9 up to 2160p at 60 fps. It plays mp4, avi, mov, mkv and wmv files. Programmes can run in several play modes, and the split-screen layout can be rearranged to place video, images and text in different zones. The device uses a browser-server (B/S) architecture, so managers can schedule content by time and location, generate operation reports and control units remotely from a unified platform.

Where it fits in Qatar

A government service centre in Msheireb could use a unit like this at a queue entrance to show service times and wayfinding, with portrait orientation suiting narrow corridors. A private school in Al Wakrah fitting out a corridor could schedule timetables and event notices by location, changing content automatically at the end of each period. A hotel lobby in West Bay or a clinic reception in Al Khor can run information on a schedule updated from one platform, without staff editing each screen by hand.

Planning the installation and the environment

The rated operating range is 0 °C to +40 °C, and the manufacturer advises avoiding direct sunlight. Summer temperatures in Qatar can exceed 45 °C, so mount the unit on an interior wall inside an air-conditioned building, away from windows, and confirm the exact spot with the SmartRooms Qatar team during the free site survey. Dimensions are 967.0 × 556.0 mm and 28.8 mm deep without the bracket (31.1 mm with it). Net weight is 17.5 kg, and the VESA pattern is 400 × 400 mm, so check wall strength and fixings before installation. Power is rated 100–240 VAC, 50/60 Hz, typically 100 W and 125 W at maximum, with standby at 0.5 W or below. Listed certifications are CE EMC, CE LVD, CE ERP and RED. Products are covered by the manufacturer's warranty.

Questions about LDH43-SAI400TL

What is the Dahua LDH43-SAI400TL designed for?

It is a 43-inch indoor wall-mounted digital signage display for advertising, wayfinding and information. Its built-in Android 11 player runs scheduled playlists without a separate media PC, so reception areas, waiting rooms and lobbies can be updated centrally. The unit suits organisations that need one wall screen that shows content and responds to touch.

Does the screen support touch, and how many touch points does it have?

Yes. The touchscreen uses capacitive technology and supports 10 touch points, so more than one visitor can interact with the display at the same time. The source data lists the touch response time as 8 ms or more. Touch functions depend on the application you run, so review the interactive content with the SmartRooms Qatar team before specifying the rollout.

How good is the picture quality for a meeting room or lobby display?

The panel offers 3840 × 2160 resolution, 500 cd/m² typical brightness, a 178° viewing angle and 10-bit colour with 1.07 billion colours. The data lists both IPS and VA panel types, with typical contrast of 1,200:1 for IPS and 4,000:1 for VA, so confirm which variant applies to your order in the quotation. The 25% haze surface treatment helps reduce glare.

Will it be bright enough for a reception near a window in Doha?

Typical brightness is 500 cd/m², which suits indoor reception areas with controlled lighting. The manufacturer advises keeping the unit out of direct sunlight, so choose a wall that does not face a large window or receive afternoon sun. If the entrance has strong natural light, the SmartRooms Qatar team can review the position during the free site survey before installation.

Can it be installed in an outdoor area, a car park or a shaded terrace?

No. This is an indoor wall-mounted model with an operating range of 0 °C to +40 °C and an operating humidity range of 10% to 85% RH, non-condensing. Qatar summers can exceed 45 °C, so the unit should sit inside an air-conditioned building rather than on a terrace, in a car park or at a semi-open entrance. Discuss the exact location with SmartRooms Qatar before requesting a quote.

What does the built-in player handle?

The unit runs Android 11 with a quad-core A55 CPU at 1.92 GHz, 4 GB RAM and 32 GB ROM. It decodes H.265 and H.264 up to 2160p, and VP9 up to 2160p at 60 fps, and plays mp4, avi, mov, mkv and wmv files. The split-screen layout can be rearranged to fit different content zones, and several play modes are supported.

Can we schedule and monitor several screens from one place?

Yes. The unit uses a B/S architecture, manages programmes by time and location, generates operation reports, and can be controlled remotely through a unified management platform. A bank with branches in West Bay and Al Sadd, for example, could push rate notices to every location from one office. The source data does not detail platform licensing, so ask for it in the quotation.

Which ports and connections are included?

The unit has one HDMI 2.1 input supporting 4K at 60 Hz, one RJ-45 Ethernet port (10/100/1,000 Mbps self-adaptive), and Wi-Fi supporting 802.11 b/g/n/a/ac/ax. It also has one USB 2.0 and one USB 3.0 Type A port, a TF card slot up to 128 GB, and a 3.5 mm audio output. Two 5 W built-in speakers are included. Wired Ethernet suits sites where network reliability matters most.

Is the power supply suitable for Qatar's mains electricity?

The unit is rated 100–240 VAC at 50/60 Hz, a range that covers Qatar's 240 V, 50 Hz supply. Typical consumption is 100 W, rising to 125 W at maximum, and standby consumption is 0.5 W or less. The source data does not list the plug type, so confirm the power cable and socket arrangement with the SmartRooms Qatar team when you request a quote.

How much space and wall strength does it need?

The unit measures 967.0 × 556.0 mm and is 28.8 mm deep without its bracket, or 31.1 mm with it. It weighs 17.5 kg net and 22.8 kg gross, and mounts to a 400 × 400 mm VESA pattern using the included wall-mount bracket. Confirm that the wall can carry the load and that installers can work safely at the chosen height. The free site survey from SmartRooms Qatar covers this check.

Can the screen run in portrait orientation for a queue or clinic display?

Yes, the display mode supports both landscape and portrait. A clinic reception in Al Khor or Al Wakrah could use portrait orientation beside a corridor to show queue numbers, department directions and appointment reminders, while a wider lobby would keep landscape. Confirm the mounting height and viewing direction on site before installation.

Can a school or government entity order several units through an LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. When a school fits out several corridors, each unit needs its own wall location, bracket and power point, so list the locations in your request. Quotations are usually issued within one working day.
