What the LDV43-SAI400L is built to do

The Dahua LDV43-SAI400L is a 43-inch indoor LCD display mounted in portrait orientation, designed for signage that runs around the clock. Its 9:16 panel and 2160 by 3840 resolution suit tall menus, wayfinding columns and vertical advertising, where a landscape screen wastes space. It runs Android 11 on a quad-core processor with 4 GB of RAM and 32 GB of storage, so content plays locally rather than depending on a constant connection.

Panel and playback performance

The IPS/VA panel offers 178-degree viewing angles both horizontally and vertically, so people walking past the side of a corridor can still read the screen. Typical brightness is 320 cd/m² with an 8 ms response time, which suits moving video and animated promotions under normal indoor lighting. The decoder handles H.265 and VP9 content up to 2160p at 60 frames per second, and the HDMI 2.1 input accepts 3840 × 2160 at 60 Hz from a media player or computer.

Management, scheduling and remote control

The device works within a browser/server (B/S) platform that schedules programs by time and location and produces operation reports, so one team can update several screens across multiple sites. Data sent to the platform is encrypted, program releases pass a multi-level permission review, and each terminal can be protected with its own password. The screen can also be controlled remotely from the platform, and an IR receiver is fitted for the supplied remote.

Where it fits in Qatar

A hotel lobby in West Bay or Lusail, with a column beside reception showing airport transfer times, event schedules and restaurant menus.
A university building in Education City directing students to lecture rooms, with timetables updated from a single office.
A clinic waiting area in Al Sadd showing queue information, department directions and health awareness messages.

What to plan before you order

The net weight is 41 kg and the gross weight is 51 kg. With the bracket fitted, the overall depth reaches 460 mm, so a fixed vertical mount needs at least two people to lift it. SmartRooms Qatar offers free site surveys to check wall or column load, cable routes to the network and power points, and clear space around the screen.

The rated operating temperature is 0 °C to +40 °C, and direct sunlight should be avoided. Install the unit in an air-conditioned indoor area away from windows and entrances. Power input is 100–240 VAC at 50/60 Hz, drawing 75 W typical and 80 W maximum. The built-in Ethernet port runs at 10/100/1,000 Mbps, while Wi-Fi requires an optional external module that should be specified at quotation.

The package includes the bracket, power cord, remote control and user manual. Request a quote from SmartRooms Qatar, and our team will confirm availability, the mounting requirements and the installation plan with your quotation, usually within one working day. Lead times are estimates confirmed with the quotation.

Questions about LDV43-SAI400L

Is the LDV43-SAI400L suitable for a hotel lobby in West Bay?

Yes, provided the screen sits in an air-conditioned lobby away from direct sun. Its 43-inch portrait display suits a column beside reception that shows airport transfer times, event schedules and restaurant menus. The 178-degree viewing angles let guests read it from the side, and the platform can update content across properties from a central office.

Can it be used for wayfinding in a university building in Education City?

It suits corridor wayfinding where students need room numbers, lecture schedules and campus notices, and vertical content fits narrow corridors well. Programs can be scheduled by time and location, so timetables can change between teaching periods and exam weeks without visiting each screen. Operation reports show whether each display ran as scheduled.

Would it suit a clinic waiting area in Al Sadd?

Yes, for queue information, department directions and health awareness messages in an air-conditioned waiting room. Its typical brightness of 320 cd/m² suits normal indoor lighting, and the rated operating humidity of 10 to 85 percent, non-condensing, covers standard clinic conditions. Avoid positions near entrance doors where hot air and direct sun reach the screen. Confirm placement during a site survey.

Could it run at a shopping mall entrance in Lusail?

Only indoors, in an air-conditioned area set back from glass frontages. The operating temperature is 0 °C to +40 °C with direct sunlight to be avoided, while Qatar summer temperatures outdoors regularly exceed 45 °C. A mall atrium with controlled air conditioning can work, but an exposed storefront or outdoor walkway cannot. SmartRooms Qatar can confirm the exact spot during a free site survey.

Can a government office order several units through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. A ministry visitor area could take several 43-inch portrait units running on the same platform. Request a quote listing the number of screens and locations, and the team will include the bracket and installation details.

What panel and resolution does the LDV43-SAI400L use?

It uses a 43-inch IPS/VA LCD with an ELED backlight, a 9:16 aspect ratio and 2160 by 3840 resolution, so portrait video fills the full height. Typical brightness is 320 cd/m², response time is 8 ms and viewing angle is 178 degrees horizontally and vertically. The surface has 25 percent haze, and colour depth is 10-bit (8-bit plus FRC).

Does it play 4K video, and which formats and storage does it support?

Yes. The quad-core processor decodes H.265 and VP9 up to 2160p at 60 fps and H.264 up to 2160p at 30 fps. The HDMI 2.1 input accepts 3840 × 2160 at 60 Hz. Storage is 32 GB with 4 GB of RAM, plus USB 2.0 and USB 3.0 ports and a TF card slot supporting up to 128 GB. Listed video formats include mp4, avi, mov, mkv and wmv.

Does it connect by cable or Wi-Fi?

The main connection is a 10/100/1,000 Mbps self-adaptive Ethernet port, which is the most reliable route for scheduled content and operation reports. Wi-Fi is available only through an optional external module, so specify it when you request the quote if no network cable can reach the screen. Plan the cable route during the site survey.

How are several screens managed from one office?

Through a unified platform built on B/S architecture, which schedules programs by time and location and produces operation reports. Program releases pass multi-level permission review, data sent to the platform is encrypted, and each terminal can have its own password. The platform can also control each screen remotely, so one team can manage displays across several sites.

Will it work with Qatar's mains electricity supply?

The power supply is rated 100 to 240 VAC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 75 W, maximum is 80 W and standby is 0.5 W or less. A power cord is included in the box. For a multi-screen project, add these figures to the electrical load plan before the installation day.

How heavy is it, and what does mounting involve?

Net weight is 41 kg and gross weight is 51 kg. A bracket is included for vertical mounting, which brings the overall size with bracket to 1,800 by 600 by 460 mm. Without the bracket the unit measures 1,749.4 by 592.6 by 92.3 mm. Two people should lift it, and a free site survey checks the wall or column strength before fixing.

Does it include speakers, a remote and a bracket?

Yes. The package lists a bracket, remote control, power cord, user manual and regulatory information. The unit has two built-in 5 W speakers and a 3.5 mm audio output for external sound systems, plus an IR receiver for the remote. Listed certifications are CE EMC, CE LVD and CE ERP, and the metal casing is black.
