43SE3DD

What the 43SE3DD is and where it fits

The LG 43SE3DD is a 43-inch FHD (1,920 x 1,080) signage display with 300 nits typical brightness. It was built for announcements, wayfinding, menus and schedules in indoor spaces where a screen of this size is enough. The manufacturer has discontinued this model, so this page is aimed at organisations that already own units, buyers comparing it with newer displays, and anyone who needs a replacement that matches an existing setup.

Typical Qatar settings include a corridor in a private school in Al Rayyan showing timetables and events, a reception area at a clinic in Msheireb displaying queue and service information, and a ministry office in West Bay with a notice screen for visitors. These are sites where a 43-inch panel with USB scheduling and a built-in power supply is practical.

Connectivity and content scheduling without a server

The panel has two HDMI inputs, an analog RGB input, audio input, a USB port, an external speaker output, RS232C in and out, an RJ45 port and an IR receiver. The USB port lets you load and schedule content from a drive without a server connection, which suits a single screen that changes its messages daily. If the media player is disconnected, the display can show a preset image stored on USB instead of the no-signal image.

• External media player: MP500 or MP700 can be attached. OPS slots are not supported.
• Network: the optional AN-WF500 Wi-Fi USB dongle and SNMP support help with content distribution and network management.
• Software: SuperSign W for content management and SuperSign C for control and monitoring.

Built for dust, humidity and continuous use

Circuit boards carry a conformal coating designed to resist dust, iron powder and humidity. Operating temperature is 0°C to 40°C and operating humidity is 10% to 80%. Qatar summer temperatures regularly pass 45°C and dust storms are common, so install the display in an air-conditioned indoor space, away from direct sunlight through windows, and confirm the room conditions with the SmartRooms Qatar team before installation.

The power input is 100-240 V at 50/60 Hz with a built-in power supply, a range that covers Qatar's 240 V, 50 Hz mains. Typical consumption is 55 W, falling to 45 W in smart energy saving mode. The panel is listed as Energy Star 7.0.

Planning the mount, bezel and accessories

Monitor dimensions are 969.6 x 563.9 x 38.6 mm and the head weighs 9.6 kg. It uses a 200 x 200 mm VESA mounting pattern, and the optional LSW230B wall bracket and ST-432T stand are available. Bezels measure 11.9 mm on the top, left and right and 18 mm at the bottom, so a tiled wall will show a slightly wider gap along the bottom edge. Check wall construction and load before mounting; SmartRooms Qatar offers a free site survey.

The basic accessories are a remote controller with two batteries, a power cord, a quick start guide, an RGB cable, a regulation book and an IR receiver. Speakers (SP-5000), a VESA adapter (AM-B220S) and a touch overlay (KT-T430) are listed as optional.

Because this model is discontinued, the quickest route is to send us your current setup: the media player in use, the mounting, the number of screens and how content is updated. Request a quote and the SmartRooms Qatar team will recommend a current equivalent or compatible replacement, with quotations usually within one working day. Government buyers can issue an LPO or reference a tender with the request.
