What this 49-inch display offers

The LG 49SE3KD is a 49-inch standard signage display with a 1,920 x 1,080 Full HD panel and a typical module brightness of 350 cd/m². It is built for menus, wayfinding, schedules and promotional loops in indoor spaces, and its listed specifications include no touch function. Its slim frame, with 11.9 mm side bezels and an 18 mm bottom bezel, lets several units sit close together on a wall with a tidy, even appearance. LG has discontinued this model, so the information below is written for organisations that already own one, buyers comparing it with newer options and anyone looking for a replacement.

Content playback and management without a server

The display can play and schedule content from a USB connection, so a small site can refresh its playlists without connecting to a media server. Larger networks can use the two software tools named in the specifications: SuperSign W for content management and SuperSign C for control and monitoring. The unit supports SNMP for network management and accepts a Wi-Fi USB dongle for content distribution. Control options include RS232C in and out, an RJ input, an IR receiver and USB. The model is not OPS compatible, but it can be paired with an external media player, and the listed options are the MP500 and MP700.

Environment, power and build quality in Qatar

The listed operating range is 0°C to 40°C with 10% to 80% humidity, while Qatar summer temperatures can exceed 45°C. For that reason the display should be installed indoors in air-conditioned spaces, away from direct sunlight and window glare. The circuit boards carry a conformal coating intended to protect against dust, iron powder and humidity, which helps in sites with fine dust. The built-in power supply accepts 100-240V at 50/60Hz, which covers the 240 V, 50 Hz mains used in Qatar. Typical consumption is 65 W, falling to 50 W with smart energy saving, and the unit is listed as Energy Star 7.0.

Where it fits in Qatar

Clinic waiting areas in Al Sadd: a single 49-inch screen showing queue numbers and health information, mounted on an inside wall away from entrance glass.
Office lobbies in West Bay or Msheireb: a row of displays for visitor directions and notices, where slim bezels keep the wall looking orderly.
Private school corridors in Al Wakrah: timetable and event loops scheduled from USB, with no server to maintain.

Planning the installation

The head weighs 14.3 kg and measures 1102.2 mm x 638.5 mm x 54 mm, with a thinnest part of 38.6 mm and a 300 x 300 VESA mounting pattern. Optional accessories include the LSW230B wall bracket, the ST-432T stand and the AM-B220S VESA adapter. Before a row of units goes up, SmartRooms Qatar offers free site surveys to check wall construction, cable routing and ventilation. Basic accessories include a remote controller with two batteries, a power cord, a quick start guide, an RGB cable, a regulation book, a phone-to-RS232C adapter and an IR receiver. Request a quote for this model or for a current equivalent, and availability will be confirmed with the quotation.

Questions about 49SE3KD

Is the LG 49SE3KD still available from the manufacturer?

No. LG has discontinued the 49SE3KD, so new units may not be available from the manufacturer. If you already own one, send SmartRooms Qatar your requirements for brightness, connectivity and wall space, and we will suggest the closest option. If you are starting a new project, request a quote for a current equivalent or a compatible replacement. Availability for any option is confirmed within the quotation.

Who is the 49SE3KD suited to in Qatar?

It suits indoor, air-conditioned spaces that need one 49-inch screen for scheduled information, such as a clinic waiting area in Al Sadd, a hotel lobby in West Bay or a corridor in a government office in Msheireb. Its 350 cd/m² typical brightness and Full HD resolution suit content viewed from a few metres away. The specifications list no touch input, so it is best suited to playback rather than interactive use. Request a quote and we will review the layout with you.

Can it play scheduled content without a PC or server?

Yes. The display plays and schedules content from a USB connection, and the listing states that no server connection is required. This suits a small clinic or school office that updates its playlists weekly. You prepare the content on a computer, copy it to a USB drive and load it onto the screen. For a network of several displays, the SuperSign W content management software named in the specifications is the option to consider.

Which software manages and monitors the screens?

The specifications name two tools: SuperSign W for content management and SuperSign C for control and monitoring. SuperSign W lets you build playlists and send them to several displays, while SuperSign C lets you check device status and control units remotely. Licensing and set-up requirements depend on the number of screens and the network you use, so confirm them with the SmartRooms Qatar team while preparing your quotation.

Can I connect an OPS computer or an external media player?

The panel is not OPS compatible, so an OPS computer cannot be fitted inside it. An external media player can be attached instead, and the listed options are the MP500 and MP700. This matters for a hotel or retailer that wants the player in a communications cabinet rather than a PC behind the screen. Tell us your content requirements when you request a quote so we can match the right player to your load.

How can I control it over a network or with a remote?

The unit supports SNMP for network management and accepts a Wi-Fi USB dongle for content distribution. Serial control uses RS232C in and out, and an RJ input, an IR receiver and a USB port are also listed. Video inputs include two HDMI, plus DVI-D and RGB. IT teams at a government office or school can manage screens from a central point, while facilities staff keep the supplied remote for on-site changes.

Will it run on Qatar's 240 V electrical supply?

Yes. The built-in power supply is rated 100-240V at 50/60Hz, so it operates on the 240 V, 50 Hz supply used in Qatar. The supplied power cord connects the unit to the outlet, but check that its plug suits the socket at your site before installation. Typical consumption is 65 W per unit, which helps your electrician plan circuit loading when several screens share one wall.

How much space and wall support do I need for mounting?

The head measures 1102.2 mm wide, 638.5 mm high and 54 mm deep, and weighs 14.3 kg. It uses a 300 x 300 VESA mounting pattern. In an office in Msheireb or a lobby in West Bay, check that the wall can carry the weight and that the 54 mm depth clears switches and cable trunking. SmartRooms Qatar offers free site surveys to check this before installation, and the LSW230B wall bracket and ST-432T stand are optional extras.

Can it be used in hot, sunny or dusty areas in Qatar?

Use it indoors only. The listed operating range is 0°C to 40°C with 10% to 80% humidity, and Qatar summer temperatures can exceed 45°C. Place the screen away from direct sunlight and window reflections, in an air-conditioned space with stable temperature. The conformal-coated circuit boards help resist dust and humidity, but they do not make the unit suitable for outdoor or unconditioned areas. We will confirm the exact location during the site survey.

How much power does it use, and does energy saving help?

Typical consumption is 65 W, and smart energy saving mode is listed at 50 W. The unit is listed as Energy Star 7.0. In a hotel reception in West Bay that runs for long hours every day, the difference across several screens adds up over a year. Request a quote for the number of units you plan, and the rated figures will be included with your quotation.

What comes in the box with the display?

The basic accessories are a remote controller with two batteries, a power cord, a quick start guide, an RGB cable, a regulation book, a phone-to-RS232C adapter and an IR receiver. Optional items are the ST-432T stand, a media player, the LSW230B wall bracket and the AM-B220S VESA adapter. Decide which optional items you need when you request a quote, so the bracket and stand match your wall and installation plan.

Can a school buy several units under one LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat. A school fitting out corridors or a waiting hall with several 49-inch displays can request one quotation covering all units, the mounting accessories and delivery to all eight municipalities of Qatar. Send the number of screens and their wall locations, and we will confirm availability within the quotation, since this model is discontinued.
