Name: LG 43SM5KC 43-inch 450 nits FHD Business Signage Display
Brand: LG
SKU: lg-43sm5kc
Availability: Discontinued

Overview

The LG 43SM5KC is a 43-inch FHD business signage display rated at 450 nits, and the manufacturer has discontinued this model. It runs in portrait or landscape, takes HDMI, DisplayPort and DVI-D inputs, and has a built-in power supply. Organisations in Qatar that already run it, or need a like-for-like replacement for indoor retail and office signage, should request a quote for a current equivalent or compatible replacement.

What this discontinued LG model is and who it suits

The LG 43SM5KC is a 43-inch Full HD signage display from the SM5K series, built for indoor retail and office use. LG has discontinued this model, so this page serves three groups: organisations that already run one and need matching units, buyers comparing it with newer signage, and anyone who needs a replacement that works the same way. SmartRooms Qatar can quote a current equivalent or a compatible replacement, and will check the mounting and input layout against your existing installation before you commit.

Panel, brightness and orientation

The 1,920 x 1,080 panel is rated at 450 nits. That suits interior walkways, shop interiors and reception areas lit by artificial light, but it is not a high-brightness outdoor unit. The screen runs in portrait or landscape, so one model can carry a tall menu board or a wide wayfinding screen. Side bezels measure 11.9 mm and the bottom bezel measures 18 mm, so units placed side by side show a narrow gap at the sides and a wider one along the bottom.

Connectivity, control and software

Inputs cover HDMI, DisplayPort, DVI-D, RGB, audio and an SD card slot. DisplayPort and audio are also listed as outputs. For control, the unit offers RS232C in and out, an RJ port, an IR receiver, a pixel sensor connection, USB 3.0 and the SD card slot. It is listed as compatible with SuperSign-w lite and SuperSign-c.

OPS compatible, with the optional OPS kit KT-OPSA
External media player attachable: MP500 or MP700
Optional HDBaseT extender EB-B100 for longer cable runs

Power, heat and planning for Qatar

The built-in power supply accepts 100-240V at 50/60Hz, which covers the 240 V, 50 Hz mains in Qatar. Typical consumption is 75 W, falling to 55 W in smart energy saving mode, and the unit carries Energy Star 7.0 certification. The panel has no power switch, so agree in advance how it will be switched on and off. The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summers often pass 45°C, so install the display only in air-conditioned rooms, not in outdoor enclosures, unconditioned kiosks or sun-exposed lobbies.

Typical fits include a shop in Msheireb showing portrait promotions beside the entrance, an office lobby in West Bay running landscape wayfinding, and a clinic reception in Al Rayyan where a wall-mounted screen sits within view of the waiting area. Each location should be checked for heat and sunlight before installation.

Mounting, accessories and what to send us

The head weighs 9.8 kg and measures 969.6 x 563.9 x 38.6 mm. It uses a 200 x 200 mm VESA interface. Optional accessories include the wall bracket LSW230B, the stand ST-432T and the VESA adapter AM-B220S. The box includes 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 a memory cover. Products are covered by the manufacturer's warranty.

Because the model is discontinued, check your existing mounting pattern and cable runs before ordering. SmartRooms Qatar offers free site surveys, and can confirm wall condition, load and cable routing in your building. Send us the model, the number of units and the location, and SmartRooms Qatar will return a quotation, usually within one working day, for a current equivalent or compatible replacement.

Questions about 43SM5KC

Is the LG 43SM5KC still sold by LG?

No. LG has discontinued the 43SM5KC, so new units may be hard to source through regular channels. SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches your screen size, mounting pattern and input needs. Share the location and the number of units you already run, and we will review the options with you before you commit to a purchase order.

What is the LG 43SM5KC used for in Qatar?

It suits indoor signage where a 43-inch Full HD screen fits the space: promotions in a retail unit in Msheireb, wayfinding in a Doha office lobby, or queue and information displays in a clinic waiting area in Al Rayyan. Its 450 nits and portrait or landscape support make it practical for these places, provided they are air-conditioned. Confirm the intended use with the SmartRooms Qatar team before ordering.

Can I mount it in portrait orientation for a menu board?

Yes. The panel runs in portrait or landscape, so one model can carry a tall menu board or a wide wayfinding screen. Before mounting a portrait unit, check that the wall or stand can carry the 9.8 kg head and suits the 969.6 x 563.9 x 38.6 mm body. Plan the cable route early so that the power and signal cables reach the unit neatly.

How bright is the screen, and can it sit near windows?

The panel is rated at 450 nits. That suits interior spaces lit by artificial light, such as shop interiors, reception areas and corridors. It is not a high-brightness outdoor model, so avoid positions where direct sunlight from a window or glazed storefront hits the screen, especially during Qatar's strong daytime light. Place it away from glare and check the position against your room's lighting before ordering.

What inputs and outputs does it have?

Inputs are HDMI, DisplayPort, DVI-D, RGB, audio and an SD card slot. Outputs are DisplayPort and audio, so a signal can be passed on from this unit. For control, it has RS232C in and out, an RJ port, an IR receiver, a pixel sensor connection and USB 3.0. Check which cable your source device needs, such as the included RGB cable, before ordering.

Does it support OPS or an external media player?

Yes on both counts. The unit is OPS-compatible, and the optional OPS kit KT-OPSA is listed as an accessory. It can also take an external media player, with the MP500 and MP700 named as compatible models. A media player lets you run content without a PC connected to the display, which suits menu boards and lobby loops in a Doha office or shop.

Which content software works with it?

The display is listed as compatible with two LG software packages, SuperSign-w lite and SuperSign-c. Choose the one that fits how your content team works and how many screens you plan to manage. The source data does not describe licensing terms, so ask for them in writing before you commit to a multi-screen rollout.

Can it run in a Qatar summer without air conditioning?

No. The operating range is 0°C to 40°C with 10% to 80% humidity, and Qatar summer temperatures often exceed 45°C. Install it only in air-conditioned rooms, not in outdoor areas, unventilated kiosks or sun-exposed lobbies. If your space gets hot at certain times of day, ask the SmartRooms Qatar team to review the location before the quotation and confirm that the room's cooling can hold 40°C or below.

Will it work on Qatar's 240 V mains?

The built-in power supply is rated 100-240V at 50/60Hz, so the 240 V, 50 Hz supply in Qatar falls within its range. The panel has no power switch, so plan how it will be switched on and off. The power cord is included, but confirm its plug type against the BS 1363 sockets in your building before you order, as the source data does not describe the plug.

How much power does it draw, and does it help with energy costs?

Typical consumption is 75 W, and smart energy saving mode reduces it to 55 W. The unit carries Energy Star 7.0 certification. For a school or office running several screens through a Sunday to Thursday working week, the lower figure matters when the displays stay on through business hours. Ask for a quotation that covers the full set of units and any accessories you need.

What wall mount or stand fits it?

The VESA mounting interface is 200 x 200 mm, and the head weighs 9.8 kg. Optional accessories include the wall bracket LSW230B, the stand ST-432T and the VESA adapter AM-B220S. Check the mounting pattern on your existing bracket before ordering, since a discontinued model may need a different pattern when replaced with a current equivalent.

Can I place two or more units side by side?

Yes, the bezels are narrow: 11.9 mm on the top, left and right, and 18 mm at the bottom. Two or more units side by side show a thin gap at the sides and a slightly larger one along the bottom edge. This layout suits a row of portrait screens or a simple display wall in a lobby, and you can review the arrangement with the SmartRooms Qatar team before installation.
