What the LG 43SE3KE is and why it is discontinued

The LG 43SE3KE is a 43-inch Full HD signage display from the SE3K series, built to show promotions, wayfinding, queue numbers and announcements in businesses that run screens for long hours. The manufacturer has discontinued this model, so this page is for organisations that already run it, buyers comparing it with newer signage, and anyone seeking a replacement that fits an existing installation.

Facts that matter for a signage deployment

The panel has a native resolution of 1,920 x 1,080 and typical brightness of 350 cd/m². Inputs include two HDMI ports, DVI-D, RGB, audio and USB, and external control runs through RS232C in and out, an RJ45 input and an IR input. The display is rated for 18 hours of operation a day, and stand-by mode keeps power-on status reachable over the network while the screen is off.

A USB drive loaded on one display can copy content to others, which saves setup time across multi-screen sites. The circuit boards carry a conformal coating against dust, humidity and iron powder.

Power: typical 55 W, maximum 90 W, 38.5 W in smart energy saving mode
Software: SuperSign CMS for content, SuperSign Control and Control+ for monitoring
Compatibility: OPS-type compatible, with MP500 and MP700 external media players listed
Certification: Crestron Connected, plus IEC 60950-1, UL 60950-1, FCC Class A, CE, KC and Energy Star 8.0

Where this size fits in Qatar

A 43-inch screen suits viewers standing or walking within a few metres. A private clinic in Al Sadd could use one in its waiting area for queue numbers and health tips, while a hotel lobby in West Bay could place one beside reception for guest information. A school corridor in Al Rayyan could carry timetable changes and event notices. Each location should be indoors and air-conditioned: the rated operating range is 0°C to 40°C with 10% to 80% humidity, and Qatar summers regularly exceed 45°C. Keep the unit out of sun-exposed atriums and covered outdoor walkways.

What to plan before ordering

The head measures 969.6 x 563.9 x 54 mm and weighs 10.0 kg; with the optional ST-432T stand it is 969.6 x 622.2 x 193 mm and 12.5 kg. The VESA mount is 200 x 200 mm, and the LSW230B wall bracket is an option. Bezels are 11.9 mm at the top and sides and 18 mm at the bottom, so side-by-side units show a visible frame; for an edge-to-edge wall, a narrower-bezel video wall product is the better choice. The built-in power supply accepts 100-240V, 50/60Hz, and each unit draws up to 90 W at maximum, which matters when planning circuits for several screens.

Questions about 43SE3KE

Has LG discontinued the 43SE3KE?

Yes. The manufacturer has discontinued this model, so new units built to the same specification may not be available. If you need to add a screen to an existing installation or replace a failed unit, send us your site details. SmartRooms Qatar will quote a current equivalent or a compatible replacement that works with your existing mount, player and control setup, with lead times estimated on the quotation based on stock.

What is the 43SE3KE designed for?

It is a 43-inch Full HD signage display for looping promotions, wayfinding, queue information and announcements. The series is rated for 18 hours of operation a day and uses a remote controller to build playlists and schedules. It suits clinic waiting areas in Al Sadd, hotel lobbies in West Bay and similar indoor spaces where content changes regularly. Touch input is only possible if you add the optional KT-T43E touch overlay.

What resolution and brightness does the panel offer?

The panel has a native resolution of 1,920 x 1,080 (Full HD) and typical brightness of 350 cd/m². These figures suit text, timetables and promotional loops viewed at normal signage distances. If the display would face a large window or strong daylight, check the lighting in the room before ordering, because typical brightness alone may not suit a bright atrium or a sunlit lobby.

Can I connect an external media player?

Yes. The 43SE3KE is listed as OPS-type compatible, and the MP500 and MP700 external media players can be attached. The display also has two HDMI inputs, DVI-D, RGB and USB for direct source connections. If your site uses a different player, SmartRooms Qatar can confirm whether it connects through HDMI or USB before you place an order.

Which software manages the content?

The series is listed with SuperSign CMS for content management and SuperSign Control and Control+ for control and monitoring. Simple playlists and schedules can be set from the remote controller, and a USB drive can carry content to other displays. If you manage screens at several sites across Doha, SuperSign CMS is the more practical route, and our team can advise on the setup at quotation stage.

Can it integrate with a boardroom control system?

Yes. It has RS232C in and out, an RJ45 input and an IR input for external control, and it is certified Crestron Connected for integration with professional AV controls. This suits a boardroom in West Bay where a single control panel switches sources and powers the display. Confirm the control protocol and cable pin-out with your AV integrator before ordering.

Can I control it over the network when the screen is off?

Yes. Stand-by screen mode keeps the power-on status controllable by network while the screen is off, which supports efficient power management. Typical consumption in smart energy saving mode is 38.5 W. The RJ45 input is listed under external control, and the optional Wi-Fi dongle AN-WF500 is an accessory, so confirm the connection method with your IT team before installation.

Is it suitable for a school corridor in Qatar?

A 43-inch panel suits a school corridor, reception or classroom door, where students read announcements at close range. A school in Al Rayyan could use the scheduling feature to show morning announcements and afternoon event notices automatically. The built-in 10W x 2 speakers can play audio, though many schools prefer to mute them in corridors. Request a quote to confirm mounting height, cable routes and the wall structure.

Can it be installed in a sunny or unair-conditioned area?

No, the rated operating temperature is 0°C to 40°C with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so install it only in an air-conditioned space, not in a sun-exposed atrium, a covered outdoor walkway or a room without reliable cooling. Keep vents clear and check the room cooling during a free site survey before installation.

How much power does it draw, and does it suit Qatar's supply?

The power supply is built in and rated 100-240V, 50/60Hz, which covers Qatar's 240 V, 50 Hz mains. Typical consumption is 55 W, with a maximum of 90 W and 38.5 W in smart energy saving mode. When you plan circuits for several screens, use the 90 W maximum per unit, plus any media player or control equipment connected to them. Confirm the socket type on site.

What are the size, weight and mounting requirements?

The head measures 969.6 x 563.9 x 54 mm and weighs 10.0 kg. With the optional ST-432T stand, it measures 969.6 x 622.2 x 193 mm and weighs 12.5 kg. The VESA mount is 200 x 200 mm, and the LSW230B wall bracket is available as an option. Before wall-mounting a unit, a free site survey can confirm that the wall or column can carry the load safely.

Can I build a video wall with it?

The bezel is 11.9 mm on the top and sides and 18 mm at the bottom, so visible gaps appear between units. It suits single-screen placements or grid layouts where a small frame is acceptable. For an edge-to-edge video wall with narrower bezels, a dedicated video wall product is the better choice, and SmartRooms Qatar can quote a layout suited to your space.

Should I buy this model or a newer one?

If you need matching units for an existing installation, the 43SE3KE is the reference point, so compare each replacement against its resolution, brightness, operating range, control options and software. If you are replacing a failed screen or building a new site, send us your mounting type, player, control system and room conditions. SmartRooms Qatar will prepare a quotation that shows the differences clearly.
