49SE3KB

What the 49SE3KB is and where it stands

The LG 49SE3KB belongs to the SE3K series of standard signage displays. It is a 49-inch panel with a 1,920 x 1,080 Full HD resolution and a 350 cd/m² brightness rating, built to show information in a fixed location rather than to serve as a meeting screen. LG has discontinued this model, so this page is written for organisations that already run one, buyers comparing it with newer signage, and anyone who needs a like-for-like replacement.

Display and mounting facts that matter

The panel works in landscape or portrait orientation, which suits a wide information screen or a vertical directory. The bezel measures 11.9 mm at the top, right and left and 18 mm at the bottom. The monitor body is 1,102.2 mm x 638.5 mm x 54 mm, with a thinnest section of 38.6 mm, and the head weighs 14.3 kg. It uses a 300 mm x 300 mm VESA mount pattern, so the wall fixing must suit that layout.

Control, content and connectivity

Inputs include one HDMI, one DVI, one analogue RGB, one audio input and two USB ports, but there is no DisplayPort. Control options are RS232C in and out, an RJ45 network port and an IR receiver, and the box includes a remote controller with two batteries. An embedded SuperSign player on the RJ45 interface transfers content and manages the screen over the network, and the source lists compatibility with SuperSign-w lite and SuperSign-c. The display does not accept an OPS module, but an external media player from the MP500 or MP700 range can be attached. Where no server is available, USB content scheduling lets staff load and time playlists from a USB device.

Where it fits across Qatar

A clinic waiting area in Al Sadd is a typical setting: a 49-inch screen can show queue numbers and directions to viewers a few metres away. In a private school in Al Wakrah, a corridor screen can display timetables and event notices in English and Arabic. A hotel lobby in West Bay or a serviced apartment in Msheireb may use a portrait-mounted panel beside the reception desk for guest information. Each scenario depends on the content you plan, which is why the layout should be settled before ordering.

Environment needs care. The manufacturer says the conformal coating on the circuit board guards against dust, iron powder, humidity and similar rough conditions. That is useful for a dusty industrial-area office, but the source does not give an operating temperature range for this model. Before installing where dust storms, long summer heat or direct sun through glass are expected, confirm the site with the SmartRooms Qatar team, and keep the screen away from direct sunlight because 350 cd/m² is modest for window-facing positions.

Planning the installation and choosing a replacement

• Measure the wall and confirm the 300 mm x 300 mm VESA pattern before choosing a bracket.
• Optional accessories include the ST-492T stand, LSW350B wall bracket and AM-B330S VESA adapter.
• Plan the media player early: MP500 or MP700 if you need one, because OPS is not supported.
• Map the network port and RS232C cabling before installation day.

SmartRooms Qatar offers free site surveys, so we can check the wall, sightlines and power route before any mount is fixed. Because LG has discontinued the 49SE3KB, we will also check whether a current equivalent or compatible replacement fits your existing accessories and software. Request a quote with your site, quantity and preferred orientation, and our team will respond with a proposal, usually within one working day.
