LG 49SM3C (Discontinued) · Replacements in Qatar

Name: LG 49SM3C 49-inch FHD Standard Signage Display
Brand: LG
SKU: lg-49sm3c
Availability: Discontinued

Overview

The LG 49SM3C is a 49-inch FHD standard signage display rated at 350 nits, supporting portrait or landscape use. It has HDMI, DisplayPort and DVI-D inputs, RS232C and RJ45 control, and OPS and external media player support. The manufacturer has discontinued this model. Organisations in Qatar that already run it, or need a replacement for a lobby or meeting room, can request a quote for a current equivalent.

What the 49SM3C is and why it still matters

The LG 49SM3C is a 49-inch standard signage display from the SM3C series, with a 1,920 x 1,080 Full HD panel and 350 nits of brightness. LG has discontinued this model, so this page is written for three groups: organisations that already run it, buyers comparing it with newer signage, and anyone who needs a replacement for a similar installation. The screen suits corridors, reception areas and information boards where viewers stand at a moderate distance.

Orientation, brightness and frame

The panel supports both portrait and landscape orientation, so one model can show a tall menu or a wide timetable. The 350 nits rating suits well-lit indoor spaces. The published specifications do not cover direct sunlight, so a position facing glass needs checking on site. Overall dimensions are 1,102.2 x 638.5 x 38.6 mm and the head weighs 14.1 kg. Bezels measure 11.9 mm on the top, right and left and 18 mm at the bottom, which keeps the frame slim when several units sit side by side.

Connectivity, control and media player options

Inputs: HDMI, DisplayPort, DVI-D, RGB and audio in.
Outputs: DisplayPort, audio and external speaker out.
Control: RS232C, RJ45, IR receiver, pixel sensor, USB 3.0 and SD card.

The model is OPS-compatible and accepts an external media player, with the MP500 and MP700 listed. SuperSign-w lite and SuperSign-c are listed as compatible software for managing content. Optional accessories include the OPS kit KT-OPSA, the pixel sensor KT-SP0 and the HDBaseT module EB-B100. Confirm your source device and cabling with the SmartRooms Qatar team before requesting a quote, because compatibility depends on the chosen media player.

Where it fits in Qatar

A private school in Al Wakrah refreshing its corridors could mount the panel in portrait to show timetables and notices on a narrow wall. A hotel lobby in West Bay might use a landscape unit for arrivals, but only on an interior wall in an air-conditioned area, away from sunlit glass. A clinic in Msheireb could run queue and directions boards in its waiting area. The operating range is 0°C to 40°C with 10% to 80% humidity, and Qatar summers can exceed 45°C outside, so units should stay indoors and out of unconditioned spaces.

Planning the installation

Check that the wall or stand holds 14.1 kg plus the mount, using the 300 x 300 mm VESA pattern.
Choose a position within the stated temperature and humidity range.
Plan power: the built-in supply accepts 100-240V at 50/60Hz, and a power cord is included.
Compare the optional wall bracket LSW230B and stand ST-432T with the site.

SmartRooms Qatar offers free site surveys, professional installation and delivery to all eight municipalities of Qatar. Quotations are usually issued within one working day. Schools and government bodies can order through a purchase order (LPO) or a tender, including Monaqasat. Because this model is discontinued, request a quote for a current equivalent or a compatible replacement that matches your mounting and software needs.

Questions about 49SM3C

Is the LG 49SM3C still sold new?

No. LG has discontinued the 49SM3C, so SmartRooms Qatar quotes a current equivalent or a compatible replacement instead. If your organisation already runs this 49-inch display, send the model code 49SM3C-B.AMA with your site details and request a quote. The team will check which current model suits your mounting, cabling and software before quoting.

Is the 49SM3C suited to a Lusail office reception or meeting room?

It suits indoor reception areas, corridors and visitor-information boards, where a 49-inch screen is a comfortable size to read. In a meeting room it works best as a wall-mounted information or room-booking display rather than a main presentation screen. If the Lusail office has a bright glass frontage, arrange a site survey before choosing the mounting position.

Can the 49SM3C be mounted in portrait orientation?

Yes. The specifications list both portrait and landscape orientation, so the panel can run a tall menu board or a wide information screen. Choose the orientation before mounting, because the content layout must match it. For a portrait installation, check that the wall bracket or stand holds the 14.1 kg head securely at the chosen height.

What resolution and brightness does it offer?

The 49SM3C has a 1,920 x 1,080 Full HD panel with 350 nits of brightness on a 49-inch screen. Full HD suits text-heavy signage such as menus, timetables and room names at normal viewing distances. The 350 nits rating suits well-lit indoor spaces, so check the viewing position on site before ordering.

Does it support OPS or an external media player?

Yes on both counts. The model is listed as OPS-compatible, and the optional OPS kit KT-OPSA is available. It also accepts an external media player, with the MP500 and MP700 listed. A media player lets you run content without a computer attached to the panel, which helps in school corridors and hotel lobbies where a PC would otherwise be needed.

Which inputs, outputs and control ports are included?

Inputs are HDMI, DisplayPort, DVI-D, RGB and audio in. Outputs are DisplayPort, audio and an external speaker out. Control options include RS232C, RJ45, an IR receiver, a pixel sensor, USB 3.0 and an SD card slot. SuperSign-w lite and SuperSign-c are listed as compatible software. Confirm your source device and cabling with the team before requesting a quote.

Can it go in a hotel lobby in West Bay with windows facing the sun?

Be careful. The 49SM3C is rated for 0°C to 40°C and 10% to 80% humidity, and its published specifications do not cover direct sunlight. Place it on an interior wall away from glass that receives afternoon sun, inside an air-conditioned lobby. Qatar summer temperatures outside can exceed 45°C, and a sunlit position could push the panel beyond its rated range. A site survey will confirm the location first.

Will a clinic waiting area in Msheireb suit queue boards in portrait?

Yes, provided the waiting area is air-conditioned. Portrait mode lets a queue-number or directions board fit a narrow wall beside a corridor. Full HD resolution suits text-based queue information. If the clinic needs central control, the RS232C and RJ45 ports allow remote management. Ask the clinic's facilities team to confirm the room stays within 0°C to 40°C.

Can a school in Al Wakrah replace a corridor display using this model and its existing mount?

Compare the mounting first. The 49SM3C uses a 300 x 300 mm VESA pattern and its head weighs 14.1 kg. Optional items include the wall bracket LSW230B, the stand ST-432T and the VESA adapter AM-B220S. Because the model is discontinued, the team will also check whether a current replacement uses the same pattern. A free site survey confirms wall condition and mounting height before you order.

Does the power supply work with Qatar's 240 V, 50 Hz mains?

The built-in power supply is rated for 100-240V at 50/60Hz, which covers Qatar's 240 V, 50 Hz mains. A power cord is included in the box, and the power is built into the unit, so no external power brick is listed. Plan a dedicated outlet near the mount and a cable route from the signal source before installation. A site survey can check the socket position.

Which safety and EMC certifications does it carry?

The listing shows UL, cUL, CB, TUV and KC for safety, FCC Class A, CE and KCC for EMC, and Energy Star 7.0 for energy. The ErP entry is listed as NA. Buyers writing a tender specification can quote these marks directly from the manufacturer's data, and should check the label on the unit itself when it is delivered.

Can a school order several units on one LPO for a single site?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. Because this model is discontinued, a multi-unit order should be quoted as a current equivalent so that all panels match. Ask for one quotation covering every unit, the mounts and the installation.
