Brand: LG
SKU: lg-49sm5ke
Availability: Discontinued

Overview

The LG 49SM5KE is a 49-inch Full HD signage display rated at 450 cd/m² typical brightness, with a built-in webOS platform and embedded content management, so playlists can run without a separate PC. It has three HDMI inputs, DisplayPort, DVI-D, RS232C control and a 300 x 300 mm VESA mount. This model is discontinued by LG; SmartRooms Qatar can quote a current equivalent or compatible replacement in Qatar.

What the LG 49SM5KE is built to do

The LG 49SM5KE is a 49-inch standard signage display with a Full HD (1,920 x 1,080) panel and 450 cd/m² typical brightness. It suits dedicated screens in lobbies, corridors, waiting areas and back-office notice points, where a single display carries information for visitors or staff. The webOS platform and embedded content manager are built in, so your team can edit content and build playlists on the display without a separate PC beside each screen.

Playback, software and add-ons

A quad-core processor runs several tasks at once, so videos, images and HTML pages can play with gapless transitions and no black gap between items. The display streams content over RTSP, RTP, HLS and UDP Multicast, which helps when a central team sends live feeds to several screens. Up to two divided screens are possible in PBP or PIP layouts, in landscape or portrait, so one display can show a main message beside a secondary feed. It is compatible with SuperSign CMS, with SuperSign Control+ or SuperSign Control for monitoring and control.

Optional add-ons include a thermal printer connected over USB, an OPS kit, an external media player and the Signage 365 Care cloud service, which monitors display status and supports fault diagnosis and remote control.

Where it fits in Qatar

A private school in Al Wakrah could place one unit in a corridor to show timetables, events and announcements. In West Bay, a lobby with a glass frontage needs a site check first, because 450 cd/m² suits controlled indoor light more than strong direct sun. A bank branch in Doha can pair the display with a thermal printer on a USB connection to support a queue ticketing point.

What to plan before you order

Choose a mount: the 300 x 300 mm VESA interface, with the optional LSW350B wall bracket or ST-492T stand.
Keep the screen in an air-conditioned room, because Qatar summer temperatures often exceed 45°C, well above the 40°C operating limit.
Check the power cord plug against your sockets, as the source data does not specify the plug type.
Plan cable routes for three HDMI inputs and RS232C control if a control system is involved.
Book a free site survey before wall mounting, particularly for the 17.6 kg stand version.

Questions about 49SM5KE

Is the LG 49SM5KE still in production?

No. LG has discontinued the 49SM5KE, so this page is for organisations that already own the model, are comparing it with newer displays, or need a replacement. SmartRooms Qatar can quote a current equivalent or a compatible replacement. Send us your input needs, mounting method and installation room, and our team will match options to them before issuing a quotation.

Is a 49-inch model suitable for a school corridor in Al Wakrah?

Yes. A 49-inch screen suits a corridor, stairwell landing or small reception area, where it can show timetables, events and announcements at a comfortable viewing distance. For a large hall or lecture room, a bigger screen would be more practical. The unit supports landscape and portrait orientation and is managed through its built-in content tools, so staff do not need a dedicated PC beside it.

Will 450 cd/m² work for a lobby with windows in West Bay?

The typical brightness is 450 cd/m², which suits indoor areas with controlled lighting. If the screen faces a glass frontage that takes strong daylight, arrange a site survey before ordering so the position and lighting can be checked. The specification does not give a higher brightness figure, so we do not promise clear readability in direct sunlight.

Do I need a separate PC to run content?

No. The built-in webOS platform and embedded content management tools let you edit content and create playlists on the display itself, then play videos, images and HTML pages with gapless transitions. If your team manages several screens from one office, the display is compatible with SuperSign CMS, and SuperSign Control+ or SuperSign Control handle monitoring and control.

Which inputs and control ports are available for integration?

The display has three HDMI inputs, a DisplayPort input, a DVI-D input, a USB 3.0 input and an audio input, plus a DisplayPort (SST) output. Control options include RS232C in and out, an RJ45 connection and an IR receiver input. Check your control system's protocol and cable requirements with the SmartRooms Qatar team before ordering.

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

Yes on voltage. The built-in power supply is rated 100-240 V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply. Maximum consumption is 105 W. The source data does not state the plug type of the supplied power cord, so ask us to confirm it fits BS 1363 (Type G) sockets before delivery.

Can it go in an outdoor or unshaded area during summer?

No. The operating range is 0°C to 40°C with 10% to 80% humidity, while Qatar's summer temperatures often exceed 45°C. Install it only in air-conditioned indoor spaces. If the planned site is semi-open, such as a loading bay at a logistics yard in Mesaieed, tell our team before ordering so a suitable alternative can be confirmed.

Can it print queue tickets at a bank counter?

The display supports a thermal printer solution that connects through a USB port, and the manufacturer describes its use as a ticketing machine in places such as banks, restaurants and airports. The printer is not part of the basic accessory list, so specify it in your quotation. Confirm the printer model with the SmartRooms Qatar team before deciding how many counters to equip.

Can I mount it in portrait orientation?

Yes. The logo is detachable, which allows installation in landscape or portrait orientation, and the management interface offers portrait and long-range environment modes. For wall mounting, use the 300 x 300 mm VESA interface with the optional LSW350B wall bracket or VESA adapter AM-B330S. Decide the orientation before drilling, because a portrait layout changes cable routing.

What should a facilities manager plan before installation?

Plan for a head weight of 14.3 kg, or 17.6 kg with the optional stand, and a carton measuring 1,197 x 760 x 166 mm. Confirm the wall or stand position, the cable route and the nearest mains socket. SmartRooms Qatar offers a free site survey before wall mounting, which is worth booking for an office in Msheireb or Lusail where access to the fixing surface may be restricted. Installation can be included in your quotation.

Can I monitor several units remotely?

The optional Signage 365 Care service from LG is a cloud solution that remotely checks the status of displays at client sites, supports fault diagnosis and provides remote-control services. It suits organisations with screens spread across several Qatar locations, such as a hospital group with reception and waiting-area displays. It is not part of the standard package, so ask for it to be included in your quotation.

What comes in the box?

The basic package includes a remote controller with two batteries, a power cord, a quick start guide, an HDMI cable, a regulatory booklet, an RS232C adapter and a memory cover. The stand ST-492T, media player, wall bracket LSW350B, VESA adapter AM-B330S, OPS kit KT-OPSA, HDBaseT EB-B100 and touch overlay KT-T49E are optional. The product is covered by the manufacturer's warranty; we will confirm the terms with your quotation.
