What the LG 55EF5G-L is

The LG 55EF5G-L is a 55-inch OLED signage display built as an open frame with a flexible screen that can be set to a curve. Every pixel emits its own light, so the panel needs no backlight and no liquid crystal layer. That structure gives deep blacks with no light bleed and a rated contrast ratio of 150,000:1, which makes dark brand films, night-time menus and high-contrast graphics stand out. The unit is slim, with a depth of 12.4 mm without its mounting hardware.

Image and panel facts that matter

Resolution and refresh: 1920 x 1080 (FHD) at 120 Hz, with 1 ms grey-to-grey response time.
Brightness: 150 nits at 100% average picture level and 400 nits at 25%. Compare the 25% figure with lobby light levels.
Colour: 120% of BT709 colour gamut and 10-bit depth, giving 1.07 billion colours.
Surface: 2H hard coating with typical reflectance of 1.2%, and a 178 x 178 degree viewing angle.
Operating hours: rated for 18 hours a day across seven days, for moving content only.

Curved layouts and tiling

The panel works in both portrait and landscape orientation and supports concave and convex curvature, so one screen can form part of a feature wall or a column. When tiled, the landscape off-bezel edges measure 0.6 mm at top and bottom and 6.7 mm at each side, which keeps the image close to continuous across the grid. The optional Curvature Calibrator lets installers adjust curvature on site when the layout changes during installation.

Control and content management

Units can be linked in a LAN daisy chain, which lets you control and monitor each display, send data and update firmware across the group through one connection. The display runs webOS 4.0 with 16GB of internal memory and supports local content scheduling, a group manager, fail-over, and synchronised playback for videowalls. Connectivity covers one HDMI input (HDCP 1.4), one DisplayPort input (HDCP 1.3), RS-232C, LAN, IR, two USB 2.0 Type A ports and audio output. It works with SuperSign CMS v3.0, SuperSign Control, SuperSign WB, SuperSign Media Editor and Signage 365 Care.

Where it fits in Qatar

In a passenger lounge near Hamad International Airport, a curved column of these panels can carry flight and wayfinding content in a space where the architecture matters as much as the message. In a shopping mall in West Bay, a convex feature wall in the atrium can draw attention from the upper floors. A corporate lobby in Msheireb can use a portrait pair beside the reception desk for visitor information, with content managed centrally from one office. A Lusail hotel may use the same curved format at its restaurant entrance.

Planning the installation

Plan for an air-conditioned room. The rated operating range is 0°C to 40°C and 10% to 80% humidity, and Qatar summer temperatures can exceed 45°C. Typical power use is 309 W and maximum 318 W; the built-in supply accepts 100-240 V at 50/60 Hz. Weigh the mount against the head weight: 5.8 kg in landscape, 7.0 kg in portrait, plus a 3.5 kg signage box. Check the wall structure, cable routes and power points during a free site survey. Professional installation is available, and quotations usually arrive within one working day. Request a quote for your layout, quantity and orientation, and SmartRooms Qatar will confirm the details with you.

Questions about 55EF5G-L

What is the LG 55EF5G-L used for?

It is a 55-inch OLED signage display for places where a striking screen has to stand out, such as a passenger lounge near Hamad International Airport, a hotel lobby in The Pearl or a shopping mall atrium in West Bay. The curved open frame and portrait or landscape orientation let designers shape the screen around the architecture, while the 150,000:1 contrast ratio keeps dark brand content sharp. Request a quote to discuss your layout.

How does OLED differ from LCD for signage?

OLED pixels produce their own light, so the panel does not need a backlight or a liquid crystal layer. That allows absolute black with no light bleed, which the 55EF5G-L rates at 150,000:1 contrast. The panel is also slim, with a depth of 12.4 mm without its mounting hardware, which helps when units sit close to walls. Ask the SmartRooms Qatar team whether OLED suits your content mix.

Can the 55EF5G-L run in portrait mode?

Yes. The manufacturer data lists both portrait and landscape operation. The portrait head weighs 7.0 kg compared with 5.8 kg in landscape, so plan the bracket for the orientation you choose. Portrait units suit vertical wayfinding panels along a corridor or beside lifts in an Education City building. Confirm orientation on your drawings before ordering a grid of units.

How small are the gaps when tiling several units?

With off-bezel edges, the landscape gap is 0.6 mm at top and bottom and 6.7 mm at each side, and the portrait figures are the same. The package includes six tiling set fixers and two flex bars for joining units. For a 2 x 2 video wall in a meeting area of a Lusail office, the site survey checks the wall structure and cable route before installation. Request a quote with your grid size.

Will the display cope with Qatar's summer heat?

The rated operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so the display should be installed in an air-conditioned space, not on an open terrace or an unconditioned entrance. The unit includes a fan and a temperature sensor, but these do not extend the rated range. Confirm room conditions during the free site survey.

What power does it need and what does it draw?

It has a built-in power supply rated for AC 100-240V at 50/60Hz, so the input range covers Qatar's 240 V mains. Typical consumption is 309 W and maximum is 318 W, with 3 W in DPM standby and 0.5 W when powered off. Plan socket positions and cable routes for each unit, and check the plug arrangement with the SmartRooms Qatar team before installation.

How do I manage several screens from one place?

Units can be daisy-chained over LAN, so you can control and monitor displays, send data and update firmware for the whole group through one connection. The software list includes SNMP, Wake on LAN, status mailing, auto set ID, Control Manager and Crestron Inside. For a school or government office running several screens, this keeps management in one place rather than at each display.

Which content software works with it?

The 55EF5G-L supports SuperSign CMS v3.0, SuperSign Control and Control+ (v1.7 and v1.9), SuperSign WB v3.7.15, SuperSign Media Editor v3.7 and Signage 365 Care v2.9. It runs webOS 4.0 and has 16GB of internal memory for content. Local content scheduling and an embedded group manager are built in. Confirm the software version your team uses before ordering.

How do inputs and ports connect to a laptop or media player?

The display has one HDMI input with HDCP 1.4 and one DisplayPort input with HDCP 1.3, both suited to a media player or PC. A LAN port, an RS-232C input and an IR input support control, and two USB 2.0 Type A ports support USB Plug and Play. Outputs include DisplayPort, audio, RS-232C with IR out and LAN, which allows units to be chained. Check that your source supports the HDCP version before connecting.

Does it support Arabic on-screen menus?

Yes. The on-screen display language list includes Arabic alongside English, French, German, Spanish and many others. This is useful for Qatari government offices and schools that work in Arabic and English side by side. The SmartRooms Qatar team can confirm the language and menu setup during commissioning.

What comes in the box?

The accessories include a remote controller with two batteries, a power cord, a quick start guide, an IR receiver, a regulation booklet, an RS-232C adapter, a 2 m DisplayPort cable, a 2 m LAN cable, a 1.5 m RS-232 cable, a 3 m LC cable, cable tape, screws, six tiling set fixers and two flex bars. The Curvature Calibrator is an optional extra and is not part of the basic kit. Request a quote to add it.

How should I plan a site survey and installation in Qatar?

Weigh the wall or frame before mounting: the landscape head weighs 5.8 kg, the portrait head 7.0 kg, and the signage box 3.5 kg. Landscape dimensions are 1224.9 x 696.2 x 38.0 mm with mounting parts. The free site survey covers wall structure, cable routes and air conditioning, which matters for a curved wall in a Msheireb lobby. Quotations usually arrive within one working day, and we accept purchase orders and LPOs.
