LG 55EH5C-S 55-inch Dual-View OLED Signage Display

Overview

The LG 55EH5C-S is a 55-inch OLED signage display with a Full HD 1,920 x 1,080 panel on both faces of one slim head, so one unit can show the same content in two directions or different content on each side. The head is 7.94 mm deep with a 2 mm off-bezel. Its 0°C to 40°C operating range points to indoor, air-conditioned use, which suits banks, hotels and schools in Qatar. Request a quote.

Two screens in one slim head

The LG 55EH5C-S is a 55-inch OLED signage display built around a Full HD panel with a 1,920 x 1,080 resolution. The head is 7.94 mm deep, rising to 8.94 mm at the edge, and weighs 21 kg, so it suits wall and ceiling positions where a bulky signage screen would be hard to hang. Because both sides belong to one head, a single unit can serve two areas at once, such as a corridor or a reception counter facing two rooms.

Switching between modes is simple. The remote controller lets you mirror the same content on both sides or swap the two sources with one button press. Staff can show a queue ticket or a menu to visitors on one side while keeping an internal schedule on the other.

Picture facts that matter on site

OLED pixels produce their own light and switch off completely to show black, which gives deep contrast in dimmer lobbies and meeting areas. The data lists brightness of 100 cd/m2 at an average picture level of 100% and 400 cd/m2 at 25%. Compare these figures with the lighting in the room before choosing a location. The wide viewing angle means people approaching from the side can still read the content, and the off-bezel measures 2 mm on all four sides.

Connections, media players and software

The panel offers HDMI, DisplayPort and DVI-D inputs, each listed as 1+1, plus an audio output and control through RS232C, RJ45 and an IR receiver. Two USB 2.0 and two USB 3.0 ports sit alongside. The display is compatible with OPS-type media players, and an external media player can be attached. The optional OPS Kit KT-OPSA lets you add a plug-in computer module. SuperSign-w lite and SuperSign-c are listed as compatible software.

Planning the head, signage box and power

The display is supplied as a head and a signage box measuring 470.1 x 402.8 x 75 mm. Two 3 m mini HDMI cables and two 3 m power harness cables connect the two parts, so measure the route between the head and the box before fixing anything. Mounting options are a stand kit, a wall mount kit, a fixed ceiling mount, a rotational ceiling mount and a signage box cover, all optional. Power input is 100-240V at 50/60Hz with built-in power. Typical consumption is 375 W, 3 W in DPM and 0.5 W when powered off. Safety certifications listed are UL, cUL, CB, TUV and KC, and EMC listings are FCC Class A, CE and KCC. A free site survey by SmartRooms Qatar can confirm the wall or ceiling load for the 21 kg head and the cable routing before installation.

Where it fits in Qatar

Bank branch in West Bay: a two-sided display between the queue area and the advisory desk, showing service information to customers on one side and staff notices on the other.
School corridor in Al Wakrah: a dual-view unit in a shared corridor, with content facing both classroom wings and the signage box concealed behind the wall.
Hotel lobby in Msheireb: a slim unit in an air-conditioned lobby, playing welcome and wayfinding content from a single head.

Keep the unit in air-conditioned indoor spaces. The operating range is 0°C to 40°C with 10% to 80% humidity, while Qatar summer temperatures can exceed 45°C outdoors. Confirm the room conditions with the SmartRooms Qatar team before you order, particularly near windows, entrances and semi-open walkways.

Questions about 55EH5C-S

What is the LG 55EH5C-S used for in Qatar?

It is a 55-inch OLED signage display that shows content on two sides from one head. A bank branch in West Bay might place it between a queue area and an advisory desk, showing customer information on one side and staff information on the other. Its 1,920 x 1,080 resolution suits informational content, menus and wayfinding viewed indoors at short to medium distances.

How does dual-screen swapping and mirroring work?

The included remote controller switches the two displays between mirroring and swapping. In mirroring mode both sides show the same content, which suits a reception desk visible from two directions. In swapping mode the two sources exchange sides at the press of a button, so staff can switch what each side shows quickly during a busy period.

How bright is the LG 55EH5C-S, and will it work in a sunlit area?

The data lists 100 cd/m2 at 100% average picture level and 400 cd/m2 at 25%. These figures describe the panel, not the ambient light, so compare them with the lighting in your room before choosing a location. The wide viewing angle and deep black levels keep content readable for people approaching from the side. For a sunlit atrium or a space with large windows, ask the SmartRooms Qatar team to review the position before ordering.

Can the LG 55EH5C-S be installed outdoors or near windows in Qatar?

The operating temperature range is 0°C to 40°C, with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so this is an indoor, air-conditioned product rather than an outdoor one. Keep it out of direct sunlight and away from open entrances, and confirm the room conditions with the SmartRooms Qatar team before ordering.

Which media players and software does it support?

The display is OPS-compatible, so an OPS slot can take a plug-in media module, and the optional OPS Kit KT-OPSA is listed for this purpose. An external media player can also be attached. The manufacturer lists SuperSign-w lite and SuperSign-c as compatible software. Confirm with the SmartRooms Qatar team which playback setup suits your content and network before ordering.

What inputs and control ports are included?

Video inputs are HDMI, DisplayPort and DVI-D, each listed as 1+1, and there is an audio output. Control options include RS232C, RJ45 and an IR receiver, with two USB 2.0 and two USB 3.0 ports. A phone-to-RS232C gender adapter is included, which helps when the display is linked to a central control system in a school or government building.

How is the LG 55EH5C-S installed?

It arrives as a head and a separate signage box. Two 3 m mini HDMI cables and two 3 m power harness cables connect the two parts, and a signage box mounting bracket is included. Optional kits cover a stand, a wall mount, a fixed ceiling mount, a rotational ceiling mount and a signage box cover. Measure the cable route first, because the 3 m cable length limits the distance between head and box.

How much does the head weigh and what space does it need?

The head weighs 21 kg and measures 1,227.6 x 702.7 mm, with a depth of 7.94 mm rising to 8.94 mm at the edge. The signage box measures 470.1 x 402.8 x 75 mm. Confirm that the wall or ceiling can carry 21 kg and that there is room behind the head for the box and cables. SmartRooms Qatar offers free site surveys, which is a practical step before fixing a unit of this size in a public corridor.

What power does it need, and how much does it consume?

The power input is 100-240V at 50/60Hz with built-in power, so the listed range covers Qatar's 240 V mains. Typical consumption is 375 W, with 3 W in DPM standby and 0.5 W when powered off. The data does not list plug types, so confirm the socket type on site with your electrical contractor before installation.

Which certifications does it carry?

Safety listings are UL, cUL, CB, TUV and KC. EMC listings are FCC Class A, CE and KCC. The source also lists ErP as Yes, with Energy Star marked as not applicable. For a government or public sector tender, share this certification list with the procurement team so the specification can be checked against the tender requirements.

Is this model suitable for a school corridor?

It can suit a school corridor in Al Wakrah where content needs to face two directions, such as a timetable on one side and event information on the other. The 55-inch size and 2 mm off-bezel work well at eye level in a shared space. Choose a wall or ceiling mount that suits the corridor, keep the unit in an air-conditioned building, and ask for a site survey to set the mounting height.

How do schools and government bodies order this display?

SmartRooms Qatar supplies the LG 55EH5C-S by quotation, usually issued within one working day. Public bodies can order by purchase order or LPO, and tender submissions, including through Monaqasat, are supported. Payment is by bank transfer, cheque or purchase order. Send the quantity, mounting choice and delivery location across Qatar, and the team will confirm lead times with the quotation.
