55LV77D

What the LG 55LV77D is built to do

The LG 55LV77D is a 55-inch LCD module designed to be tiled with other identical panels into one large display. Each module has a native resolution of 1,920 x 1,080 (Full HD) and a typical brightness of 700 cd/m². It uses IPS panel technology, which keeps the picture readable for viewers standing well off-axis, so a wall can be watched from a side corridor as well as from the front. LG has discontinued this model. This page is written for organisations that already run it, for buyers comparing it with newer walls, and for anyone who needs a replacement that matches an existing installation.

Bezels, orientation and colour matching

On a video wall, the bezel is the visible gap between panels, so it has a direct effect on the picture. The 55LV77D measures 2.25 mm on its left and top edges and 1.25 mm on its right and bottom edges. It can be installed in landscape or portrait. Its Video Wall Image Creation technology compensates for colour and brightness differences between panels, which helps a multi-panel wall keep a consistent white balance. A 60Hz refresh rate is listed for reducing motion blur and judder in fast-moving content.

Connections, control and content software

The panel accepts HDMI, DisplayPort, DVI, RGB, audio and USB inputs, and offers a DisplayPort output and an audio output. For room or building control it provides RS232C in and out, an RJ45 input and an IR receiver. It is not OPS compatible, but an external media player can be attached. Content is handled through SuperSign W, which builds regular matrix and irregular layouts, while SuperSign C covers control and monitoring.

Where it fits in Qatar

• Monitoring rooms at industrial and energy sites: a 3 x 3 or 2 x 2 wall in an operations room in the Industrial Area or Ras Laffan, showing process data and camera feeds to shift teams. Keep the room inside the 0°C to 40°C operating range, which in practice means air-conditioned.
• Lobbies and reception areas: a portrait stack beside the reception of a ministry or authority in Msheireb or Doha, showing bilingual visitor information. Portrait mounting uses the WM-P640V wall mount.
• Training and briefing rooms: a wall at a training centre in Education City or a meeting space in West Bay, where several panels together give a large shared view for a group of trainees.

Planning and ordering a replacement

Each monitor measures 1,213.4 x 684.2 x 88.5 mm and weighs 23 kg, or 30.5 kg packed in a 1,337 x 828 x 239 mm carton. The mount interface is 600 x 400 mm VESA. Power is 230 W typical and 290 W maximum per unit, with 130 W listed for Smart Energy Saving, and operating humidity is 10% to 80%. Listed safety approvals are UL, cUL, CB, TÜV and KC, and EMC approvals are FCC Class A, CE and KCC. Each box includes a remote controller, power cable, DP cable, IR receiver, RS-232C cable, tiling guide and screws. Wall mounts and frame kits are optional.

Start with a free site survey to check wall structure, cable routes and room temperature before drilling. Choose the WM-L640V for landscape or the WM-P640V for portrait, and add FK-55V10 (horizontal) or FK-55V20 (vertical) frame kits where needed. Because this model is discontinued, the right next step is to request a quote for a current equivalent or a compatible replacement. Send the unit count, orientation, room conditions and any existing mount details. SmartRooms Qatar supplies the equipment, delivers to all eight municipalities of Qatar, arranges professional installation and usually issues quotations within one working day. We accept purchase orders (LPOs) and government tenders, including Monaqasat, and any lead time is confirmed in the quotation.
