55CT5WN-Z

What the LG 55CT5WN-Z is

The LG 55CT5WN-Z is a 55-inch all-in-one display for video meetings, part of the One:Quick Works series. It combines a 4K UHD touch panel, a camera, a microphone array, speakers and a Windows PC in one unit, so a meeting room can run video calls without a separate display, computer and codec. LG has discontinued this model. This page is written for organisations that already own one, buyers comparing it with newer options, and anyone looking for a replacement.

Panel, touch and camera

The screen is a 55-inch U-IPS panel at 3840x2160 with 450 nit brightness, a 1000:1 contrast ratio and 10-bit colour depth, which gives 1.07 billion colours. Touch is 10-point multi-touch, and one touch pen is supplied, so attendees can annotate and sketch ideas together on the Zoom Whiteboard tool. The camera has a 120-degree field of view, 4x ePTZ zoom and video framing, and its Auto Framing function follows people in the room. The manufacturer notes that camera output matches the HD 720p specification of the Zoom Rooms app, so set expectations for remote participants accordingly.

Computing, connectivity and audio

• Processor and storage: AMD Ryzen Embedded V1605B with AMD Radeon Vega graphics, 8GB RAM and a 128GB SSD.
• Software: Windows 10 IoT Enterprise with Zoom Rooms preloaded.
• Wireless: Wi-Fi 802.11ac 2x2 and Bluetooth 5.0.
• Inputs: two HDMI, one DisplayPort over USB Type-C, RJ45 LAN, two USB 3.1 Type-A and one USB Type-C.
• Output: DisplayPort out through USB Type-C (DP Alt Mode).
• Audio: ten-microphone array with beamforming, a 6m pickup range and two 10W speakers.

Where it fits in Qatar

A 55-inch screen suits small and medium rooms rather than lecture halls. Three typical settings are:

• A department meeting room at a university training centre in Education City, where a small team joins colleagues in Doha and abroad through Zoom Rooms.
• A project office in Lusail or The Pearl, where a shared huddle space needs a whiteboard and camera in one unit.
• A government office in Msheireb or a district office in Al Khor, where staff work in Arabic and English side by side and need a dedicated meeting display.

Heat is the main environmental limit. The operating range is 0°C to 40°C with 10% to 80% humidity. Summer temperatures in Qatar can exceed 45°C, so install the unit in an air-conditioned room, away from windows that take direct sun, and avoid entrances where doors open onto hot air.

What to plan before you order

Decide on mounting first. The panel can sit on a wall using a 300x300 VESA interface, or on a desk with the optional 2-pole stand ST-653TW, which is sold separately. The head weighs 26 kg and measures 1265 x 769.5 x 61.8 mm, so wall fixings should be checked on site before drilling. With the stand fitted, the overall size is 1265 x 815 x 290 mm. Typical power draw is 127W and maximum is 245W, with a rating of 72 BTU, which helps when sizing the room's cooling.

SmartRooms Qatar offers free site surveys, so we can check wall type, cable routes, power points and room cooling before installation. Quotations are usually issued within one working day. Schools, ministries and companies buying several units can order through a purchase order (LPO), and government tenders, including Monaqasat, are supported. Because this model is discontinued, request a quote for a current equivalent or compatible replacement and tell us the room size and number of units you need.
