LG 55UL5Q-M

The LG 55UL5Q-M is a 55-inch 4K UHD commercial digital signage display engineered for demanding, round-the-clock deployments. Built on LG's webOS 6.1 smart signage platform, it enables standalone content management, scheduling, and remote control without an external media player. With 500 nits of brightness, a wide 178° viewing angle, and Direct LED backlighting, it delivers vivid, detailed imagery in retail stores, corporate lobbies, hospitality venues, healthcare facilities, and transport hubs. Its 10.8 mm even bezel, portrait and landscape flexibility, integrated brightness sensor, built-in Wi-Fi and Bluetooth, and certified security architecture make it a versatile and low-maintenance signage solution for integrators and end-users alike.

Superb 4K UHD Picture Quality

The 55UL5Q-M uses an ADS LCD panel at 3,840 × 2,160 resolution with Direct LED backlighting, delivering 500 nits of brightness and a 178° × 178° viewing angle. The 1,200:1 native contrast ratio and DCI 80% color gamut produce accurate, vivid colors across a wide range of content types. With just 1% surface haze, the screen stays clean and readable without heavy anti-glare processing that can soften fine detail. In practice this means advertisements, data dashboards, and video content all look sharp and engaging from virtually any viewing position in the room — an important advantage in lobbies, retail floors, or open-plan areas where viewers approach from multiple angles.

Built-In webOS 6.1 Smart Signage Platform

The integrated LG webOS 6.1 operating system turns the 55UL5Q-M into a fully self-contained signage player — no external box, no additional licensing for the OS itself. The platform supports local content scheduling, USB Plug & Play playback, Tile Mode for video-wall configurations, screen rotation, gapless playback, and Play via URL for cloud-hosted content. It is also compatible with LG SuperSign CMS, SuperSign Cloud, SuperSign Control+, and LG ConnectedCare. For the end-user this means fewer devices to manage, fewer failure points, and a consistent, intuitive interface for day-to-day content operations.

EPEAT Bronze certified · Energy Star compliant · 50,000-hour panel lifetime

True 24-7 Operation, 50,000-Hour Panel Life

The 55UL5Q-M is rated for 24 hours a day, 7 days a week continuous operation — a specification that separates it from consumer or prosumer displays that tolerate only 8-12 hours of daily use before reliability degrades. The panel is rated for a minimum of 50,000 hours of lifetime, which at full 24-7 duty equates to over 5.7 years of continuous runtime. LG also offers an optional extended warranty for up to 5 years total coverage. For end-users running transportation displays, hotel lobbies, retail video walls, or control rooms, this duty rating removes the risk of unplanned downtime caused by running an unsuitable panel beyond its design limits.

Even 10.8 mm Bezel — Portrait and Landscape Ready

The uniform 10.8 mm bezel runs identically on all four sides, giving the display a clean, professional appearance in both landscape and portrait orientation. This even-bezel design is particularly valuable when multiple screens are mounted in close proximity — the consistent frame prevents the visual imbalance that can make tiled or adjacent displays look mismatched. Portrait mode (supported up to 35°C ambient) suits digital menu boards, wayfinding columns, and narrow-format retail displays. The display also supports up to ±15° face-up and face-down tilt, making high-mount and under-counter installations viable without compromising viewing comfort.

Automatic Brightness Sensor for Energy Efficiency

A front-mounted ambient light sensor automatically adjusts screen brightness in response to changing lighting conditions in the room. In bright environments the display pushes to full output; in dimmer settings it reduces brightness, cutting power consumption without any manual intervention. At 70% Smart Energy Saving mode, typical power draw drops from 124 W to 86.8 W — a meaningful saving across a large deployment running 24-7. For the end-user, this means consistently comfortable viewing regardless of time of day or seasonal light changes, while also supporting compliance with energy management regulations such as ErP and Energy Star.

Enterprise Security with EKP and Common Criteria EAL2

LG's Enhanced Kernel Protection (EKP) technology shields the display's operating system from unauthorized modification and external threats at the kernel level — a layer of protection that standard commercial displays do not provide. This is validated by ISO/IEC 15408 Common Criteria EAL2 certification, an internationally recognized security benchmark. For deployments in healthcare, finance, government, or corporate environments where sensitive data or proprietary content is displayed, this certification provides documented evidence of security compliance — which can be a procurement requirement and a meaningful reassurance to end-users handling regulated or confidential content.

Flexible Remote Monitoring and CMS Integration

The 55UL5Q-M supports remote monitoring and control via LG's web-based Control Manager, accessible from any mobile device or PC on the network — including access to historical performance data. It integrates natively with the full LG SuperSign ecosystem (CMS, Cloud, Control+, WB) as well as LG ConnectedCare for proactive fault detection and remote service. Connectivity options include Gigabit Ethernet (RJ45), built-in Wi-Fi and Bluetooth, plus RS-232C for legacy control systems, and Crestron Connected and SNMP support for integration into broader AV and IT management platforms. This breadth of management options makes it straightforward to fit into an existing infrastructure without forcing a change in control architecture.
