Product information

Description

The LG 55UH7N-E is a 55" LED digital signage flat panel with 4K Ultra HD (3840 x 2160) resolution and IPS panel technology. Designed for continuous 24/7 operation in commercial environments, the display delivers high brightness (700 cd/m²) and an anti-glare coating that reduces reflections in bright lighting. The unit runs webOS on a high-performance SoC, supports Wi‑Fi connectivity, and includes built-in speakers and VESA mounting for flexible installation.

Advantages

The display offers four times the resolution of FHD for clear, detailed visuals and uses an anti-glare finish to improve legibility in well-lit areas. The integrated webOS platform with a powerful SoC enables multi-tasking without an external media player and supports app development and connections to external sensors and partner apps. Durability features such as conformal coating on the power board, IP5x protection, 30° tilt capability and Shock Monitoring enhance reliability in business settings. Slim bezels, concealed power inlets and simple cable management allow close-to-wall mounting and efficient space use, while optional bezel accessories enable conversion to an art frame. The model includes enhanced security (LG EKP and relevant certifications including ISO/IEC 15408 Common Criteria EAL2) and uses recycled materials in the back cover and partial packaging to support sustainability. SuperSign content management solutions are available for centralized content control.

Suitable for

  • Retail displays and in-store promotions

How to use

Mount the display using the appropriate VESA bracket and hide cables through the provided cable management. Connect power and network (wired or Wi‑Fi) and use the webOS interface to install or configure signage apps and SuperSign solutions. Upload or schedule content directly via webOS or through compatible SuperSign services. For installation close to the wall, use the slim bracket and route power to the hidden inlet so the display sits approximately 13 mm from the wall when supported by the correct bracket and accessories.

Usage recommendations

Install the display in a well-ventilated area and avoid exposure to excessive dust, salt spray or humidity. For continuous 24/7 operation, ensure regular content and system updates via webOS or SuperSign, and consider using the optional bezel accessories and a certified installer for wall-mounting to maintain warranty and safety standards.

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
