LG 55UH7N-E ecrã de sinalização digital ecrã plano 139,7 cm (55 polegadas) LED Wi-Fi 700 cd/m² 4K Ultra HD preto processador integrado WebOS 24/7

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.

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.

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.
