LG 55UN343H – 55-inch 4K UHD Hospitality TV

Product Overview

The LG 55UN343H is a 55-inch 4K UHD hospitality TV built for hotels and commercial properties that deploy many displays at once. The UN343H commercial series pairs a Direct-LED 4K panel with HDR10 and HLG support, so guest-facing content stays sharp, while commercial features such as USB cloning and Pro:Centric Direct support keep installation fast. With an ECI port and RS-232C control, this commercial LED hospitality display connects to LG set top boxes and room control systems. It is positioned as a value-focused 4K UHD commercial TV for high-volume guest room deployment.

Product Description

The UN343H series helps properties manage in-room TVs efficiently while supporting 4K Active HDR. USB data cloning copies configuration from one display to a USB drive and distributes it to additional units, which removes the need to set up each TV individually during a rollout. Public Display Mode and Lock Mode restrict settings and block non-compliant external input signals, protecting against misuse in public spaces. A 4K Upscaler converts Full HD sources to UHD through a multi-step process, and Multi IR addresses remote control signal interference between adjacent TVs. For Pro:Centric functionality and RF or IP content, an LG Commercial Set Top Box connects to the RS-232C port. The product images in this listing show the front-facing panel, the swivel commercial stand, and the rear connection layout. Three HDMI 2.0 inputs and an RF antenna input make this guest room commercial TV straightforward to integrate into existing hospitality distribution.

Frequently Asked Questions

How does USB cloning speed up a multi-room deployment?
Configuration from one TV is saved to a USB drive and applied to additional units, so installers avoid configuring each display individually. This reduces setup time for high-volume guest room rollouts.

Does the 55UN343H support Pro:Centric?
The TV supports Pro:Centric functionality when an LG Commercial Set Top Box is connected to the RS-232C port, which adds RF or IP content delivery and centralized features. Pro:Idiom is included for protected content.

How does it integrate with existing AV and control systems?
It provides three HDMI 2.0 inputs, an RF antenna input, RJ45 Ethernet, and RS-232C control, so it connects to set top boxes, distribution, and room control in a standard hospitality signal chain.

What features prevent misuse in public spaces?
Public Display Mode restores default settings as needed, Lock Mode blocks non-compliant external input signals, and Multi IR reduces remote interference between adjacent TVs.

What warranty and support are available?
The display is covered by LG commercial warranty terms. Contact Creation Networks for current coverage details, volume pricing, and integration support.
