55-inch UHD touchscreen for signage

The LG 55TC3CG-H is a 55-inch commercial display built for interactive digital signage. It delivers 3840 x 2160 resolution at 350 nit brightness with an IPS panel for wide viewing angles. The integrated webOS 4.1 platform supports native content playback without an external media player. It targets venues needing reliable touch interaction across the full screen area.

VESA mount with HDMI USB Serial Ethernet

Installation uses standard VESA mounting and connects via HDMI, USB, Serial and Ethernet ports. The projected capacitive touch layer recognises up to 40 simultaneous touch points with no dead zones at corners or edges. Unlike infrared alternatives, it maintains accuracy across the entire surface. No driver installation is required for Windows 10, Windows 8.1 or Linux operating systems.

Continuous operation with IPS consistency

The IPS panel maintains colour and contrast stability during extended operating hours typical of signage deployments. Fanless edge-lit LED backlighting runs silently while sustaining 350 nit output. The webOS 4.1 system handles scheduled content loops and remote management tasks without performance drift. Touch responsiveness remains consistent across multi-user sessions throughout the day.

Questions about this item

How do I confirm the 55TC3CG-H is working correctly after installation?

Power on the display and verify the webOS 4.1 home screen appears at 3840 x 2160 resolution with 350 nit brightness, then test up to 40 simultaneous touch points across the full 55 inch surface including corners for instant response.

What comes in the box with the 55TC3CG-H and what must I source separately?

The display includes HDMI, USB and Serial-Ethernet interfaces for connectivity; cables, mounting hardware and any external media players for Windows 10, Windows 8.1 or Linux content must be purchased separately.

Which version of the 55TC3CG-H should I choose for my deployment?

The 55TC3CG-H is offered as a single 55 inch Ultra HD touchscreen model with 350 nit brightness, webOS 4.1 and multi-OS support, so selection depends on mounting orientation and content strategy rather than hardware variants.
