Planar LX55X-L 55"G3 Clarity Matrix 1920x1080 500 nit LCD video wall - 998-0139-00

Product Overview

The Planar LX55X-L is a 55-inch Clarity Matrix G3 landscape LCD video wall display engineered for mission-critical, 24/7 environments that demand outstanding visual performance at controlled ambient light levels. Rated at 500 nit brightness with a 1920x1080 Full HD resolution, the LX55X-L delivers a near-seamless tiled image with an industry-leading 1.7mm tiled bezel width. Part number 998-0139-00.

Product Description

The Planar Clarity Matrix G3 LX55X-L represents the third generation of Planar's acclaimed Clarity Matrix LCD video wall platform. Designed specifically for landscape orientation installations, this 55-inch panel integrates directly into the EasyAxis Mounting System for a finished depth of just 3.6 inches (91mm) — the thinnest profile available in this class. Off-board electronics architecture isolates the Video Controller (VC) and Remote Power Supply (RPS) from the display panel, minimizing thermal load on the screen and enabling hot-swappable n+1 redundant power supplies for continuous 24/7 operation without planned downtime.

The integrated Planar Big Picture Plus video wall processing engine supports 4K sources at up to 60Hz, scaling content across the full video wall canvas or any defined section. PiP (Picture-in-Picture), 4K quadview, and multi-source windowing are all handled on-board via the VC, reducing dependency on external processors. Leyard WallDirector software provides browser-based configuration, preset recall, and centralized health monitoring across all video wall components from a single interface.

Frequently Asked Questions

What is the difference between the LX55X-L and the LX55U-L-ERO?

Both are 55-inch G3 500 nit landscape panels. The LX55X-L (998-0139-00) ships without ERO glass, making it the standard configuration for controlled-light environments. The LX55U-L-ERO (998-0230-00) adds Planar's optically-bonded Extended Ruggedness and Optics glass, improving ambient light rejection and enabling touch overlays for public-facing or interactive deployments.

Does the LX55X-L support 4K sources?

Yes. The built-in Planar Big Picture Plus Video Controller supports 4K at up to 60Hz via HDMI 2.0 and DisplayPort 1.2 inputs. Multiple 4K sources can be scaled and routed across the video wall or windowed into defined zones without an external processor.

What does the G3 designation mean?

G3 refers to the third generation of Clarity Matrix architecture. Key G3 improvements over G2 include enhanced off-board electronics, the updated Remote Power Supply with n+1 redundancy, improved Big Picture Plus processing throughput, and native HDMI 2.0/DisplayPort 1.2 connectivity.

Can this display operate in portrait orientation?

The LX55X-L is configured specifically for landscape orientation with the EasyAxis Mounting System optimized for that installation. Planar offers separate VESA-based variants for installations requiring portrait or custom-angle mounting.

How is serviceability handled in a large video wall array?

The off-board electronics design means the RPS and VC chassis are separately mounted and field-replaceable without disturbing the display panels. The EasyAxis Mounting System also enables front-service access, allowing panel swaps from the face of the wall.

Is Leyard WallDirector software included?

Yes. Leyard WallDirector is bundled with Clarity Matrix G3 systems and provides browser-based management, layout presets, source routing, and centralized health status monitoring across all components in the video wall installation.
