Product Overview
The Planar MX55HDU-P is a 55-inch Clarity Matrix G2 LCD video wall panel configured for portrait-only orientation, delivering 800-nit high brightness for demanding ambient light environments. With Full HD 1920x1080 resolution, a 1.7mm tiled bezel width, LED backlighting, and 24/7 mission-critical design, this panel is engineered for installations where panels must be mounted vertically to maximize vertical display height. The G2 platform includes 4K input capability, 10-bit color processing, and Planar Big Picture Plus Video Wall Processing for multi-source management across large arrays. Optional ERO protective glass and Fiber Video Extension make the MX55HDU-P adaptable to both public-space and secure government deployments.
Product Description
The Planar MX55HDU-P 55-inch Clarity Matrix G2 portrait video wall panel delivers 800 nits of brightness specifically for environments where high ambient light and portrait panel orientation are required simultaneously. Portrait-oriented video walls are commonly specified for narrow digital signage applications, retail window displays, wayfinding columns, and certain control room configurations where tall, narrow display columns maximize the information density of the installation. The 1.7mm tiled bezel width creates a nearly seamless surface when panels are arranged in portrait arrays, and the EasyAxis Mounting System enables precise vertical alignment with an installed depth of just 3.6 inches. Planar Big Picture Plus Video Wall Processing allows 4K inputs at 60Hz to be scaled across the video wall or any section, with Picture-in-Picture and multi-window support. The 10-bit color processing improves color depth and uniformity across panel arrays, reducing visible color variation between individual panels. Redundant power supply modules with hot-swap capability ensure continuous operation during power supply servicing. WallNet health monitoring with SNMP provides centralized status visibility for the entire video wall installation. Optional ERO optically-bonded glass enhances contrast and provides a durable protective surface for public-facing deployments. SKU 997-9186-00 ships with a 3-year limited warranty.

Frequently Asked Questions
- Is the MX55HDU-P restricted to portrait orientation only?
- Yes. The MX55HDU-P is a portrait-only configuration. For landscape-oriented video walls requiring 800-nit brightness, the MX55HDU-v (VESA) or MX55X-L models should be specified instead.
- What is the advantage of 800-nit brightness in portrait signage?
- 800-nit panels remain highly readable under direct artificial lighting, near windows, or in brightly lit retail and transportation environments where 500-nit panels can appear dim or washed out.
- Does the MX55HDU-P support 4K inputs?
- Yes. The Clarity Matrix G2 platform supports 4K input capability processed through Planar Big Picture Plus Video Wall Processing at up to 60Hz.
- What is the bezel width between portrait panels?
- The MX55HDU-P achieves a 1.7mm tiled bezel width between adjacent panels, creating a near-seamless vertical display surface in portrait array configurations.
- How does the redundant power supply work?
- A single power supply module can drive up to eight displays, and redundant modules provide continuous operation if one supply fails. Failed modules can be replaced without shutting down the video wall.
- What warranty is included?
- The MX55HDU-P includes a 3-year limited warranty from Planar.
