Sharp MA551-PT – 55" 4K UHD Professional Display with PCAP Touch

Product Overview

The Sharp NEC MA551-PT is a 55-inch 4K UHD commercial touch display that pairs the MA Series wide color gamut U-IPS panel with pre-installed PCAP (projected capacitive) touch for interactive digital signage and collaborative meeting spaces. Rated for commercial duty with 500 cd/m2 brightness and the SpectraView Engine for precise color control, this professional touch screen display suits wayfinding kiosks, interactive retail signage, corporate lobbies, and command-and-control environments. Its modular slot design accepts Intel Smart Display Module and Raspberry Pi Compute Module 4 compute options for all-in-one interactive deployments.

Product Description

The MA551-PT builds on the fully commercial NEC MA Series large format display platform, adding responsive PCAP touch to a wide color gamut 4K panel driven by the proprietary SpectraView Engine. The 10-bit U-IPS panel reproduces more than 1.08 billion colors with custom gamma options including sRGB, Rec. 1886, DICOM, and HDR (Hybrid Log Gamma and ST2084 PQ), giving integrators calibrated accuracy for color-critical signage and visualization work. A full metal chassis provides the structural rigidity required for public-space installation in landscape or portrait orientation. Connectivity supports DisplayPort 1.4 and HDMI 2.0 inputs with enhanced daisy chain output over both HDMI and DisplayPort for video wall and multi-display signage distribution. Bidirectional external control over LAN or RS-232C allows straightforward integration into Crestron, Extron, and other commercial AV control systems, while free NaViSet Administrator 2 software centralizes fleet management across large display deployments. Failover input detection automatically switches to a secondary or tertiary source if the primary signal drops, protecting always-on digital signage uptime. Multi Picture Mode shows multiple sources simultaneously without external processing hardware. The display accepts Intel SDM Small or Large modules and the Raspberry Pi Compute Module 4, enabling embedded media players and interactive applications without an external PC.

Technical Specifications

Frequently Asked Questions

What is the difference between the MA551-PT and the standard MA551?

The MA551-PT is the same MA Series 55-inch 4K wide color gamut display with a factory pre-installed PCAP touch overlay, eliminating the need for a field-installed touch kit and preserving the commercial warranty.

Does PCAP touch work with gloves or styluses?

Projected capacitive touch responds to bare fingers and capacitive-compatible styluses. It provides the fast, smooth response expected for interactive wayfinding, kiosks, and annotation in meeting spaces.

Can the MA551-PT run signage content without an external player?

Yes. The display accepts Intel Smart Display Module (Small or Large) compute modules and the Raspberry Pi Compute Module 4, allowing media playback and interactive applications to run inside the display chassis.

How does it integrate with AV control systems?

The display supports bidirectional external control over LAN and RS-232C, so it can be monitored and controlled from common commercial control processors. NaViSet Administrator 2 is available free for centralized multi-display management over the network.

Can it be installed in portrait orientation?

Yes. The MA551-PT supports both landscape and portrait installation, making it suitable for menu boards, directories, and vertical kiosk enclosures.

What warranty is included?

Sharp/NEC includes a full 3-year commercial warranty covering parts and labor. Creation Networks can assist with warranty service coordination and extended coverage options.

Is the display rated for 24/7 operation?

The MA Series is a fully commercial display platform with a metal chassis built for extended-duty digital signage. Confirm your duty-cycle requirements with our team when planning always-on deployments.
