Planar Simplicity P Series SLP55 4K LCD Display, 55in diagonal

Product Overview

The Planar Simplicity P Series SLP55 is a 55" 4K UHD commercial LCD display (SKU: 998-3927-00) built for continuous 24x7 digital signage operation. It combines cybersecurity mitigation (EN 303 645 certified), ENERGY STAR efficiency, 500 nit brightness, a narrow logo-free bezel, and a proprietary Android 10.0 OS — all in a slim profile supporting landscape or portrait installation for wayfinding, menu boards, advertising, and emergency messaging applications.

Product Description

The SLP55 is Planar's 55" flagship in the Simplicity P Series — the latest-generation commercial signage platform featuring enhanced cybersecurity over prior Simplicity generations. The display intentionally omits onboard Wi-Fi to reduce the network attack surface and is certified to the European EN 303 645 IoT cybersecurity standard. A 500 nit direct-lit LED panel with 25% haze anti-glare surface treatment provides clear visibility in mixed-lighting environments. Connectivity includes dual HDMI 2.0 (HDCP 2.2), USB-C, VGA, USB 3.0, USB 2.0, and MicroSD. Content management is handled via the proprietary Android 10.0 OS, supporting USB, MicroSD, internal storage, web page, and cloud-based content apps. A 30,000-hour LED backlight life and 3-year Advance Exchange warranty ensure low total cost of ownership.

Frequently Asked Questions

Why does the SLP55 not have built-in Wi-Fi?

Content can be delivered via USB drive, MicroSD card, internal storage (32 GB), web page rendering, or a cloud-based content app (requires subscription) through the proprietary Android 10.0 OS.

Yes. The display supports landscape and portrait mounting, providing flexibility for tall-format digital signage such as totems and wayfinding panels.
