Product information

Description

The BenQ ST5504 is a 55" (139.7 cm) digital signage flat panel offering 4K Ultra HD (3840×2160) resolution on an ADS LCD panel with 350 cd/m² brightness and a typical contrast ratio of 1200:1. Designed for 18/7 operation, the display runs Android and integrates a built‑in processor, dual speakers, VESA mounting and connectivity options suitable for retail, corporate and public information environments. The panel supports both portrait and landscape orientations, features an anti‑glare screen with a 25% haze value to reduce reflections, and includes management and security tools for centralized content delivery and device control.

Advantages

The ST5504 delivers crisp 4K visuals and reliable 18/7 performance while providing easy content creation and distribution through BenQ’s X-Sign platform and Device Management Solution (DMS). Its anti‑glare surface and 10‑bit color support improve viewing comfort and image clarity in well‑lit spaces. Built‑in audio and slim bezels enable clean, integrated installations, and hardware plus software security features protect against unauthorized access. Remote provisioning, firmware scheduling and Wake on HDMI/Wake on LAN simplify deployment and ongoing maintenance.

  • Retail storefronts and promotional displays

  • Educational facilities — cafeterias, corridors and libraries
  • Transportation hubs and public information screens

How to use

Mount the ST5504 using VESA-compatible brackets in the chosen orientation, connect power and network (Ethernet or configured Wi‑Fi), and power on the display. Use the built‑in Android environment or connect to BenQ X-Sign for content creation and scheduling. Configure device settings and security policies via BenQ DMS for remote management, firmware updates and power scheduling. For local playback, load compatible media or apps on the device; for wireless sharing, use InstaShare 2 to cast from supported laptops, tablets or smartphones.

Usage recommendations

Place the display where ambient reflections are minimal to take advantage of the anti‑glare coating; use portrait orientation for vertical content such as menus or wayfinding and landscape for video and mixed media. Enable Wake on HDMI or Wake on LAN to reduce power consumption when idle and schedule firmware updates during off‑hours via DMS to keep the display secure and up to date.
