The iiyama ProLite LH5565UHSB-B1 is a 55-inch vivid-bright 4K professional display designed for retail digital signage, corporate communications, hospitality, information displays and commercial AV installations. It combines an IPS panel, 800 cd/m² brightness, 4K UHD resolution and continuous 24/7 operation.
Built-in Android 11, iiSignage², iiControl, iiShare, Signal FailOver and EShare provide a flexible integrated signage platform for remote content management, device control and wireless screen sharing.
The iiyama LH5565UHSB-B1 uses a 54.6-inch IPS panel with 800 cd/m² brightness, helping advertising, product imagery, menus and business content remain clear in bright indoor environments.
Its larger 55-inch screen provides more visual impact than the 43-inch model, making it particularly suitable for retail spaces, receptions, hospitality, corporate environments and customer-facing digital signage.
Vivid-bright output helps digital signage remain clear in brighter indoor environments.
Designed for round-the-clock professional digital signage use.
3840 × 2160 resolution provides detailed images, graphics and text.
Install compatible signage and business applications directly on the display.
Integrated content management supports remote signage updates and control.
Automatically moves to an available source if the primary input fails.
iiSignage² is iiyama's integrated content management system for compatible digital signage displays.
It allows messaging, advertising and other screen content to be managed remotely, helping businesses update customer-facing displays without visiting each screen individually.
FailOver automatically detects whether the selected input still has an active signal.
If the main source becomes unavailable, the display can switch to another prioritised input, helping maintain visible content in business-critical installations.
Built-in Android 11 allows compatible third-party signage applications and CMS platforms to run directly on the screen.
The integrated hardware combines an octa-core processor, 4GB RAM and 32GB internal storage.
The iiyama ProLite LH5565UHSB-B1 is rated for 24 hours per day, seven days per week operation.
That makes it suitable for always-on signage, information displays, retail environments and business-critical content.
The native 3840 × 2160 resolution at 60Hz provides four times the pixel count of Full HD.
This extra resolution helps detailed product imagery, menus, pricing, wayfinding and promotional graphics remain crisp across the larger 55-inch screen.
The LH5565UHSB-B1 includes 2 × HDMI 2.0, DisplayPort 1.2, 2 × USB, Gigabit-style network connectivity and RS-232C control.
Built-in Wi-Fi supports networked signage, while integrated 2 × 10W speakers provide audio for compatible content.
