This 55” 4K UHD screen combines cutting-edge performance with outstanding flexibility, making it the perfect fit for fashionable, artistic, and premium commercial spaces.

What sets the LH5581UHSG-1AG apart is its innovative removable frame: magnetically attached and easy to customize with wraps or designs of your choice. Whether you want it to blend seamlessly into a stylish boutique, complement an art gallery, or add flair to a high-end lobby, this display adapts to your vision.

Powered by Android 14 OS and equipped with iiSignage² (CMS), iiControl (DMS), and iiShare (Wireless Presentation), managing content is as smooth as its minimalist design suggests. With built-in WiFi, robust 24/7 operation, and exceptional connectivity options, the LH5581UHSG-1AG offers both form and function.

Its anti-glare coating, slim profile, and versatile installation options with included wall mounting bracket, ensure that your message stands out — and your space stays elegant.

Frame it Your Way

The magnetic removable frame is super easy to wrap in any design you like - match your mood, your room, or your brand. No tools, no hassle. Just pop it off, wrap it up, and you’re good to go. Custom style made simple. For a clean, frameless look, you simply leave the frame off - perfect for seamless integration in any environment.

Android OS
Thanks to Android OS, you can easily customize the display to your needs by installing applications directly to it.
