Samsung QN55QN90D – 55" Neo QLED 4K TV with Anti-Reflective Screen

Product Overview

The Samsung QN55QN90D is a 55-inch Neo QLED 4K smart TV featuring an anti-reflective screen coating, Mini-LED backlighting, and RS-232c serial control for commercial AV integration. It is engineered for deployment in ambient-light-heavy environments such as conference rooms with large windows, training rooms, and open collaboration spaces where screen glare reduces presentation visibility. With four HDMI 2.1 inputs and Tizen OS, it supports standard AV system integration workflows and digital signage applications.

Product Description

The QN55QN90D builds on the QN85D platform with the addition of an anti-reflective panel coating, a key differentiator for commercial spaces with mixed or high ambient lighting conditions. Samsung's Quantum Matrix Technology drives the Mini-LED backlight array, enabling precise local dimming across a large number of zones for accurate contrast control. The Neural Quantum Processor 4K performs real-time upscaling and AI scene detection to maintain consistent image quality across different source types, including USB media, streaming content, and HDMI video feeds. RS-232c control integration makes the display compatible with Crestron, AMX, and Extron-based room control systems. The four HDMI 2.1 ports handle simultaneous multi-source connectivity for conferencing systems, PCs, and media players. Tizen OS supports Samsung's MagicINFO content management system and URL Launcher for scheduled digital signage playback. Wi-Fi 5 and Bluetooth 5.2 provide wireless connectivity for screen mirroring and peripheral pairing.
