Samsung 55" QD-OLED TV with Neural Quantum Processor 4K and 144Hz Gaming

QD-OLED Picture Quality:

The QE55S90HATXXU combines OLED contrast with Quantum Dot colour accuracy, delivering true blacks and naturally bright, saturated colour across the full screen. The Ultra Viewing Angle with Anti-Reflection Screen means picture quality holds up from every seat in the room, not just directly in front.

Neural Quantum Processor 4K:

The Neural Quantum Processor 4K uses AI and 20 neural networks to analyse and optimise each scene as it plays. It adjusts brightness, amplifies contrast, clarifies dialogue over background noise, and upscales lower-resolution content towards 4K quality automatically.

Gaming at 4K and 144Hz:

Four HDMI ports include HDMI 2.1 support for next-generation consoles, delivering ultra-low input lag and 4K gameplay at up to 144Hz. Auto Low Latency Mode (ALLM) detects your source and adjusts settings automatically, so you do not need to manually switch picture modes when moving between gaming and viewing.

Gaming Hub and Smart Features:

The built-in Gaming Hub brings cloud gaming platforms including Xbox, Nvidia GeForce Now, and Blacknut together on the TV without requiring a console. The Tizen operating system gives access to Netflix, Amazon Prime Video, Disney+, Apple TV, BBC iPlayer, and dozens of other streaming services, alongside Samsung SmartThings for home integration and Bixby voice control.

Setup and Care

Getting Started:

The Tizen smart platform guides you through initial setup on first power-on, including Wi-Fi connection, app sign-in, and picture calibration. HDMI 2.1 ports are clearly labelled on the rear panel for straightforward console and soundbar connection.

Wall Mounting:

The TV is VESA mount compatible; check the specifications sheet or Samsung's support site for the correct VESA pattern before purchasing a bracket. Wall mounting should be carried out by a qualified installer.

Screen Care:

Clean the QD-OLED panel with a soft, dry microfibre cloth. Avoid liquid cleaners directly on the screen surface. The anti-reflection coating is effective in well-lit rooms and does not require any additional treatment.

Long-Term Use:

OLED panels benefit from varied content to support even panel wear over time. Samsung's built-in pixel management features handle this automatically in the background during normal use.
