Samsung QE43QN73H — 43" Neo QLED 4K Smart TV (2026)

The Samsung QE43QN73H brings Samsung's 2026 Neo QLED technology to a compact 43-inch screen — combining Quantum Mini LED backlighting, the NQ4 AI Processor, and Samsung's latest Vision AI Companion features. A brilliant all-rounder for everyday viewing, sport and streaming, the QN73H delivers vivid, detailed 4K picture quality with the smart features Samsung's Neo QLED range is known for.

Neo QLED with Quantum Mini LED

Quantum Mini LED backlighting with Ultimate Mini LED Dimming delivers precise, concentrated control over lighting zones, revealing more detail in shadows and highlights alike. Samsung's Real QLED technology delivers 100% Colour Volume*, backed by PANTONE Validated colour accuracy, with Contrast Enhancer and Color Booster Pro keeping colour vivid and contrast sharp across a Wide Viewing Angle, so picture quality holds up well even off-centre.

*Measured to DCI-P3 standard, certified by VDE.

NQ4 AI Processor

Samsung's NQ4 AI Processor handles 4K upscaling and AI Customization, continuously adapting the picture to suit your content. Filmmaker Mode preserves content exactly as directors intended, while the HDR Brightness Optimizer and EyeComfort Mode automatically adjust the picture to suit your room and reduce eye strain during longer viewing sessions.

20W Sound with Object Tracking Sound Lite

A 20W, 2-channel built-in speaker system is paired with Object Tracking Sound Lite for directional audio that follows the action on screen, while Active Voice Amplifier and Adaptive Sound+ keep dialogue clear no matter what you're watching. Connect a compatible Samsung soundbar to unlock Q-Symphony, combining the TV's speakers with your soundbar for a fuller soundstage.

Console-Ready Gaming Features

The QN73H is built with console gaming in mind. Auto Low Latency Mode (ALLM) automatically switches to the TV's lowest-latency Game Mode the moment a console is detected, while HGiG support ensures accurate HDR gaming tone-mapping. The on-screen Game Bar, Mini Map Zoom, Dynamic Black EQ and Super Ultra Wide Game View give you more control and visibility during gameplay, and the Samsung Gaming Hub brings cloud gaming platforms together in one place — no console, downloads or storage required.

Vision AI Companion

Samsung's 2026 Vision AI Companion brings a more intelligent, personalised viewing experience to the QN73H, including AI Soccer/Football Mode which automatically optimises picture and sound for the match.

Tizen Smart TV & Entertainment

Running Samsung's Tizen operating system, the QN73H gives you instant access to Netflix, Disney+, YouTube and more, with thousands of free shows and channels on Samsung TV Plus — no subscription required. Built-in Bixby and compatibility with Alexa and Google Assistant provide hands-free control, while SmartThings Hub and Matter support turn the QN73H into a hub for your connected home. Apple AirPlay makes it simple to stream from compatible Apple devices, and Samsung Knox multi-layer security runs continuously in the background to keep your data protected, and a 7-Year OS Upgrade Guarantee ensures the TV stays up to date with the latest features for years to come.
