SAMSUNG QN65LS03HWFXZA 65" Neo QLED TV with HW-S800D Soundbar (2026)

Neo QLED TV with integrated soundbar

The Samsung QN65LS03HWFXZA is a 65 inch Neo QLED television that ships with the HW-S800D soundbar. It targets viewers who want a single-box solution for 4K picture and Dolby Atmos audio without separate components. The set runs Samsung's Tizen smart platform and includes a Wireless One Connect box to keep cables out of sight. Buyers who need more than five HDMI inputs or a dedicated centre channel should look elsewhere.

Sustained brightness and motion handling

Mini LED backlighting with Supreme Mini LED Dimming maintains contrast during long HDR sessions rather than peaking only in short bursts. The NQ4 AI Gen3 processor drives 4K AI Upscaling Pro and Real Depth Enhancer continuously, while Motion Xcelerator 144Hz and DLG 240Hz keep motion clear across extended gaming or sport marathons. VRR and ALLM stay active without throttling, so variable refresh rates remain stable for the full duration of a match or campaign.

Thermal design and acoustic profile

The slim Frame Pro chassis dissipates heat across a large rear surface, allowing the mini LED array to run at consistent output without audible fan noise. Q-Symphony Pro blends the TV's 2.0.2 channel speakers with the soundbar for a wider front stage at typical living-room volumes. Adaptive Sound Pro and Adaptive Picture adjust output in real time, keeping power draw steady whether the screen shows bright landscapes or dark interiors.
