The only 8K with real sound — an 8.2-ch panel-actuator system and Dolby Vision, at the one size where 8K is visible, for less than a 75-inch QN990F.

BUILT-IN SOUND
8.2-channel, 85 W Acoustic Multi-Audio+ — actuators turn the panel itself into a speaker; it beats any current Samsung 8K on built-in audio.
DOLBY VISION
It carries Dolby Vision — Samsung's 8K sets refuse to license it, so Disney+ and Apple TV+ originals keep their grade.
VISIBLE 8K
85 inches — the only size where 8K measurably beats 4K at a normal 8 ft seating distance.
PEAK BRIGHTNESS
~3,500 nits from the XR Backlight Master Drive full-array — roughly double the QN990F's HDR peak.
MOTION AND UPSCALING
Cognitive Processor XR — Sony's reference-grade upscaling and motion handling for film and sport.
PRICE
~$4,077, down ~49% from ~$8,000 — cheaper than a 75-inch QN990F.

  The catch — co-equal billing, always

It's a dead-end TV. Sony exited 8K in 2025 and the Z9K is 2022 hardware in liquidation — Amazon shows one unit left, no new firmware features will ever ship, and only 2 of its 4 HDMI ports are HDMI 2.1, so more than two next-gen sources need an AVR.

Dealbreaker? Runner-up №1 (QN900D 85") trades the sound for stock and a platform Samsung still updates ↓

Adjacent verdicts — same method

Traps — this verdict avoids

Trap 01

The content that doesn't exist

No major streamer offers 8K in 2026 — not Netflix, Disney+, Prime Video, Apple TV+ or Max — and Blu-ray tops out at 4K. Every benefit on these TVs comes from AI upscaling, not source resolution.

Trap 02

Pixels you can't resolve

At a typical 8 ft seating distance, THX/SMPTE pixel-pitch math puts 8K indistinguishable from 4K below ~85 inches, even with 20/20 vision. Below that size you are buying an upscaler and a badge.

Trap 03

The 65-inch inversion

Samsung's 65-inch QN900D is stranded near ~$4,998 with one unit left — $2,700 more than the same TV at 75 inches (~$2,298). Clearance has scrambled the 8K ladder: price every size before you buy.
