Pros & Cons
👍 Pros
- 85 inches of 4K screen at typical living room distances delivers a genuinely cinematic field of view — the size upgrade from 65 or 75 inches is immediately noticeable and immersive.
- Google TV aggregates recommendations across all streaming services into a unified home screen, so finding something to watch is faster than managing separate apps manually.
- Full HDR format support — Dolby Vision, HDR10+, HDR10, and HLG — means this TV renders HDR content optimally from Netflix, Prime Video, and broadcast sources without format gaps.
- Game Accelerator 120 with VRR and Auto Game Mode (ALLM) keeps gaming input lag low and eliminates screen tearing for smoother gameplay on compatible consoles and PCs.
- The built-in subwoofer adds bass presence that standard flat-panel TV speakers can't produce — Dolby Atmos content sounds meaningfully fuller than on a comparable set without one.
👎 Cons
- The native panel refresh rate is 60Hz — the 120Hz Game Accelerator mode operates via VRR, not a true high-refresh panel, which is a real distinction for competitive gaming purists.
- LED backlighting cannot match OLED for black levels or per-pixel contrast — dark scenes will show some backlight bleed or glow in the blacks that OLED eliminates entirely.
- An 85-inch television requires real estate: a TV stand or mount rated for its size and weight, and enough viewing distance (ideally 9–12 feet) to avoid an overwhelming picture.
- Bluetooth audio pairing can introduce sync latency with some wireless headphones and soundbars — wired or HDMI ARC/eARC connections remain more reliable for lip-sync accuracy.
- The AIPQ processor's AI upscaling is competent but trails the processing sophistication of Sony's X-Reality Pro or Samsung's Neo Quantum engine on difficult source material.
