Buy on Amazon

Pros

+ Same Alpha 8 AI Processor Gen 3 as the flagship QNED90, at a fraction of the price
+ AI Super Upscaling shared only with the QNED90
+ Massive 100" size for genuine home-theater scale
+ webOS 26 with the same Sports Portal and AI features as the flagship

Cons

− Lacks the QNED90's 165Hz VRR and 330Hz Motion Booster
− Peak brightness, refresh rate, and HDMI 2.1 port count not independently confirmed
− US retail SKU naming may appear slightly differently by retailer (e.g. QNED84-series badging)
− LG's 2026 US QNED range is QNED92B and QNED84B only; this model was published under a 2025-era name that does not exist in the current US lineup and has been corrected

LG QNED84B (100-inch) review: what the specs say

LG's 100" mid-flagship QNED — the QNED90's processor at cinematic scale. At $3,999.99, LG's 2026 model sits at the premium end of the category — the TVs we compare run from $279.99 to $12,999.99. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.

Its strongest showing is Smart Platform at 8.8/10 — OS responsiveness, app ecosystem, and voice assistant support. The weakest is Value at 6.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.

Worth knowing before you buy: lacks the QNED90's 165Hz VRR and 330Hz Motion Booster; and peak brightness, refresh rate, and HDMI 2.1 port count not independently confirmed. Every specification on this page comes from LG's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
