LG QNED LG QNED84B QNED evo AI 100" 4K HDR Smart Mini-LED Review

This is a 100-inch giant with top-tier gaming features (92nd percentile) and elite HDR support (96th percentile). But its core picture quality sits in a mediocre 43rd percentile. Buy it for the immersive size and specs, not for reference-grade image fidelity.

Let's start with the number that matters: 100 inches. The LG QNED84B is a massive Mini-LED TV that puts you in the 93rd percentile for display size in our database. That's a statement piece. For features, it's packing a 120Hz native refresh rate, Dolby Vision, and a full suite of gaming tech like FreeSync and ALLM, which lands it in the 92nd percentile for gaming. This is a TV built for a big room and a big experience.

Our scoring puts it as a strong all-rounder, with its best scores in gaming (83.8/100) and movies (76.4/100). It's weakest for outdoor use, but let's be real, you're not moving this 150-pound behemoth onto the patio. The core pitch is simple: huge screen, modern gaming features, and LG's solid smart TV platform.

This TV's performance profile is a tale of two halves. On the high end, it absolutely shines. Its HDR support is in the 96th percentile, meaning it's ready for the best Dolby Vision and HDR10 content you can throw at it. For gamers, that 92nd percentile ranking is backed by the 120Hz panel, VRR, and Auto Low Latency Mode, making it a genuinely smooth experience. Connectivity is also top-tier at the 90th percentile, with four HDMI ports and eARC for your soundbar.

Where it stumbles a bit is in the core picture quality department, landing in the 43rd percentile. That means while the HDR format support is excellent, the actual panel's contrast and black level performance likely can't match a high-end OLED or a more premium Mini-LED. The audio score is decent at the 71st percentile, but for a screen this size, you'll definitely want a separate sound system.

The price range is tight, between $4497 and $5000. That's a lot of money, but you're paying for the 100-inch canvas first and foremost. At the low end of that spread, you're getting a better deal, but it's still a premium for size over absolute peak picture quality. When you compare it to, say, a 77-inch OLED that might cost the same, you're trading perfect blacks for a much larger screen. It's a value proposition centered entirely on immersion.

Stacked against the competition, the LG's size is its main weapon. The Sony BRAVIA 5 85" is a more refined Mini-LED but is smaller and likely more expensive. The Hisense U6 series is far cheaper but can't match the gaming specs or size. The most interesting fight is with LG's own 77" OLED G5. The OLED will destroy it in contrast and picture quality (especially in dark rooms), but you lose 23 inches of screen real estate. The Samsung QN800D offers 8K, but that's overkill at this size and price. For a dedicated home theater/game room where size rules, the QNED84B makes a case. For critical movie watching in a dark room, the OLED is the smarter tech pick.

Skip this TV if you're a videophile on a budget. That 43rd percentile picture quality score is a red flag if your main goal is the best possible image. You'd be better served by a smaller, higher-ranked OLED or a more advanced Mini-LED TV. Also, if your room isn't massive, a 100-inch screen will be overwhelming. And if you like to move your TV around, the 150-pound weight is a hard pass.

We recommend the LG QNED84B if your top priority is a gigantic, feature-complete screen for a mixed-use media room. The 120Hz gaming support and excellent HDR compatibility are real strengths. But we can't ignore the middling picture quality score. You're buying the scale and the feature set, not the absolute best image. If you want the best picture for your money, a smaller high-end OLED or a more premium Mini-LED might serve you better. This is for the person who walks in and says 'I want the biggest TV that still has all the modern bells and whistles.'
