LG QNED84B 55"
The Mini-LED backlight with Dynamic QNED Color Pro and the α8 AI Processor 4K Gen3 delivers 100% color volume for accurate images. A native 120Hz panel with FreeSync and HDMI 2.1 makes this a strong value for smooth gaming, while the webOS 26 platform integrates Google Gemini and Microsoft Copilot for voice-driven content discovery. This TV is best for smart home enthusiasts and console gamers who want high-refresh performance and AI-assisted navigation without a premium price tag.
Snapshot
The 30-Second Version
The LG QNED84B is a 120Hz Mini-LED TV with a killer smart platform that ranks in the 91st percentile. Picture quality is vibrant and gaming is smooth, but the lack of Dolby Vision and just-okay audio hold it back. It's a fantastic buy if you can find it at the lower end of its wide $421 to $1006 price range.

The proof
Performance
This set is a solid performer where it counts for most people. The 120Hz native refresh rate paired with FreeSync and ALLM pushes its gaming score into the 86th percentile, which means motion is buttery smooth whether you're on a console or PC. Picture quality is strong, sitting in the 80th percentile, with the Mini-LED backlight and Dynamic QNED Color Pro delivering punchy, accurate colors. The weak spot is audio. The 2.0 channel setup with virtual surround is middle-of-the-pack at the 60th percentile, so you'll definitely want a soundbar to match the picture quality. HDR brightness is also just average, which holds it back from being a true home theater powerhouse.

vs Competition
Stacked against the heavy hitters, the LG carves out a nice niche as the smart-home champ. The Sony BRAVIA 9 and Samsung Neo QLED QN70F will beat it on pure HDR impact and picture processing, but you'll pay a premium for that. The TCL QM8K and Hisense U8 Series are its most direct rivals, often offering better brightness and Dolby Vision for a similar price, but they can't quite match LG's polished webOS experience and AI integration. If your priority is a seamless smart TV experience over absolute peak brightness, the LG is the more pleasant daily driver.

Value & Pricing
Pricing on this thing is all over the map, with a spread from $421 to $1006 depending on where you look. At the low end, it's a steal for a 55-inch Mini-LED with a 120Hz panel and top-tier smart features. At the high end, you're creeping into territory where a better-specced Sony or Samsung starts to make more sense. If you can snag it closer to that $421 mark, the value proposition is hard to beat. Just shop around before you click buy.

Overview
LG's QNED84B is their 2026 entry into the increasingly crowded Mini-LED space, and it brings a lot of the right specs for a mixed-use living room TV. You get a native 120Hz panel, the latest webOS 26, and some genuinely useful AI tricks baked in with Google Gemini and Microsoft Copilot access right from the remote. It's clearly aimed at someone who wants a smart, vibrant picture for movies and sports but doesn't want to completely break the bank on an OLED.
But here's the thing: the Mini-LED backlight here is doing a lot of heavy lifting for the marketing, and the HDR performance is just okay. It supports HDR10 and HLG, but there's no Dolby Vision, which feels like a miss at this level. The smart features score through the roof in our database, landing in the 91st percentile, so if you live in a smart home and want a TV that plays nice with everything, this one's got your back.
Common Questions
Q: Does this TV support Dolby Vision for movies?
No, it's limited to HDR10 and HLG. If Dolby Vision is a must-have for your streaming and 4K Blu-rays, you'll need to look at competitors like the TCL QM8K or Hisense U8 Series.
Q: Is the 120Hz panel good for PS5 and Xbox Series X gaming?
Absolutely. With FreeSync, ALLM, and HDMI 2.1 support, it can handle 4K at 120Hz from current-gen consoles, making gameplay feel incredibly responsive and fluid.
Q: How good are the built-in speakers?
They're serviceable for casual TV watching but pretty thin. The 2.0 channel setup lacks bass, so we strongly recommend pairing it with even a budget soundbar for a much better experience.
Who Should Skip This
Home theater purists should skip this one. If you're building a dedicated dark room setup and care deeply about specular highlight detail and deep black levels, the lack of Dolby Vision and average HDR brightness will leave you wanting more. Look at an OLED or a higher-end Mini-LED from Sony or Samsung instead.
Verdict
The LG QNED84B is a fantastic choice if you want a TV that's a joy to use every day. It's fast, the smart platform is best-in-class, and the picture is vibrant and smooth for gaming and sports. You should buy this if you value a frustration-free smart experience and great motion handling above all else. If you're a cinephile who demands the best HDR and deep, inky blacks for a dedicated dark room, you'll want to look at an OLED or a higher-end Mini-LED with Dolby Vision.
