The 30-Second Version
The LG QNED84B is a 100-inch 4K MiniLED TV with strong gaming performance, Dolby Vision support, and a useful smart platform. It's an excellent giant-screen value, especially when you can find it for around $4000. Just be ready to add a soundbar and don't expect perfect black levels in the dark.
Overview
So you want a TV that fills an entire wall, but you don't want to sell a kidney for a projector setup. The LG QNED84B is a 100-inch 4K MiniLED behemoth that currently sits between $4000 and $6180 across different vendors. That's a serious chunk of change, but when you factor in the sheer screen real estate and the fact that it doesn't require a pitch-black room, this TV makes a compelling argument for being the centerpiece of a home theater. It runs LG's webOS 26, which now has Google Gemini and Microsoft Copilot baked in, so you can bark commands at the Magic Remote and actually get useful answers most of the time. The α8 AI Processor 4K Gen3 handles upscaling and motion, and you get full HDR support with Dolby Vision, HDR10, and HLG.
If you've been searching for a 100-inch TV under $6000, this one is probably already on your radar. It's got a 120Hz native panel with all the gaming goodies: FreeSync Premium, VRR, ALLM, and HDMI 2.1 on all four inputs. Streaming fans will love the built-in Apple AirPlay and Google Cast, and the thing actually hits 100% color volume for vivid, accurate colors. It's not just a big screen; it's a big screen that tries to be smart in all the right ways.
Performance
Numbers-wise, the QNED84B sits in the 79th percentile for picture quality and gaming, and 88th for HDR. That means it's one of the better performers in its class, especially when you turn on a Dolby Vision flick. Bright highlights pop nicely, colors look accurate thanks to the Dynamic QNED Color Pro upscaling, and the MiniLED backlight with Precision Dimming Pro does a decent job at keeping black areas dark, though you'll still catch some blooming around bright objects against dark backgrounds. The 120Hz refresh rate and Motion Pro handling make sports and movies look fluid, and if you drag a high-end PC or a PS5 into the mix, VRR and ALLM kick in automatically to keep tearing and lag at bay.
For gaming, you're looking at input lag in the ballpark of 10ms in game mode, which is more than fast enough for all but the most twitchy esports players. The 4-channel speaker setup puts out clear dialogue and a bit of width, but there's almost no bass, so you'll absolutely want a soundbar. Audio lands in the 67th percentile, which is middle of the pack. It gets loud enough for a large living room, but don't expect Dolby Atmos to rumble your couch without external help.
Pros & Cons
Pros
- Massive 100" screen gives you an actual cinema feel at home 90th
- MiniLED backlight with 100% color volume produces vibrant, accurate hues 88th
- Four HDMI 2.1 ports with VRR, ALLM, and FreeSync Premium for gamers 82th
- webOS 26 is snappy and the inclusion of Google Gemini is genuinely useful 80th
- 120Hz native refresh rate makes motion ultra-smooth across movies and games
Cons
- Built-in audio is underwhelming; you'll need a soundbar for any kind of punch 30th
- Blooming around bright objects is visible when the lights are low, typical of MiniLED
- Extremely heavy at 65.9 kg, so wall mounting requires serious hardware
- Only 16 user reviews means long-term reliability is still an open question
- No ATSC 3.0 tuner, so over-the-air 4K broadcasts are off the table

Value & Pricing
With a price gap of over $2180 across different sellers, it pays to shop around. Some retailers have this 100-inch monster listed at $4000, which is aggressively competitive against other jumbo TVs. The Samsung Neo QLED QN900F, for instance, often commands a significant premium for 8K resolution. At four grand, the LG undercuts a lot of big-screen competition while still offering MiniLED contrast and a full suite of gaming features. If you can snag it on sale, it's a lot of TV for the money. Just don't pay full sticker price if you can help it.
Price History
vs Competition
Stacked against the Samsung Neo QLED QN900F, the LG QNED84B trades blows in a battle of size versus resolution. The Samsung is an 8K set with even better brightness and a more refined local dimming algorithm, but it's usually much more expensive and not available in a 100-inch flavor that won't bankrupt you. The TCL QM8K Series is a fantastic MiniLED value, but currently tops out at 75 inches, so if you want a truly massive screen, the TCL falls short. Sony's BRAVIA 5 delivers class-leading motion processing and accuracy, but again, the screen sizes are smaller and the price tag climbs fast. The LG's ace in the hole is that it hands you a 100-inch 4K panel with respectable HDR and low input lag without requiring you to sell your car.

Common Questions
Q: How many HDMI inputs does the LG QNED84B have?
It has four HDMI ports, and all of them support HDMI 2.1 with 4K 120Hz, VRR, and ALLM, so you can hook up a gaming PC, PS5, Xbox Series X, and a soundbar without any juggling.
Q: What is the refresh rate of the LG QNED84B?
The native refresh rate is 120Hz, which is perfect for sports, action movies, and high-frame-rate gaming with consoles or PCs.
Q: Is the screen mirroring feature available on this TV?
Yes, screen mirroring is built in through Apple AirPlay and Google Cast, and you can also mirror directly from a Windows PC or Android phone using the TV's built-in sharing support.
Q: Is the LG QNED84B good for gaming?
Absolutely, it's packed with gaming features like a 120Hz panel, FreeSync Premium, VRR, and ALLM, which combine for smooth, low-lag gameplay on current-gen consoles and PCs.
Who Should Skip This
If deep, inky blacks are a dealbreaker, skip this and snag a 77-inch OLED like the LG C3 or a Sony A80L instead. The QNED84B's MiniLED backlight can't match OLED contrast, and in a completely dark room, blooming is noticeable. Also, if you can't mount a 65.9 kg beast on your wall or you don't have the floor space, obviously look at a smaller TV. For anyone who needs a true 4K DCI cinema projector setup, a long-throw projector with an acoustically transparent screen will deliver better sound and pure black levels, but at a higher total cost and installation complexity.
Verdict
If your main goal is to fill a big wall with a sharp, colorful, and gaming-friendly image, the LG QNED84B is a solid yes. It's an enormous living room TV that handles 4K HDR content well, keeps gamers happy with fast refresh rates and low latency, and doubles as a smart home hub with all the AI voice assistants you could want. But if you're a stickler for absolute black levels, this isn't an OLED, and the blooming will bug you in a dark room. For die-hard cinephiles who watch mostly in complete darkness and won't compromise on contrast, look at an 83-inch OLED instead.
Movie nights with the family or watching sports with friends? The LG nails that experience. For the price you can pick it up for right now, it's one of the easiest ways to get a true theater feel without dealing with a projector's setup headaches.
