Its built-in 213W audio system is a best-in-class powerhouse that outguns nearly every other TV. Just be ready to calibrate the picture, as its out-of-box accuracy is a disappointing 36th percentile.

The Word on the Street
The proof
Performance
This is where the G3 really struts its stuff. The α9 AI Processor Gen6 drives a 120Hz panel that's a gamer's dream. We're talking a 0.1ms response time, VRR, ALLM, and four full-bandwidth HDMI 2.1 ports. In our gaming benchmarks, it scored an 85.7 out of 100, putting it in the 97th percentile. Motion is buttery smooth, and input lag is virtually non-existent. It's one of the best gaming displays on the market right now.
The audio is another standout. The built-in 4.2-channel, 213W speaker system with Dolby Atmos support is a genuine powerhouse. It sits in the 99th percentile for audio, meaning it outclasses nearly every other TV's built-in sound. You can absolutely skip a soundbar for casual viewing, though a dedicated system will still give you more rumble. The smart platform is a solid webOS experience with hands-free voice control, sitting well above average in the 80th percentile.

vs Competition
Stacked against the Sony BRAVIA XR A95L, the LG G3 trades blows. The Sony typically wins on out-of-box color accuracy and picture processing, which explains the G3's lower picture quality percentile. But the LG fights back with superior brightness and a much better gaming feature set. The Samsung Neo QLED QN900F is a different beast entirely, using Mini-LED to get even brighter, but it can't touch the G3's perfect black levels and viewing angles. For pure gaming, the LG is the clear winner here. The TCL QM7K and Hisense U7 are fantastic budget contenders, but they don't play in the same league for build quality, audio, or that stunning flush-mount design.

Price
Value & Pricing
Value is a tricky word with this TV because the price is all over the map. We've seen it listed from $1,486 all the way up to $44,650, which is an absurd $43,164 spread. At the low end, this is a steal for a flagship OLED with this level of brightness and audio. At the high end, you're being taken for a ride. If you can snag it closer to that $1,500 mark, the price-to-performance ratio is phenomenal, especially when you factor in that you don't strictly need a soundbar. Just make sure you're buying from a reputable vendor with a solid return policy.

Overview
The LG G3 OLED is, simply put, one of the brightest OLEDs we've ever tested. It lands in the 90th percentile for display performance in our database, and that's largely thanks to the Brightness Booster Max tech. You're getting the perfect blacks OLED is famous for, but with a punch that actually holds up in a sunlit room. The 55-inch screen hangs flush to the wall with the included mount, making it look more like a piece of art than a TV. And with a 4.2-channel, 213W speaker system that sits in the 99th percentile for audio, it sounds as good as it looks.
But it's not a flawless victory. While the gaming chops are top-tier, landing in the 97th percentile with a 0.1ms response time and full HDMI 2.1 support, the picture quality score out of the box is a surprising 36th percentile. That means you'll want to spend some time calibrating it to get the most accurate image. The price also swings wildly between vendors, from $1,486 to a staggering $44,650, so shopping around isn't just a good idea, it's mandatory.
Common Questions
Q: How does the Brightness Booster Max feature enhance the viewing experience?
It's the secret sauce that pushes this OLED's peak brightness well beyond typical levels. In our database, this helps the G3 reach the 90th percentile for display performance, meaning HDR highlights pop with real intensity and the picture remains vibrant even in a well-lit room, which is a traditional weakness of OLED tech.
Q: Does this TV have built-in speakers?
Absolutely, and they're not an afterthought. It packs a 4.2-channel, 213W speaker system with Dolby Atmos. This setup ranks in the 99th percentile for audio in our tests, making it one of the best-sounding TVs you can buy without adding a soundbar.
Q: Is this TV good for gaming?
It's one of the best. With a 0.1ms response time, a 120Hz refresh rate, VRR, ALLM, and four HDMI 2.1 ports, it scored an 85.7 out of 100 in our gaming benchmarks. That puts it in the 97th percentile, meaning it delivers an incredibly smooth and responsive experience for both PC and console gaming.
Who Should Skip This
If you're a purist who demands a perfectly accurate picture right out of the box without touching a single setting, you should probably look elsewhere. The G3's 36th percentile picture quality score means its factory calibration is a real letdown. A Sony A95L will give you a more color-accurate image without the fuss. You should also skip this if you're on a strict budget, as the price can fluctuate into absurd territory, and a TCL QM7K will get you 80% of the performance for a fraction of the cost.
Verdict
The LG G3 is a phenomenal TV for gamers and cinephiles who want a bright, beautiful OLED that looks like a museum piece on the wall. The built-in audio is a genuine step above the competition, and the gaming performance is essentially flawless. The main caveat is that you should be prepared to tweak the picture settings or get it professionally calibrated to overcome its mediocre out-of-box accuracy. If you find it at a price near the lower end of its massive range, it's an easy recommendation.
