The 30-Second Version
A 77-inch OLED gaming god with a picture quality problem. Buy it for the speed, not the cinema.
Overview
The LG B6 is a bit of a paradox. It's a massive, gorgeous 77-inch OLED that delivers some of the best gaming performance we've ever seen, but it stumbles in a way we didn't expect for a premium 2026 TV. The picture quality score in our database is surprisingly mediocre, landing in the 37th percentile. That's not a typo. So, the one thing to know is this: if you're a hardcore gamer who wants a huge screen with near-instant response times, keep reading. If your main priority is the absolute best movie-watching picture for the money, you might want to pump the brakes.
Performance
The gaming chops on this thing are genuinely shocking. A 0.1ms response time and a 120Hz panel put it in the 98th percentile for gaming, which is basically the top of the charts. It's buttery smooth with both FreeSync Premium and G-Sync on board. But then we look at the overall picture quality score, and it's a real head-scratcher. Despite having an OLED panel with perfect blacks and Dolby Vision, our testing shows it falls behind most of the competition in pure picture fidelity. It's like LG built a world-class gaming monitor and forgot to give it the flagship TV picture processing it deserves.
Pros & Cons
Pros
- Best-in-class gaming performance with a 0.1ms response time. 98th
- Infinite contrast ratio delivers those perfect OLED blacks. 97th
- Four HDMI 2.1 ports is a connectivity standout. 88th
- webOS 26 is a genuinely smart and snappy platform. 85th
Cons
- Overall picture quality is a weak spot, scoring in the 37th percentile. 9th
- The built-in 2.0 channel audio is underwhelming for a TV this size.
- No customer reviews yet, so you're buying on faith.
- Price swings wildly by over $1,000 between vendors.

Value & Pricing
With prices ranging from $2,800 to $3,865, you absolutely need to shop around. That's a $1,065 spread, which is insane. The best deal we're seeing is at Best Buy, so don't pay a penny more than their price. At the low end, you're getting a massive 77-inch OLED gaming beast, which is a solid value. At the high end, you're getting ripped off. Simple as that.
Price History
vs Competition
The obvious competitor is the Sony BRAVIA 9 K85XR90. Sony's processing will almost certainly smoke the LG in picture quality, which is this B6's glaring weakness. You'll trade some of that elite gaming speed for a much better movie experience. On the other end, the Hisense U8QG Mini-LED gives you a 100-inch screen for a similar price. You lose the per-pixel OLED contrast, but you gain a ton of screen real estate and likely much brighter HDR highlights. The LG sits in a weird middle ground: it's the gamer's choice, but not the cinephile's.

Common Questions
Q: Is this TV good for a bright room?
It's decent, but not the best. OLEDs have gotten brighter, but a high-end Mini-LED TV like the Hisense U8QG will fight glare much better. The LG's strength is in a light-controlled room where those perfect blacks can really shine.
Q: Does it support 4K at 120Hz on all HDMI ports?
Yes, all four of its HDMI ports are the full-fat 2.1 variety. That's a huge plus and better than most competitors that only give you two. You can have a PC, PS5, and Xbox Series X all plugged in at once without swapping cables.
Q: What's the deal with the 'OLED Care' feature?
It's LG's system to prevent burn-in. It does things like pixel shifting and screen refreshing when the TV is off. It's not something you'll notice day-to-day, but it's essential for keeping that OLED panel looking good for years.
Who Should Skip This
If you're looking for the absolute best picture quality to watch 4K Blu-rays and stream movies, this isn't it. The processing just isn't there. Go get a Sony BRAVIA 9 instead. You'll lose a tiny bit of gaming speed but gain a massively better cinematic picture.
Verdict
The LG B6 is a niche champion. We can only recommend it without hesitation to one specific person: a gamer who wants a gigantic OLED and prioritizes response time and smoothness above all else. For everyone else, especially movie lovers, the poor picture quality score is a dealbreaker. You can get a better all-around viewing experience from Sony, or a much bigger screen from Hisense for the same cash. This is a specialist's tool, not a crowd-pleaser.
