- Dolby Vision and Dolby Atmos support built in 77th

What owners think
The Word on the Street
The proof
Performance
The gaming numbers are the real story here. A 0.1ms response time and 120Hz refresh rate put this in the 97th percentile for gaming, which is basically top of the charts. The α8 AI Processor 4K Gen3 does solid work, but the display and picture quality scores sit at 41st and 36th percentile respectively, so don't expect the brightness or color punch of LG's newer evo panels. It's fast, but it's not the brightest OLED in the room.

vs Competition
Against the Sony BRAVIA XR XR77A95L, the Sony wins on picture quality and brightness, but you'll pay a lot more for it. The TCL QM8K and Hisense U8 Series both get brighter and have better HDR punch, but they can't touch the OLED's perfect blacks or response time. If gaming is your main thing, the B6 holds its own. If you're mostly watching movies in a bright living room, the TCL or Hisense make more sense.

Value & Pricing
At $700 USD, this is a solid deal if gaming is your priority. You're getting OLED contrast and 120Hz for less than most mid-range LCDs. But if you care more about HDR brightness or movie watching in a bright room, save up for a newer OLED or a high-end QLED instead.

Overview
The LG OLED B6 is a weird mix of old and new. You get that gorgeous OLED contrast and a 120Hz panel that gamers will love, but the picture quality scores land in the middle of the pack compared to newer OLEDs. The one thing to know? This is a gaming beast first, a movie lover's dream second.
Common Questions
Q: Is this TV good for gaming?
Yes, it's one of the best gaming TVs for the price. The 0.1ms response time and 120Hz refresh rate mean no blur or tearing, and G-Sync plus FreeSync Premium cover both PC and console setups.
Q: Does it get bright enough for a sunny room?
Not really. OLEDs are known for perfect blacks, not peak brightness. If your room gets a lot of direct sunlight, you'll notice some washout. A brighter QLED like the TCL QM8K would handle that better.
Q: Do I need a soundbar?
Honestly, yes. The 2.0 channel speakers are fine for casual viewing, but Dolby Atmos through built-in speakers is more marketing than magic. A decent soundbar will make a huge difference.
Who Should Skip This
If you're buying a TV for a bright living room and mostly watch movies or sports during the day, this isn't it. The display brightness is mediocre and the picture quality scores are below average for OLEDs. Go get a TCL QM8K or Hisense U8 Series instead, they'll handle bright rooms much better.
Verdict
Buy the LG OLED B6 if you're a gamer who wants OLED contrast without spending a fortune. The 120Hz panel and 0.1ms response time are genuinely excellent, and at $700 it's a lot of TV for the money. Just know that the picture quality won't blow you away compared to newer OLEDs, and you'll want a soundbar to fix the weak built-in audio.
