Snapshot

The 30-Second Version

The LG UA77 Series 86UA7700PUA is an 86-inch 4K TV built for size and smart features on a budget. It delivers a good streaming experience and massive screen real estate, but its picture quality and 60Hz panel fall short for home theater fans and serious gamers. Buy it for the sheer scale and excellent webOS platform, not for top-tier performance.

The proof

Performance

Let's talk about what the Alpha 7 AI Processor Gen8 actually does for you. It handles 4K upscaling and dynamic tone mapping, which helps clean up lower-resolution content on this giant canvas. The picture is vibrant enough for a bright room, and the smart features are snappy. But the panel itself is a 60Hz direct LED with no local dimming. That means black levels are more of a dark gray, and you won't get the punchy HDR highlights you'd see on a set with full-array local dimming or Mini-LEDs. In our database, the picture quality lands in the 37th percentile, which is frankly mediocre. The HDR performance is a bit better at the 62nd percentile, but it's still just a middle-of-the-pack experience. For gaming, the 60Hz panel and HDMI 2.0 ports mean you're capped at 4K 60fps. It supports VRR and ALLM to keep things smooth, but serious gamers will feel the lack of 120Hz and HDMI 2.1 bandwidth. The built-in 2.0 channel audio is another weak spot, ranking in the 46th percentile. It's fine for news, but you'll absolutely want a soundbar for movies.

vs Competition

The LG UA77's main rivals are all about giving you more tech for a bit more cash. The TCL QM8K Series is the most direct threat. It uses Mini-LED backlighting for far better contrast and brightness, and it runs at 120Hz for smoother gaming. The Hisense U8 Series is another strong alternative in the same vein, often packing a high refresh rate and quantum dot color for a more vibrant HDR experience. If you want to stick with a big name, the Samsung Neo QLED QN70F will give you a noticeably sharper, brighter picture with deeper blacks, though you'll pay a premium for it. The LG's main advantage over all of them is simply being the cheapest way to get an 86-inch screen from a reputable brand with a smart platform people genuinely love. It's a size-first, quality-second proposition.

Price

Value & Pricing

Value is where this TV makes its strongest argument. With a price range spanning from $450 to $1089 across vendors, you can snag an 86-inch screen for less than a 65-inch OLED from a premium brand. That's the whole pitch. The best deal in our data comes from Best Buy, so that's where we'd point you first. You're trading picture excellence for square footage, and for a lot of people, that's a fair trade. If your main goal is to fill a big wall with a good-enough 4K picture for streaming shows and sports, the cost-per-inch here is tough to beat. Just know that spending a few hundred more on a competitor like the TCL QM8K gets you Mini-LED backlighting and a 120Hz panel, which is a massive leap in performance for not a massive leap in price.

Overview

If you're hunting for a massive screen that won't demolish your bank account, the LG UA77 Series 86UA7700PUA is probably on your radar. This 86-inch 4K LED TV is all about sheer size for the dollar. It's a 2025 model that skips the fancy OLED or Mini-LED tech for a straightforward direct-lit panel, powered by LG's Alpha 7 AI Processor Gen8. You get the full webOS smart platform, HDR10 and HLG support, and a handful of gaming features like FreeSync and VRR, all wrapped in a package that's clearly aimed at living rooms where bigger is better. For streaming and smart home integration, this thing is a champ, landing in the 98th percentile in our database for both categories. But you're making some clear trade-offs to hit that price point, especially in raw picture quality and audio performance, which sit well below average compared to other TVs we've tested.

Common Questions

Q: Is the LG UA77 good for gaming?

It's decent for casual gaming with FreeSync, VRR, and ALLM support, but the 60Hz panel and HDMI 2.0 ports mean you can't play at 4K 120fps on a PS5 or Xbox Series X.

Q: Does the LG 86UA7700PUA have good picture quality?

The picture quality is just average for a 4K TV. It's bright and colorful enough for everyday viewing, but the lack of local dimming results in grayish blacks and unremarkable HDR performance.

Q: What is the LG UA77 webOS Re:New program?

LG's Re:New program guarantees software updates and new features for the TV's webOS smart platform for up to five years, so the interface won't feel outdated quickly.

Q: How does the LG UA77 compare to the TCL QM8K?

The TCL QM8K is a step up in picture quality thanks to its Mini-LED backlight and 120Hz panel, offering much better contrast and gaming performance, but the LG UA77 is typically cheaper at the 86-inch size.

Who Should Skip This

Home theater enthusiasts and serious gamers should skip this one. If you notice blooming, crave inky blacks, or want to play games at 4K 120fps, the LG UA77's direct LED backlight and 60Hz panel will disappoint you. You're better off saving a bit more for a Mini-LED set like the TCL QM8K or Hisense U8 Series, or even dropping down to a 75-inch model with better tech. This TV is also a poor fit for a dark, dedicated media room where its weak contrast will be most obvious.

Verdict

Should you buy the LG 86UA7700PUA? If your number one priority is getting the biggest possible screen for the least amount of money, and you're not a stickler for deep blacks or high-frame-rate gaming, then yes, absolutely. It's a crowd-pleaser for a bright family room where you mostly watch cable, YouTube, and streaming sitcoms. The webOS platform is fantastic, and the sheer scale of the thing is impressive for the price. But if you care about picture quality, even a little bit, you should look elsewhere. The lack of local dimming and a 120Hz panel makes this a non-starter for home theater enthusiasts or anyone with a modern gaming console they want to push to its limits. This is a quantity-over-quality champion, and as long as you know that going in, you'll be happy with it.
