The LG G5 77 inch is a beast. Honestly, it’s the TV most of us have been waiting for since Micro Lens Array (MLA) tech first leaked out of LG Display’s labs. But let’s get one thing straight right away: calling this just another "incremental update" is a flat-out lie. If you’ve been staring at a C-series OLED for the last five years, walking into a room with a 77-inch G5 is going to feel like someone finally turned the lights on.
It’s bright. Really bright.

We’re talking about peak brightness levels that finally rival high-end Mini-LED sets, but without that annoying blooming you see when a white subtitle hits a black background. LG’s 2026 flagship lineup, specifically this G5 model, represents the second generation of their massive "Brightness Booster Max" push. It isn't just marketing fluff. It’s physics. By using billions of microscopic lenses—literally billions—the panel redirects light that used to get trapped inside the glass straight into your eyeballs.
Why the LG G5 77 inch is Dominating the 2026 Market
People kept saying OLED had hit a ceiling. They were wrong. The LG G5 77 inch proves that the ceiling was actually a floor. The big story here isn't just the size, though 77 inches is arguably the "sweet spot" for high-end home theaters. The real story is the Alpha 11 AI Processor Gen 2.
It’s fast. Like, frighteningly fast.
The silicon inside this chassis does things with upscaling that make 1080p content look like it was shot yesterday in 4K. If you’re a fan of older cinema or just watching sports on a bitrate-starved streaming app, you’ll notice the difference in about three seconds. The banding is gone. That weird "noise" in dark scenes? It’s smoothed out without making everyone’s faces look like they’re made of wax.
The MLA 2.0 Breakthrough
Last year’s G4 was impressive, but the LG G5 77 inch refines the Micro Lens Array structure to a point where efficiency has skyrocketed. Basically, the TV produces more light while using less power per nit. This is huge for longevity. Heat is the enemy of OLED. By being more efficient, the G5 runs cooler, which theoretically pushes the risk of permanent image retention (burn-in) even further into the realm of "stop worrying about it."
I’ve seen side-by-sides with the Samsung S95F QD-OLED. It’s a tight race. Honestly, Samsung still wins on color volume—those reds just pop differently—but the LG G5 wins on "natural" realism and shadow detail. If you want a movie to look like the director intended, you go LG. If you want it to look like a candy store, you go Samsung. Both are valid. But for the purists? The G5 is the king.
Design and the One Wall Bracket
Let's talk about the physical unit. The LG G5 77 inch is thin. Impossibly thin. It’s designed to sit flush against your wall using the proprietary bracket included in the box. If you want to put this on a stand, you’re going to have to pay extra. That’s been the G-series tax for years, and it still stings.
The bezel is almost non-existent. When it’s off, it looks like a piece of dark glass. When it’s on, the image just floats.
- No bulky "backpack" for the electronics.
- Uniform thickness across the entire back.
- Integrated cable management that actually works (unlike some rivals).
Gaming on this thing? It’s a dream. We’re looking at four full-bandwidth HDMI 2.1 ports. 144Hz VRR support is standard now. Whether you’re hooked up to a PS5 Pro or a high-end PC rig with an RTX 50-series card, the input lag is virtually non-existent. You click, it happens.
The webOS 26 Experience
Software is usually where these TVs fall apart. LG’s webOS has had its ups and downs. In the LG G5 77 inch, webOS 26 feels... leaner. They’ve finally toned down the intrusive ads, though they aren't completely gone. You can actually customize the home screen now without needing a degree in UI design.
The "Quick Cards" feature is legitimately useful. You can jump to your gaming hub or your smart home dashboard without exiting whatever movie you’re watching. It’s smooth. No stutters. No weird crashes.
The Elephant in the Room: Price vs. Performance
Is it expensive? Yeah. You’re paying for the peak of display technology. But here’s the thing: the 77-inch model is the one to get because it’s where the MLA tech really shines. On the smaller 55-inch, the density is great, but at 77 inches, the sheer scale of that brightness makes your living room feel like a commercial IMAX theater.
Is it worth upgrading from a G3 or G4? Probably not. Unless you’re a spec-head who needs the absolute latest. But if you’re coming from a C1, a CX, or—heaven forbid—an old LED TV? The LG G5 77 inch will be the best thing you’ve ever bought for your house.
The sound is also surprisingly decent. Most thin TVs sound like a tin can in a tunnel. LG uses "AI Sound Pro" to virtualize a 11.1.4 channel setup. Look, it’s not going to replace a dedicated Sonos system or a proper wired 7.2.4 rig. But for watching the news or a casual Netflix sitcom? It’s punchy and clear. The voices don't get buried in the mix.
Real World Limitations
Nothing is perfect. The LG G5 77 inch still has a glossy screen. While the anti-reflective coating is better than it was three years ago, if you have a massive window directly opposite the TV, you’re going to see your reflection during dark scenes in The Batman.
Also, LG still refuses to support HDR10+. They are strictly Team Dolby Vision. Most people won’t care because Dolby Vision is the industry standard for streaming, but if you’re a collector of physical 4K Blu-rays that use HDR10+, you’re stuck with base HDR10. It’s a minor gripe, but for a TV at this price point, we should have everything.
Comparison: G5 vs. C5
The gap between the C-series and the G-series has widened. In the past, they used the same panels. Not anymore. The C5 is a great TV, but it lacks the MLA hardware. If you put them side-by-side, the LG G5 77 inch is noticeably more vibrant. It has more "depth." It’s the difference between looking at a photograph and looking through a window.
- Check your wall studs. A 77-inch TV is heavy. The G5 is built like a tank.
- Buy high-quality cables. Don't spend $4,000 on a TV and use a $5 HDMI cable from 2012. You need 48Gbps bandwidth.
- Calibrate the "Filmmaker Mode." It’s the most accurate setting out of the box. Turn off the "Energy Saving" mode immediately—it kills the brightness you paid for.
The LG G5 77 inch represents the maturity of OLED. We've moved past the era of "OLED is too dim for bright rooms." With the G5, that argument is dead and buried. This TV can handle a sun-drenched Florida living room and still look spectacular.
If you're looking for the absolute pinnacle of 2026 display tech, this is it. It’s a refined, powerful, and visually stunning piece of engineering that makes every other screen in your house look like a calculator display.
Actionable Next Steps
- Measure your viewing distance: For a 77-inch 4K screen, you want to be sitting between 7 and 10 feet away to get the full immersive effect without seeing individual pixels.
- Check your mounting situation: Since the G5 is designed for flush-mounting, ensure your recessed power outlets and cable runs are positioned centrally behind where the panel will sit.
- Audit your streaming subs: To actually see what the LG G5 77 inch can do, make sure you're paying for the "Ultra HD" tiers of Netflix and Max; otherwise, you're feeding a Ferrari low-grade fuel.
- Compare prices at local retailers: While MSRP is high, LG frequently runs "Buy a G-series, get a free soundbar" promotions in the second quarter of the year. It’s often worth waiting for those holiday bundles.
