LG M-series OLED77M3PUA 77"

The LG M-series OLED77M3PUA is a 77-inch 4K OLED TV that uses a wireless Zero Connect Box to eliminate HDMI cables, delivering a stunningly clean wall-mounted setup. Gaming performance is best-in-class with 4K 120Hz and full VRR support. It's a niche luxury product that's perfect for cable-haters, but most people will get better picture quality for less money with a traditional wired OLED.

Gaming on this thing is an absolute treat. With a 120Hz refresh rate, near-instant 0.1ms response time, and support for both G-SYNC and FreeSync Premium, it's in the 98th percentile of our database for gaming. That puts it among the absolute best right now. The wireless connection doesn't introduce any noticeable input lag, which is frankly impressive. You can play fast-paced shooters or racers and it feels just as snappy as a wired OLED.

For movies and shows, the infinite contrast ratio delivers those perfect inky blacks OLED is famous for. The α9 Gen 6 processor does solid work upscaling lower-resolution content, and Dolby Vision support means you're getting the best possible HDR from streaming services. Brightness is handled by LG's Brightness Booster Max tech, which helps it hold its own in rooms with some ambient light, though it won't beat a high-end QLED in a sun-drenched living room. The built-in 4.2 channel audio with Dolby Atmos is well above average for a TV, landing in the 90th percentile. It's actually usable without a soundbar, which is rare.

The most direct competitor is the Sony BRAVIA XR XR77A95L. Sony's QD-OLED panel gets brighter and has better color volume, and its processing for movies is generally considered superior. But it's wired, and it's often more expensive. If pure picture quality is your goal, the Sony wins. The Samsung Neo QLED QN900F is another option if you're worried about brightness and burn-in, but you lose those perfect OLED blacks.

On the more budget-friendly side, the TCL QM7K Series and Hisense U7 Series are solid mini-LED TVs that cost way less. They won't touch the M3's contrast or gaming chops, but they're a much better value for casual viewing. The Roku Plus Series is even cheaper and simpler, but it's in a completely different league performance-wise. If you're considering the M3, you're specifically shopping for that wireless freedom, and none of these alternatives offer it.

Value is the trickiest part of the M3 story. At around $2,700, you're paying a hefty premium for the wireless tech. You can get a comparably sized LG C3 or even a G3 for less, and they'll deliver similar or better picture quality. But those TVs have cables. If a completely clean, wire-free wall is a priority for you, there's literally no other TV that does what this does. It's a luxury convenience product, and you have to decide if that convenience is worth the extra cash. For most people, a traditional OLED with some clever cable management will be the smarter buy.

The LG M-series OLED77M3PUA is one of those TVs that feels like it's from the future, mostly because of the Zero Connect Box. It's a 77-inch 4K OLED that beams video and audio wirelessly from a separate hub to the screen, so you can have a completely clean wall with no HDMI cables snaking up to the TV. If you've been searching for a high-end OLED TV with wireless connectivity, this is basically the only game in town. The panel itself is gorgeous, with the infinite contrast you expect from OLED, and it's powered by LG's α9 Gen 6 AI processor.

At this size and price point, which we've seen hovering around $2,700, you're squarely in premium territory. The TV comes with a dedicated wall mount designed to sit nearly flush against the wall, giving it that 'gallery' look. It's clearly built for people who care as much about their room's aesthetics as they do about picture quality. The 5-year panel warranty is a nice bit of peace of mind too, especially on such a big investment.

But the real story here is that wireless tech. The Zero Connect Box handles all your HDMI inputs and sends a 4K 120Hz signal to the screen with no perceptible lag in our testing. For gamers and home theater enthusiasts who hate cable clutter, it's a genuine breakthrough. Just know that you're paying a premium for that wireless magic, and you'll need to place the box somewhere within about 30 feet of the TV with a clear line of sight.

Skip the M3 if you don't absolutely need the wireless feature. If you have a standard media console under your TV or don't mind a single cable channel in the wall, you're better off with an LG G3 or a Sony A95L. Both deliver superior picture quality for less money. This is also not the TV for bright, sun-drenched rooms where a high-end QLED like the Samsung QN900F would fight glare much better. And if you're on a tighter budget, the TCL QM7K gets you a huge, capable screen for a fraction of the price.

Should you buy the LG M3? If you're remodeling a room and the thought of running HDMI cables through your wall makes you cringe, yes. This TV solves a very specific, very real problem for a certain type of homeowner. The wireless performance is genuinely impressive, and it doesn't compromise the gaming or viewing experience in any way we could detect.

But if you're just looking for the best picture quality for your dollar, look elsewhere. The M3's picture scores in our database are surprisingly average for an OLED, landing in the 36th percentile. That's not bad, but it's not what you'd expect for the price. You're buying the wireless tech first and the TV second. For everyone else, a wired LG G3 or Sony A95L will give you a better image for less money.
