LG M-series LG M-series 77" 4K Ultra HD (3,840 x 2,160) 120Hz Review

The LG M3's wireless box lets you mount it cleanly with no cables to the screen. It's a top-tier gaming TV, but its overall picture quality is just average for the price. Worth it only if the wire-free install is your main goal.

The LG M3 is a TV that's trying to be a piece of art on your wall. It's a 77-inch OLED with a wireless box that sends all your video and audio signals to the screen, so you don't have to run cables up to the TV itself. That's the main trick here, and it's genuinely clever if you hate wires. And it's packed with LG's latest AI processor and all the gaming bells and whistles you'd expect from a flagship.

This thing is a beast for gaming, landing in the top percentile for speed and features. The 120Hz refresh rate, near-instant response time, and HDMI 2.1 support make it a dream for consoles or a PC. Picture quality is solid, but our data shows it's middle of the pack among OLEDs, not the absolute best. The HDR performance is strong, though. The audio is about average for a TV, so you'll likely want a soundbar.

This TV is expensive, and you're paying a premium for a specific feature: the wireless box and the super clean wall mount. If that's your main goal, it's worth it. But if you just want the best possible picture for your money, there are other OLEDs that score higher in our picture quality tests for less cash. The value is tied directly to how much you hate cables.

Compared to the LG C5, the M3's wireless box is the clear differentiator, but the C5 often has better picture scores for less money. The Sony BRAVIA 5 typically beats it in overall image processing and upscaling. Against a Samsung Neo QLED, you're choosing between OLED's perfect blacks and QLED's higher brightness. The M3 is the pick if your priority is a flawless, cable-free wall installation over absolute picture perfection.

Skip this if you're just looking for the best picture money can buy. Our data shows other OLEDs rank higher for pure image quality. Also, if you don't plan to wall-mount your TV, the M3's main feature is pointless, and you're paying extra for a box you'll just hide in a cabinet anyway.

Buy this if you're designing a minimalist media room and the dream is a TV floating on the wall with zero visible wires. The wireless box and included mount deliver that perfectly, and the gaming chops are fantastic. But if you're just shopping for the best 77-inch OLED picture quality, other models might serve you better.
