Display Performance: OLED Excellence at Its Peak

The M5’s 77-inch 4-stack WOLED panel delivers the infinite contrast characteristic of OLED technology, with absolute blacks and optimized brightness thanks to the Brightness Booster Ultimate. Each pixel turns off individually, creating a level of contrast impossible to reproduce on traditional LCD technologies. This capability is particularly striking when viewing cinematic content with dark or high-contrast scenes.

The Alpha 11 Gen2 processor orchestrates sophisticated image processing with AI Picture Pro, analyzing each frame in real time to optimize sharpness, colors, and HDR tone mapping. 4K upscaling transforms lower-resolution content with remarkable precision, while Object Enhancement technology specifically identifies and enhances faces, text, and foreground elements.

Extensive HDR format compatibility—Dolby Vision, HDR10, HLG, and HDR10+—ensures faithful reproduction of artistic intent. Filmmaker Mode automatically disables processing that could alter the director’s original vision, respecting the professional calibration of cinematic productions.

The native 120Hz refresh rate, extendable to 144Hz via VRR, guarantees exemplary smoothness for all types of content. This capability is especially beneficial for sports, nature documentaries, and fast-paced action sequences where every movement detail matters.

Cutting-Edge Gaming: Uncompromising Performance

The M5 stands out as a gaming reference with its native 144Hz refresh rate and 0.1 ms response time. This exceptional responsiveness virtually eliminates any lag between player action and display, a decisive advantage for competitive and fast-paced games. Triple compatibility with G-Sync, FreeSync, and HDMI VRR (40-144Hz) ensures perfect synchronization with NVIDIA and AMD graphics cards.

Dolby Vision Gaming is an industry first, applying the benefits of dynamic HDR to video games in 4K 120Hz. This technology analyzes each game scene to automatically optimize brightness, contrast, and colors, revealing invisible details in dark areas while preserving interface readability.

Auto Low Latency Mode (ALLM) automatically detects game signals and instantly activates optimized settings, while Quick Media Switching (QMS) eliminates black screens during refresh rate changes. The built-in gaming optimizer offers genre-specific presets—FPS, RTS, RPG—allowing quick adjustment according to game type.

Full compatibility with PlayStation 5 and Xbox Series X ensures maximum exploitation of their technical capabilities. The HDMI 2.1 ports on the Zero Connect box support the bandwidth required for 4K 120Hz with VRR, without limitation or compression.

Integrated Artificial Intelligence: Personalization and Optimization

The webOS 25 system integrates advanced artificial intelligence features that transform daily interaction with the TV. AI Sound Pro automatically analyzes audio content to adapt sound settings: enhanced dialogue for movies, spatialization for music, or gaming optimization for games. This adaptation happens seamlessly, without user intervention.

Voice search benefits from improved contextual understanding, allowing natural requests like “find me recent action movies with Keanu Reeves” or “play the latest episode of my series.” Google, Alexa, and LG ThinQ assistants are natively integrated, offering full voice control without a remote.

The recommendation system analyzes viewing habits to suggest personalized content across all connected platforms. This intelligence extends to automatic recording scheduling and optimized energy management based on usage times.

AI Picture Pro adapts to ambient lighting conditions detected by built-in sensors, automatically adjusting brightness and color temperature for optimal visual comfort. This feature is especially appreciated during long viewing sessions or changes in natural lighting.

Design and Ergonomics: Functional Elegance

The remarkable 2.48 cm thickness gives the M5 a discreet presence that blends harmoniously into any interior. This slimness, characteristic of OLED technology, allows for an almost flush wall installation, creating a striking “digital painting” effect. The light weight of 35.5 kg makes handling and installation easier compared to LCD TVs of equivalent size.

The included central stand ensures optimal stability while minimizing floor space. Its design allows limited rotation to adjust the viewing angle according to listening position. VESA 300 x 300 compatibility offers a wide choice of wall mounts, from simple articulated arms to motorized systems.

The matte black finish eliminates unwanted reflections and keeps attention on the displayed image. This understated aesthetic naturally fits contemporary environments without creating a distracting focal point.

The Magic Remote evolves with an improved ergonomic design and intuitive gesture functions. The on-screen pointer makes navigating complex menus easier, while the central wheel allows precise control of volume and settings. The integrated voice command saves you from searching for the remote for common actions.

Connectivity and Ecosystem: Central Multimedia Hub

Beyond the Zero Connect revolution, the M5 integrates perfectly into connected home ecosystems. Compatibility with Apple HomeKit, Google Home, and Matter makes it easy to integrate into existing smart home routines. The TV can thus turn on automatically when you return home or turn off according to scheduled times.

Wi-Fi 6 (802.11ax) and Bluetooth 5.2 ensure high-performance connectivity with all home devices. 4K streaming is smooth and buffer-free, even on busy networks. The multi-screen function allows you to display up to four different sources simultaneously, handy for following multiple sports events or monitoring security feeds.

Native AirPlay 2 and Google Cast make it easy to share content from smartphones and tablets. Streaming quality reaches 4K HDR without degradation, turning the TV into a natural extension of mobile devices. Multi-room audio synchronization with compatible speakers creates a coherent sound environment throughout the house.

Pre-installed apps cover all popular platforms: Netflix, Disney+, Prime Video, Apple TV+, YouTube, as well as cloud gaming services Xbox Cloud Gaming and GeForce Now. This native integration avoids the need for multiple external boxes and simplifies the user experience.

Audio and Sound: Solid Yet Improvable Foundations

The 4.2-channel 60W audio system delivers respectable quality for everyday use. The built-in subwoofer provides appreciable bass, while the front speakers ensure good dialogue intelligibility. Dolby Atmos compatibility creates a semblance of sound spatialization, though limited by the physical configuration of the drivers.

AI Sound Pro automatically adapts settings according to detected content. Dialogues benefit from intelligent enhancement, music from stereo expansion, and sound effects from increased dynamics. This optimization is particularly effective for TV programs and streaming content.

The WOW Orchestra function allows synchronization with compatible LG soundbars, creating a unified audio system. This technology simultaneously uses the TV’s and soundbar’s speakers for a more immersive sound. Automatic calibration adjusts delays and levels to optimize sound coherence.

For dedicated cinema use, investing in an external soundbar is still recommended. The built-in 60W reaches its limits when reproducing complex soundtracks or high-dynamic content. The eARC on the Zero Connect box ensures compatibility with all high-end external audio systems.
