LG OLED77G5

The LG OLED77G5 marks a decisive milestone in the evolution of OLED TVs with its 77-inch Tandem OLED panel, a technological innovation that finally solves the complex equation between high brightness and energy efficiency. This 2025 model positions LG at the forefront of display technology by reaching brightness levels that were previously the preserve of Mini-LED screens, while retaining the intrinsic advantages of OLED: infinite contrast, absolute blacks, and near-instant response times.

Equipped with the α11 AI 4K Gen2 processor and the WebOS 25 interface enhanced with artificial intelligence, this TV caters to both demanding movie enthusiasts and gamers seeking ultimate performance. Its ultra-slim 24.8 mm thickness and wall-mounted design also make it a modern decorative piece that blends seamlessly into contemporary interiors.

Tandem OLED Innovation: Double Emission, Double Performance

The Tandem OLED panel is the technological heart of the G5, stacking two layers of organic emitters to double the brightness without compromising durability. This architecture achieves 2268 nits in Filmmaker mode on a 10% HDR window, and even 2300 cd/m² according to some tests, placing this TV on par with the best Mini-LED screens on the market.

The innovation goes beyond raw brightness: the Brightness Booster Ultimate technology optimizes light distribution pixel by pixel, delivering HDR rendering that stays true to creative intent. Full-screen brightness reaches 331 nits in Filmmaker mode, a 29% improvement over the previous G4. This technical progress is accompanied by a redesigned thermal management system that preserves the longevity of the organic components.

Picture Quality: Precision and Color Accuracy

The α11 AI 4K Gen2 processor orchestrates a suite of enhancement algorithms that analyze each image in real time. AI Picture Pro automatically adjusts settings based on content type, while AI Upscaling 4K transforms lower-definition sources with remarkable precision. Dynamic Tone Mapping Pro adjusts the tone curve frame by frame to optimize HDR rendering.

Color reproduction benefits from certification for 4K HDR content, ensuring compliance with Dolby Vision, HDR10, and HLG standards. Filmmaker mode, validated by the film industry, preserves the original artistic intent by disabling all unnecessary image processing. This fidelity makes the G5 a top choice for image professionals and movie lovers.

Gaming Performance: Maximum Speed and Smoothness

The G5 excels in gaming with a response time of 0.1 ms and a variable refresh rate reaching 165 Hz, surpassing the usual 120 Hz standard. This unique performance in the OLED market ensures broad compatibility with high-end gaming PCs and anticipates future generations of consoles.

Nvidia G-Sync and AMD FreeSync technologies eliminate screen tearing up to 165 Hz, while ALLM (Auto Low Latency Mode) automatically switches to gaming mode when a console is detected. Dolby Vision Gaming in 4K 120 Hz brings a cinematic dimension to compatible games, creating a stunning visual experience that enhances gameplay.

The built-in game optimizer offers genre-based presets (FPS, RPG, RTS) and displays real-time stats such as frame rate and latency. This holistic approach to gaming makes the G5 an optimal choice for demanding gamers, whether using next-gen consoles or high-performance PCs.

WebOS 25 and Integrated Artificial Intelligence

The WebOS 25 interface introduces a new generation of artificial intelligence that personalizes usage according to each user’s habits. The AI Chatbot answers questions about settings and guides image optimization based on the content being viewed. Hands-free voice control recognizes natural commands without the need for the remote.

Quick Cards provide direct access to the most-used functions, adapting the interface to individual preferences. Native integration of Google, Alexa, and LG ThinQ assistants allows you to control your entire smart home ecosystem from the TV. Apple AirPlay 2 and Google Cast compatibility make it easy to stream content from smartphones and tablets.

Design and Build: Elegance and Functionality

At just 24.8 mm thick, the G5 mounts on the wall like a painting, with a VESA 300x300 mount included. This native wall-mount design eliminates floor clutter but requires a separate stand purchase for furniture placement. LG’s choice to separate these elements optimizes the price for users who prefer wall installation.

The build prioritizes quality materials with an elegant gray finish that matches any décor. The weight of 33.6 kg without the stand is reasonable for a screen of this size, making installation easier. Integrated cable management in the wall-mount design preserves the overall aesthetic.

Audio: Decent Performance, Upgrade Recommended

The 4.2-channel, 60-watt audio system delivers acceptable sound for everyday use, with good voice clarity thanks to Clear Voice Pro processing. However, bass is limited by the TV’s ultra-slim design, and the lack of dedicated vertical speakers limits Dolby Atmos effectiveness.

AI Sound Pro processing virtualizes an 11.1.2-channel experience that improves spatialization but cannot overcome physical limitations. For demanding cinema or gaming use, adding a soundbar is recommended. The WOW Orchestra feature, however, allows you to combine the TV’s speakers with a compatible LG soundbar to enrich the soundstage.

Extensive Connectivity and Compatibility

The four HDMI 2.1 ports support 4K 120 Hz, eARC, VRR, and ALLM, covering all current and future needs. The eARC port on HDMI 2 ensures high-quality audio connection to external systems. Three USB 2.0 ports allow for multimedia playback and accessory connection.

Wireless connectivity with Wi-Fi 6 and Bluetooth 5.3 ensures stable and fast connections. Integration of major streaming services (Netflix, Disney+, Amazon Prime Video) with dedicated buttons on the remote simplifies content access. DLNA certification makes it easy to share content from other devices on the home network.

Supplied with a wall mount. Stand not included.
