LG TV OLED evo AI G6 4K 2026, tech specs

The LG G6 is a flagship 4K TV featuring an OLED panel. As is common in modern TVs, it incorporates artificial intelligence; however, its role is fairly limited and mostly comes down to advanced software rather than true AI-driven image processing. In practice, AI is primarily used for user–server interactions, such as content recommendations, search, and voice control.

Image quality and display technology

The LG G6 is equipped with a 4K OLED panel with a resolution of 3840 × 2160. Brightness has been improved with Brightness Booster Ultra technology, making the TV approximately 20% brighter than the previous G5 generation. However, it is important to note that this increase applies only to specific scenes rather than the entire screen.

The display supports a 120 Hz refresh rate for video and gaming, and up to 165 Hz when receiving a compatible signal via HDMI. This is made possible by the display control hardware and the panel’s ability to operate at higher refresh rates without introducing visual artifacts.

Image processing

The LG G6 features the α11 AI Processor 4K Gen3, which is essentially a high-performance processor designed for premium TVs. It offers fast operation, solid graphics performance, and built-in image processing algorithms such as Super Upscaling 4K, allowing lower-resolution content to be effectively upscaled to 4K.

The TV supports key HDR formats, including Dolby Vision, HDR10, and HLG. Dynamic Tone Mapping Ultra further refines brightness and contrast on a scene-by-scene basis. Additional features such as Filmmaker Mode, which disables unnecessary post-processing, confirm that the TV includes the full set of standard premium-class capabilities.

Smart TV and gaming features

The LG G6 is well-suited for use as a gaming display. It supports VRR up to 165 Hz when connected to a compatible console or PC. NVIDIA G-Sync compatibility and ALLM ensure low latency by automatically optimizing settings. The Game Optimizer provides convenient access to gaming-related adjustments.

The TV runs on webOS 26, which is effectively the eleventh iteration of the platform. Despite updates to the interface design, the core system architecture has remained largely unchanged since 2021.

The TV includes built-in Google Cast and Apple AirPlay 2, along with support for Apple Home and Matter, making integration into a smart home environment straightforward. Hands-free voice control is also available.

Additional features such as Multi View, Always Ready mode, and AI Concierge improve usability. Connectivity options include four HDMI ports supporting 4K at 120 Hz, VRR, ALLM, and eARC, as well as USB ports, Bluetooth 5.3, Wi-Fi 5, and Ethernet.

Audio features

The LG G6 is equipped with a 4.2-channel speaker system with Dolby Atmos support, providing an immersive audio experience. The α11 AI Sound Pro feature upmixes audio into a virtual 11.1.2 surround format. However, achieving true high-quality surround sound requires a dedicated multi-speaker audio system.

Clear Voice Pro enhances dialogue clarity, while WOW Orchestra enables the TV speakers to work in synchronization with compatible LG soundbars.
