77" 4K OLED Smart TV

This 77-inch television combines an OLED evo panel with the Alpha 11 AI processor Gen3 for self-lit pixels that deliver perfect black and accurate colour. The webOS 26 platform provides access to streaming apps, over 400 free LG Channels and more than 10,000 on-demand titles. It is suited to viewers who want a large-format display for movies, sport and everyday smart-TV use. Buyers needing a smaller screen or a non-OLED panel should consider other options.

webOS 26, AI assistants and Gallery+

The bundled webOS 26 interface adds Google Gemini and Microsoft Copilot voice control for content search and settings. LG Gallery+ lets you display artwork when the TV is idle, while Dynamic Sports overlays real-time statistics during live events. These software features change the set from a pure display into an interactive hub without requiring extra devices. Users who prefer a basic monitor without smart functions will not use these additions.

120Hz native refresh with G-Sync and FreeSync

The panel runs at a 120Hz native refresh rate and supports both NVIDIA G-Sync and AMD FreeSync Premium for tear-free gaming motion. Four HDMI ports and two USB 2.0 ports handle consoles, PCs and peripherals, while Wi-Fi and Ethernet give network flexibility. This specification makes the TV a strong match for high-frame-rate gaming. Buyers who only watch 60Hz broadcast content will not benefit from the higher refresh capability.

Questions about this item

Will the OLED panel's 8.3 million self-lit pixels need replacement or maintenance over time?

The OLED panel uses self-lit pixels that may experience gradual brightness reduction after extended use, but no user-serviceable parts or scheduled maintenance are required for the display itself.

What limits sustained 120Hz gaming performance on the HDMI inputs?

The four HDMI ports support 120Hz native refresh rate with NVIDIA G-Sync and AMD FreeSync Premium, so the panel's response time and VRR implementation set the practical limit during long sessions.

How much heat and fan noise does the Alpha 11 AI processor Gen3 produce when the TV runs all day?

The TV operates silently with no internal fans; heat from the processor and OLED panel is dissipated passively through the chassis, keeping noise at zero during continuous use.
