LG 55" OLED EVO AI C6 4K Smart TV [2026]

The LG 55" OLED EVO AI C6 4K TV is a good fit for people who want deep contrast for movies and strong gaming support. It has a self-lit OLED screen, Brightness Booster and a 120Hz panel with four HDMI 2.1 inputs, plus NVIDIA G-Sync, AMD FreeSync Premium, Dolby Vision and Dolby Atmos.

OLED picture

This TV has an OLED screen where each pixel makes its own light and can switch off on its own, which means very deep blacks and strong contrast next to bright areas.

This TV has Brightness Booster, powered by the alpha 11 AI Processor Gen3, which is designed to lift brightness and detail. The processor also upscales lower-resolution content to suit the 4K screen, which means older shows and free-to-air TV fill the screen more cleanly. Results still depend on the source.

Gaming and connections

This TV has a native 120Hz refresh rate and four HDMI 2.1 inputs, which means smoother motion in supported games and room to plug in a console, a gaming PC and a soundbar without swapping cables.

This TV supports variable refresh rate (VRR) with NVIDIA G-Sync and AMD FreeSync Premium, which means less stutter and tearing when you're gaming on a compatible device. VRR runs from 40Hz up to 165Hz. This needs a compatible console or PC graphics card, compatible content and an Ultra High Speed HDMI cable, and the 165Hz mode is for PC-connected content.

It also has two USB ports, Ethernet, Wi-Fi 6E and Bluetooth 5.3.

Movies and sound

This TV supports Dolby Vision, HDR10 and HLG, which means movies and shows made in these formats have more detail in the bright and dark parts of the picture. Dolby Vision needs Dolby Vision content. It also has a 24 fps cinema mode for films.

This TV supports Dolby Atmos, though Dolby Atmos source content is needed for the full effect. It also has HDMI eARC, which means you can connect a compatible soundbar or AV receiver for bigger sound.

Smart TV and apps

This TV runs webOS, which means Netflix, Stan, Disney+, Amazon Prime, Kayo, Binge, YouTube, ABC iView and SBS On Demand are all in one place. Netflix, Stan, Disney+, Amazon Prime, Kayo and Binge require an additional subscription and internet connection at additional cost. Smart features need Wi-Fi and acceptance of LG's terms and privacy policies, and services may change.

This TV has Google Gemini built in, along with voice control, which means you can control the TV with your voice. It also has picture-in-picture, Google Cast and Apple AirPlay 2, which means you can watch two things at once or share content from your phone.

This TV has an HD tuner for free-to-air TV and can record or pause live TV to a USB storage device. Security updates are provided until 31 December 2030.

Size and wall mounting

This TV has a slim design with narrow bezels, which means the screen takes up most of the front of the TV.
