An evolution of OLED brilliance
Steadily evolved over the years, LG’s OLED evo panel takes an already ‘gold standard’ in TV technology and makes it better. OLED uses self-illuminating pixels for superb contrast and picture realism. Evo technology enhances this with an additional luminous element that makes the picture even brighter than before and the colour more vivid. For its combination of natural, lifelike images and vivid detail OLED evo is deeply impressive.
Transforming vision with Alpha 9 AI Processor Gen 8
Harnessing the power of AI, LG’s Alpha 9 AI Processor Gen 8 system introduces a raft of enhanced picture features. Settings such as AI Brightness, HDR Expression Enhancer and 4K Expression Enhancer let you fine tune the picture settings to your exact preferences, with more vivid colour, for example, when you want it, but not when you don’t. For the best picture, fuss-free, simply use the Auto Calibration setting.
Masterful with movies
If you’re mad about movies, you’ll love this LG’s incredible colour definition and cinematic realism. With its native 100Hz/120Hz display, brighter screen and host of HDR enhancements, including Dolby Vision, it delivers one of the most lifelike movie sensations that you’ll witness outside of the cinema. For the very best experience, Filmmaker Mode with Ambient Light Compensation lets you enjoy cinematic vision in all lighting conditions, exactly as the director intended, right down to using the correct aspect ratio, colour and frame rate.
The first choice for big-screen gaming
As well as being a top choice for movies, this LG OLED is also great for gamers. With a response time of less than 0.1ms, it’s super-fast to react to your every move. LG’s Game Optimiser gets you quick access to important settings. A selection of game genre presets lets you tailor the image to suit the game type. Compatible with 4K/144Hz refresh rates and featuring HDMI 2.1 sockets, it’s designed to get the very best from today’s games consoles. With support for Dolby Vision for Gaming, NVIDIA G-SYNC and AMD FreeSync, as well as ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate), you get to experience the smoothest and most responsive game play possible.
A sound AI advantage
LG’s powerful AI processing extends its benefits to sound as well as vision. With the AI Sound Pro and Voice Remastering settings, you get to experience a more lifelike sound and clearer dialogue. For a more immersive sound, Virtual 11.1.2 upmixing recreates a cinematic effect. Pair with an LG soundbar and the sophisticated WOW Orchestra processing splits the sound output between TV and soundbar, for a richer, more enveloping sound.
webOS 25 - the smartest operating system made even better
