LG OLED evo AI G5 4K  – Brightness Booster Ultimate, α11 AI Processor Gen2 & 144Hz Gaming

The LG OLED48G5 is the 48-inch model in LG's 2025 OLED evo G5 series — a gallery-designed 4K OLED TV built for people who want reference-level picture quality in a smaller, wall-hugging form. With over 8.3 million self-lit pixels, Brightness Booster Ultimate, LG's most powerful α11 AI Processor 4K Gen2, and a 5-year panel warranty, it delivers perfect black and perfect colour with the brightness to handle a bright room.

Brightness Booster Ultimate — Remarkably Luminous Detail

Brightness Booster Ultimate magnifies each individual pixel for remarkably luminous detail, while Bright Room Ready performance means the G5 looks great no matter the room or the lighting. LG's internal testing rates Brightness Booster Ultimate as significantly brighter than the entry B5 series, and the panel carries UL-certified Glare Free validation — a meaningful advantage for living rooms with large windows or afternoon sun.

OLED's Perfect Black, Perfect Colour

With OLED's over 8.3 million self-lit smart pixels, each pixel switches on and off independently — so blacks are truly black, not grey, and colours stay accurate at any viewing angle. OLED Colour wide colour gamut and Pixel Dimming deliver precise contrast in shadows and highlights, and OLED Dynamic Tone Mapping Pro refines HDR scene by scene.

LG's Most Powerful AI Processor — α11 AI Processor Gen2

The α11 AI Processor 4K Gen2 powers a personalised experience with spectacular picture and sound through AI Picture Pro and α11 AI Super Upscaling 4K. AI Sound Pro (Virtual 11.1.2 Up-mix) and AI Acoustic Tuning adapt audio to your room, while the Personalised Picture & Sound Wizard analyses your favourite images and clips to tailor settings to your taste.

Movie Magic from home — Dolby Vision, Dolby Atmos & FILMMAKER MODE

Enjoy movie magic from home with Dolby Vision, Dolby Atmos, and FILMMAKER MODE™ — preserving the director's original colour, contrast, and frame rate. AI Director Processing tunes tone mapping to film content, and a 2.2-channel, 40W speaker system with Clear Voice Pro and WOW Orchestra (with compatible LG soundbars) delivers convincing built-in audio.

Ultimate Gaming — 144Hz, G-Sync and FreeSync Premium

The 48-inch G5 supports VRR up to 144Hz with a native 120Hz panel and less than 0.1ms response time. NVIDIA G-Sync Compatible, AMD FreeSync Premium, ALLM, HGIG, and Dolby Vision for Gaming at 4K 120Hz are all supported, and all four HDMI ports handle 4K 120Hz, eARC, VRR, ALLM, QMS, and QFT. The Game Optimiser with Game Dashboard puts everything in one place, and the LG Gaming Portal plus Xbox app enable cloud gaming without a console.
