LG G5 OLED evo TV: Features We Love

α11 AI Processor Gen2

LG’s most advanced processor yet, the α11 AI Gen2, takes everything you watch and makes it look its absolute best. With the help of AI, It’s clever enough to spot objects and faces on screen with pixel-perfect accuracy, upscaling visuals to stunning 4K clarity with richer colours and detail.

Next-Gen OLED Technology

We've always been fans of the latest tech and the LG G5’s Primary RGB Tandem OLED panel is something to get excited about. You can expect punchier colours, better brightness across the whole screen, and a more lifelike picture overall.

OLED, But Brighter Than Ever

OLED TVs have been getting brighter in recent years but the G5 sets a new bar. With LG’s Brightness Booster Ultimate onboard, you’ll get 3x brighter visuals than conventional OLED and 40% higher full screen brightness than last year’s G4.

How Does It Work?

Primary RGB Tandem OLED

Primary RGB Tandem OLED

A big change for this year is that the G5 moves away from the Micro Lens Array (MLA) technology used in the G4, and instead introduces a brand-new 4-Stack Primary RGB Tandem OLED panel. This new setup uses four light-emitting layers, including two blue, one red and one green to deliver brighter, punchier visuals and richer colours across the screen.

Why It’s A Big Deal: It takes everything we love about OLED and dials it up. Better brightness, more vibrant colours, and a picture that looks stunning any time of day.

Same Look, More Flexible

Prefer a Stand Mounted Setup?

Prefer a Stand Mounted Setup?

Available in 48", 55" and 65" sizes.
