The LG MRGB88 50" TV brings cinema-grade colour straight into your living room. Mini RGB evo technology uses ultra-small LEDs to reproduce 100% of the colours used by Hollywood, making everything look rich and lifelike. The α8 AI Processor works quietly in the background, boosting what you see and hear in real time. AI Super Upscaling sharpens lower quality content, while audio feels fuller and more cinematic. Plus, Precision Dimming uses multiple dimming zones to control light more accurately. Bright scenes stay vivid, while darker moments keep their detail.
