Sentiment Score 86%LG’s new OLED77ZX has a 75-77-inch screen. This makes it less expensive than the £30,000 OLED88Z9. It also gets a less premium design with its slim black frame, metallic silver outer trim, flat back panel. It doesn’t ship with a slot-in floorstand like the 88-inch model does, and is significantly chunkier around the back.
