We welcome the day when TVs are invisible until we turn them on. Until then, there's Ambient Mode on 2018 Samsung QLED TVs. While in this semi-passive state, they can display information like weather or news, play music, and, most impressively, mimic the wall behind them, seeming to disappear into your room. They also have a single ultra-slim cable to connect both data and power, letting them hang up to 45 feet away from the nearest outlet, Direct Full Array backlighting for added contrast, and Bixby-powered voice control. Available in sizes ranging from 55 to 88 inches.
