Art Mode, which you might also see called Ambient Mode or Gallery Mode depending on who made the TV, is an idle setting that transforms your screen from a dead black rectangle whenever you’re not looking at it. Rather than the usual screensaver you’d see on existing TVs or streaming boxes when they’re idle, Art Mode aims to make your TV practically disappear into its surroundings. Here’s everything you need to know about the feature.

Even if you have a basic HDTV or streaming device, it probably has a screensaver option when you don’t have a movie or TV show playing. This is usually a slideshow of stock photos, scenic views, or personal photos that slowly pans across the screen to prevent burn-in.

Art Mode is a step up. The images don’t move, and the goal is to hide the fact that there’s a screen at all. Art Mode gives the impression of a painting hanging on a wall, complete with effects that eliminate glare and adjust to ambient light to maintain the illusion. You can still upload your images. They just look better in Art Mode than they do as a screensaver.

And while you’re taking photos, Art Mode also lets you do something extra tricky: you can send a photo of the wall behind the screen and make the device all but disappear. Art Mode can also include videos and non-paintings, but its main appeal is disguising your set as a decorative piece.
