If this HDMI setting is turned off, it might ruin your TV’s picture quality

Chances are, if you have a newer TV, it supports HDR (High Dynamic Range), which greatly improves brightness and color when watching shows, movies, and playing games. Many streaming devices, like Fire TV Sticks, Apple TV, and Roku, support HDR, including formats such as HDR10+ and Dolby Vision. All the latest gaming consoles, including the PS5, Switch 2, and Xbox Series X, also support HDR.
