For most TV models on the market, switching input signals often requires remote control or TV body buttons. Starting today, Xbox Series X|S users can use the controller to switch TV input signals.
According to media Gamespot, Xbox’s Larry Hryb announced that the feature is part of CEC, and game consoles using this feature can send commands to other devices (TVs) through their handles. CEC has been available on Xbox consoles for a while, but starting today, users can switch the TV’s input signal with the controller.
As long as the TV connected to the Xbox Series X|S supports CEC, players can use their Xbox controller to switch input signals. According to the Xbox official website, this function can be turned on in the power settings of the TV. After checking HDMI-CEC, click the circular watermelon button in the center of the handle, and the TV will switch to the signal input of the game console.
