Chromecast is a streaming media adapter from Google that allows users to play online content such as videos and music on a digital television. The adapter is a dongle that plugs into a TV's High-Definition Multimedia Interface (HDMI) port. A power cable connects to a USB port on the Chromecast device. Chromecast devices enable users to stream (cast) content from their smartphones, tablets, laptops or desktop computers to a television with an available HDMI port. The newest generation of Chromecast -- Chromecast with Google TV -- extends these streaming capabilities by providing a user interface for running apps directly on the Chromecast device. Chromecast with Google TV also includes a Bluetooth remote that provides Google Assistant voice control. Earlier Chromecast models did not include the user interface or support local apps, nor did they provide a remote control. They were used strictly to stream content from other devices. Google no longer sells Chromecast devices without Google TV. Google currently offers two Chromecast with Google TV models. The first is the HD version, which can stream up to 1080p HDR, and the other is the 4K video resolution version, which can stream up to 4K HDR. The HD version costs $
