Which Devices Can Chromecast Stream to?

Even though all of Google’s supported text for the device discussing connecting the dongle to the TV, the list of supported devices for Chromecast proves more extensive than what that implies. In order for Chromecast to work, the dongle requires a USB power supply and an HDMI connection.

  • HDMI Input: The HDMI connection supports any screen with an HDMI input. This includes modern HDTVs, smart TVs, PC monitors, projectors, and similar equipment. However, you can’t use a Chromecast dongle to cast content on a gadget with an output-only port.
  • Output-Only Ports Not Allowed: This means that game consoles like the Xbox series of devices, laptops, iOS mobile devices, Android devices, and so forth can’t make use of Chromecast to cast Netflix content from your TV to them.

  • Start the Cast: Launch Chrome, go to “More”, and then to “Cast”. A new Window should pop up that shows all the Chromecast devices (audio and video) available on your network. Click on a device, like the nearest HDTV with the dongle attached, to select it.
