Other things you might need to know

Now that you know the basics for how to set up a Chromecast, here are some other minor setup tips worth noting:

  • Many TVs have a USB port on the back and you might be tempted to cut down cord clutter and just plug your Chromecast into that for power. Even if you test it out and find that it supplies enough power for your Chromecast, it's not recommended because TV USB ports are notoriously unreliable and also your Chromecast will need to reboot every time you turn the TV on.
  • The Chromecast Ultra features an Ethernet port built into the power supply that you can use in lieu of a wireless connection. A wired connection might not be feasible depending on the location of your modem/router but it could be a better setup if you want to avoid buffering or stuttering video while streaming in 4K.
  • The Chromecast with Google TV has no ethernet port but charges via USB-C. You can connect a USB-C hub to your Chromecast with Google TV and plug in an ethernet cord from your router to the hub. This will not only give you a more consistent wired internet connection, but also lets you use power over ethernet (PoE), sparing you a power outlet.
  • Chromecast 3rd Gen owners should check out our list of the best ethernet adapters for Chromecast, which will work specifically with its micro-USB power cord.
  • Setting the proper room details for your Chromecast is especially important if you want to use Google Assistant to call up content since you'll need to specify the room when making your voice command. For example, you'd say "OK Google, play The Office on bedroom Chromecast".

Our top equipment picks

There are three Chromecasts currently available, though the Chromecast Ultra will only be available if you purchase a Stadia Premiere Edition package. The Chromecast with Google TV tops our best streaming devices round-up, and should undoubtedly be the first streaming dongle you consider.

The only exception would be if you just want a non-4K streaming dongle for a smaller TV in a spare bedroom, in which case you could save some money on the Chromecast 3rd Gen. Of course, we'd recommend taking the plunge and upgrading to 4K, so we've rounded up some of the best cheap 4K TVs for Chromecast users today.

The Chromecast with Google TV enables 4K streaming, gives you a remote control with Google Assistant built-in, and works for both casting and streaming, making it the best Chromecast you can buy if you're in the market for a new model.

If you're connecting to a non-4K TV and want to save some money, you're a prime candidate for a 3rd generation Chromecast.
