onn 4K Pro Streaming Device vs Google Chromecast with Google TV (HD)

Buy the onn 4K Pro if you have a 4K TV, want Dolby Vision and Atmos, and need Ethernet or more headroom for apps. The Chromecast HD is the simpler pick for a 1080p set or a secondary TV, and its remote and interface are the same Google TV you get on the onn. The onn is the stronger box on hardware: 3 GB RAM, 32 GB storage, Wi-Fi 6 and a backlit remote with a remote finder. The Chromecast HD is smaller, runs on older Wi-Fi and tops out at 1080p, and owners report it can feel slow with heavy apps.

  • Choose the onn 4K Pro if your TV is 4K, you want Dolby Vision and Atmos, or you need a wired Ethernet connection.
  • Choose the Chromecast HD if you have a 1080p TV, want the smallest dongle, or need a cheap second streamer for a bedroom.

  • EthernetCriticisedReviewers note the wired port is limited to 100 Mbps rather than gigabit.
