A fast Internet connection is crucial for a smooth and high quality connection to everyone’s favorite streaming service. Netflix has one of the best mechanisms for streaming video over the Internet. So if you’re trying to stream something and it’s not quite in the 4K Ultra HD resolution you expected, it’s probably your Internet connection that’s responsible.

If you want to stream Netflix 4K Ultra HD content, you need not only a high definition TV, but also a fast Internet connection.

For a 4k stream, Netflix says you need an Internet speed of at least 25 Mbps. Most households in the United States probably do, but if you only pay for a cheaper service from your provider, your bandwidth may be close to this limit.

Many providers have a speed limit of 30 Mbps for their entry-level connections. If you are broadcasting something in SD, you only need 3 Mbps and 5 Mbps in Full HD, which means that streaming can take place while other people in your home are broadcasting a show in another room or playing a video game on your Internet connection. At 25 Mbps, you need most of your home’s bandwidth to stream 4k.

What do I need to stream Ultra HD in Netflix?

  • A 60Hz TV or computer monitor compatible with Netflix Ultra HD streaming. See below for more details.
  • A plan that supports Ultra HD streaming. On, you can check which plan you are on or update your plan.
  • A constant Internet connection speed of 25 megabits per second or more. See below for more details.
  • The stream quality is set to Auto or High. For more information on video quality settings, see our article on playback settings.

What is the speed of my Internet?

You can quickly check your Internet speed from one of the Internet Speed Test websites. However, note that these tests may not be correct if there are other factors that contribute to a slow network. See the next section below for more information.

Netflix has its own speed test on that you can use to test the speed of your network with Netflix. This is the best test if you plan to subscribe to Netflix because it tells you how much content you can download from their servers.


If you experience buffering and video problems with Netflix that fail to fully charge and amplify your WiFi signal, or if the Ethernet connection option does not solve the problem, stop using your other devices – you are probably making too many requests on your home network. If you have problems with video streaming, don’t download anything to your laptop and be on Facebook on your phone while streaming videos from your Xbox. It won’t work very well.
