Below are the Internet download speed recommendations per stream for playing movies and TV shows through Netflix.
HD Video Quality
Movies and TV shows that are available in high definition will play in 720p or better with a fast enough Internet connection. To watch Netflix in HD, ensure you have an HD plan, then set your video quality setting to High in the Playback Settings for your account.
Netflix Bandwidth Usage
Higher quality video uses more bandwidth than lower quality video. If your service provider applies a bandwidth or data cap to your Internet service, you can Manage Bandwidth Usage by changing the video quality settings to Low or Medium to consume less data.
