Streaming video sites and services allow you to change the quality of the stream. You might think you always want to choose the best/highest quality, but doing so may result in stuttering. You may find that a small decrease to 720P or 480P still looks very similar in your browser but will load much faster. Here are some recommended settings for popular streaming services :
