Whether you watch Netflix on your iPhone, iPad, Mac, or Apple TV, the quality of the video is determined by the speed of your Internet connection.
Netflix recommends 25 megabits per second (Mbps) of download speed for Ultra HD quality, 5 Mbps for HD, and 3 Mbps for SD – and 1.5 Mbps is the lowest recommended speed.
So how do you tell what your actual internet speed is right now? Visit Netflix’s fast.com Web site for a quick report on how much bandwidth you have. If what you see doesn’t match with what you think you’re paying for, call your Internet service provider and make sure your connection is working properly.
