How to watch on a computer
You need to purchase a subscription to watch live tennis streaming on Tennis TV. Tennis TV works well on both PCs and Macs.
Your Tennis TV subscription can also be used on mobile devices (iOS and Android) and a number of TV devices (Apple TV, Roku, Amazon Fire TV, XBox One, Samsung Smart TV and Android TV).
On computers and laptops, Tennis TV uses an HTML5 player. Flash is not required.
Most live matches and full replays are produced in true 1080p high-definition format. The streaming rates adapt to connection speeds up to 5 Mbps in HD, this is dependent on your connection and which device you are using. See this page for more information.
