TV Viewing Options
Every game of the 2017 NBA Finals will be airing exclusively on ABC. If you don't have cable, you can get a digital antenna and get all available local channels at zero monthly cost. A good option; my default. There's always the old stand by too of just going to a bar. No doubt every wing, pizza, and burger joint with a flat screen will be airing all games.
Online Streaming Options
WatchESPN. ABC and ESPN are a part of the same overall company (Disney), so to stream the games live, use the WatchESPN app. It works on several devices, our you can go straight to that link to stream live on your PC.
If you have a cable subscription, ABC also has a live stream app, but it's only available in certain markets. Use that link to see if you can stream. If so, it will work on your computer or any mobile streaming device, with login credentials.
If not, consider Sling TV. It runs for $20/month. And they give you a 7-day free trial, so you could essentially get up to 3 games streamed live for free if you time it right. Good service regardless though if you don't have any TV service subscription otherwise. Sling TV also gives you ESPN, a handle of cable channels, 23 channels in total.
NBA.com will also be updating the game in real time with their Series Hub page, including - highlight clips, scores, stats and more.
