On the main home page you are presented with a bunch of programs. Take this one for example. Click on the 3 dots. It will present you how you want to watch the program. Click the one you want (for example, last night, the NFL game was on Fox and on the NFL Network)


Click this dropdown. This will show you how you want to watch the show. It will bring up different ways to watch (like in 4K or in Spanish...)


Through here, you can select the 4K stream. This golf program doesn't support 4K so it's not showing up, but if it did, it would show up, and you would just click on it.


Hope this helps.
