Google begins to introduce 4K streaming support for Stadia on the Internet. 9to5Google reports that a number of Reddit users have discovered new 4K support in games like Assassins Creed Odyssey, Mortal Kombat 11, and Grid. However, the option does not appear to be available to all Stadia users. We tested three Stadia accounts and none of them currently have the 4K option.
If you're a Stadia user, you can check the connection quality and resolution by pressing Shift + Tab after starting a game and selecting the connection section. A 4K label should appear if your connection and display support the new streaming option.

It's still not clear how Google processes 4K streams over the Internet on devices with 1080p or 1440p screens. If Google needs a 4K monitor and hasn't implemented downscaling for Stadia on the web, many users will be excluded from this new option. We will test this completely as soon as the 4K option appears on our Stadia test accounts.
Google also appears to be preparing new features for Stadia. A current Stadia app indicates the highly anticipated free level, YouTube streaming, sharing family games and much more.
