The aspect ratio will often be locked for certain content such as 4K and certain peripheral devices that play 4K content will also lock the content as 4K, even when the content isn’t 4K.

The Apple TV 4K, Chromecast Ultra, and certain Roku devices like the Roku Ultra all do this, among others. Additionally, some apps may also not offer the option to adjust the aspect ratio from the TV.

Another major reported issue is that the TV output may be stuck in wide aspect ratio mode on every input source, making it difficult to watch shows or movies comfortably. This could be due to the TV’s system software issue.
