The Chromecast with Google TV 4K is getting a great new feature from ... Android 12? Yes, that might sound odd — Android 13 dropped in August, mind you — but one of the added features of this update is great for film-lovers and anyone who wants their streaming to look correct.

As FlatPanelsHD notes, the fine print for this update includes "New! Match content frame rate allows you to switch between refresh rates." This is huge for anyone who thinks movies just don't look right on the Chromecast.

If you've ever noticed that the motion in movies just doesn't look right, that might be because of something called judder. This is due to streaming devices rendering films at the wrong framerate, though your streaming service of choice has to be able to provide the movie at the right framerate.

Analysis: Why this matters

Without this setting, 24fps films are often delivered incorrectly, partially because you can't divide 60 by 24 evenly. As HowToGeek explains, this causes one frame of a film to display for two refreshes and a subsequent frame to display for three seconds.

This incorrect and uneven pattern makes movies look wrong, and it's called "juddering." This shouldn't be confused with stuttering video, but it's the kind of flaw that's slowly being removed.

So, when you're watching a movie or show with a slow camera pan, say No Country For Old Men, you'll probably notice uneven motion as the camera moves across a plane.

Other Android 12 updates for Chromecast with Google TV 4K

Android 12 is also providing giving the Chromecast with Google TV new privacy switches for connected cameras and microphones, and upgrading its security patching to July 2022's levels.

HDR and surround sound settings have also been added, so you can pick your favorite options.
