Google is adding a new feature called “Video Smoothness” to Chromecast Ultra. This feature, turned on by default, will ensure that Chromecast prioritizes frame rate over resolution, for a smoother playback.
Allow me to explain.
4K resolution, without a screen that can support an adequate refresh rate, will result in choppy video playback. As a workaround, Chromecast will now play content in 1080p, reducing the resolution to improve the refresh rate. This will ensure smoother videos on your TV.
Chromecast Ultra is designed to pick the maximum refresh rate (up to 60Hz) and resolution supported by your 4K Ultra HD TV’s HDMI connection Some TVs are incapable of a 60Hz HDMI connection at 4K resolution. When connected to such a TV, the video smoothness feature will select a 1080p 60Hz connection to ensure fluid playback and prevent jerkiness or stuttering issues when viewing content. Video smoothness is on by default.
This feature is turned on by default. If you wish to disable it, (which is not advisable) “Chromecast Ultra will prioritize playing the content at the highest resolution while lowering the frame rate to fit the constraints of the TV. So a 4K TV that doesn’t support 4K 60Hz will default to 4K 30Hz.”.
Here is how to disable Video Smoothness:
- Make sure your phone or tablet is connected to the same Wi-Fi as Chromecast Ultra.
- Open the Google Home app .
- In the upper right corner of the Home screen, tap Devices .
- Scroll to find the device card for the Chromecast Ultra you’d like to adjust.
- In the top right corner of the device card, tap the device card menu > Settings.
- Under “Video smoothness”, slide the slider off.
