Chromecast: what changes with the new update?

Google is rolling out a new April update for the Chromecast with Google TV launched last year. It’s a pretty big upgrade for a streaming device – a total of 166MB on my Chromecast – but it includes a number of improvements.

After installing the new software and restarting the Chromecast, you’ll be able to dig a little deeper into the video settings than was previously possible. In the new settings area “advanced video controls“, You now have the option to choose your preferred dynamic range format. Options include Dolby Vision, HDR or even SDR if you times keep it there. You can also manually switch to a ton of resolutions at various refresh rates from this menu:

4K (60Hz / 50Hz / 30Hz / 25Hz / 24Hz / smpte);

1080p (60Hz / 50Hz / 24Hz);

720p (60Hz / 50Hz);


1080i (60Hz / 50Hz);

576p (50 Hz);

480p (60Hz).


Unless you have a good reason to make a change, we recommend that you keep the Chromecast and its selections as the default: in our case it’s 4K 60Hz.

Google says this update also improves Chromecast with Google TV’s Wi-Fi performance on 5GHz networks and mesh systems. For the full list of enhancements, see below. I’m still waiting for a way to delete the line “keep watching“, Where programs and movies can sometimes get stuck, even after you’ve finished streaming them. Here is the official changelog:
