The Chromecast with Google TV is already one of the best streaming devices, but it just got even better. A new update adds a very important feature: Dolby Vision. Some other upgrades.

Dolby Vision is only available in a few apps, but it's huge for those who have TVs that can support this kind of HDR. Also, security and storage updates would be quite helpful.

Adding Dolby Vision support to the Chromecast with Google TV is a big deal. Not only does this mean that the Chromecast will offer Dolby's premium HDR technology, but it will also support all HDR standards. After all, the dongle received HDR10+ certification earlier this year and has supported both HDR10 and HLG for some time.

As you will see in our guide to all HDR standards, Dolby Vision is the leading licensed HDR format. The main appeal of Dolby Vision is that it provides an end-to-end solution for film production, allowing directors and video editors to set HDR conditions that fit their intentions rather than adding metadata to existing material.

Unlike HDR10, Dolby Vision uses dynamic metadata to provide scene-by-scene and frame-by-frame adjustments to bring out the best visuals in every shot. It also boasts the broadest standard, allowing for higher resolution, higher peak brightness, deeper black levels, and a 12-bit color gamut beyond the commonly used Rec. 2020 color space.

This update to Chromecast with Google TV also means that Google can better compete with other streaming devices, including Roku Streaming Stick 4K and Apple TV 4K. And at a more affordable price.

According to Android Community, the new update will consume an extra 158MB of existing storage space on the Chromecast. However, the new patch actually optimizes storage, and users have reported 200-300MB extra space after the update.

It also includes better DRM video encoding, a dedicated uninstall app menu, and the latest security updates. Sadly, the device is still running the version of Android 10 first released in 2019, which is the October 2021 version. Still, better security is always a bonus.

Chromecast can be updated by going to the Settings menu > System > About > System Update. Make sure you have enough space. Otherwise, you will miss these upgrades.
