The Beta version of the Google Cast extension for Chrome has been updated with 1080p support. If you have a powerful computer and a good network connection, tab casting will look a lot better with this change.
From the official announcement:
The latest version of the beta extension (version 14.826.0.4) has an additional section on the options page that offers a higher level of control over tab casting. These settings are really for those who want to experiment with what works best – if they seem confusing, you are perfectly safe in ignoring them! The available settings are as follows:
Now, the resolution control:
Resolution – This controls the resolution of the video stream sent to Chromecast. Until now, the built-in settings (Standard, High, and Extreme) only enabled 854 x 480 and 1280 x 720 to be supported. If you’ve got a powerful computer, you can now push this up to 1920 x 1080. This can also work well if you use tab casting primarily when browsing the web, or for viewing photos, where detail is more important than smoothness. Note that while it’s always tempting to run at the highest settings, if your computer’s display is lower than 1920 x 1080, you’ll get little benefit from choosing this setting.
If you have never heard of the Google Cast extension: The Google Cast extension enables you to find and play content on your Chromecast device from your Chrome browser.
A note to those who are using the stable version of this extension, if you want to switch to the beta version, you must uninstall the stable version before installing the beta.
