问题
In the Options for the Google Cast extension under 'Tab projection quality', there are three options:
Extreme (720p high bitrate) High (720p) Standard (480p)
1080p is not listed.
I assume if I play a 1080p video that it will work because it's sending the video url to Chromecast, but am I limited to 720p for regular HTML webpages?

This appears to be more of a user question, not a development question.
The Google Cast extension for Chrome provides two major functions:
- Chrome Mirroring - which is limited to 720p - This acts by encoding your tab to WebM/Opus and then sending to the Chromecast device.
- The Google Cast API for Chrome which allows your webpage to cast a video to a Chromecast device. Which, of course can be full 1080p. Official documentation.
