Getting actual width of Chromecast receiver UI
问题 I have a second generation Chromecast connected to a monitor. I'm receiving 1080p60 from the Chromecast. The Cast documentation states in several places that the UI is at the resolution of 720p: While Chromecast displays the receiver page on a 720p graphics plane, other Cast platforms including Android TV may display the page up to 1080p. And, this note on media formats: Images have a display size limitation of 720p (1280x720). Images should be optimized to 1280x720 or less to avoid scaling
