it won't really detect it without major doing, but I see windows has a trick for doing it forcing to extend to a nonexistant display then mirroring all the content to the chromecast in which the content going to the tv is first, and content going to the computer is able to be managed- https://www.youtube.com/watch?v=miGe5u-LFYQ
maybe setting the virtural desktop to extend to the left so over flow starts on the tv - would be a dirty hack - but would make it very nice to throw anything you want up to a tv. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1450436 Title: Configure Chromecast as monitor Status in unity-control-center package in Ubuntu: Triaged Bug description: THIS IS A KIND FEATURE REQUEST -- not a bug Under System "Settings > Displays" it would be really nice, if Chromecast devices were automatically detected and appeared like any normal monitor that is connected directly to the computer; ie. unity- control-center should transparently allow the Chromecast device to be used as a secondary or even a primary monitor, configure mirroring, launcher placement, scale and everything. Resolution of a chromecast is most likely fixed and the option should therefore be ghosted. But when configuring a screencast-to-Chromecast from the Chrome browser, an image-quality-vs-refresh-speed option is present, so a dropdown for this is necessary here too. Remember to state the Chromecast device name so one can tell multiple chromecasts from another. I've added a screenshot to demonstrate the idea. I'm currently running Ubuntu 14.04, so I don't know if this has actually been implemented in 15.04. But I haven't found any blogs describing it.
