Ive got a 4k Chromecast connected via an HDMI Matrix (kind of like a splitter) to 2 TVs. I use the Chromecast to mirror a Chromebook to the TVs.
Im having a couple of issues with the Chromecast though (see below) in principal i think id be able to fix both of these issue pretty easily but i cant find out how to access the Menu / Tools of the Chromecast. It seems you used to be able to do this via a Chrome browser plugin (info here), but this has since been dis continued. Any ideas how to access the Tools / Menu now ?
Issues : - Time on Chromecast screensaver is wrong - Chromecast crops the mirrored image on the screen, on Apple TV this can be fixed by changing the overscan settings
