In the Chrome browser, if I'm on a streaming site, a right-click offers me the option of casting to my TV. The TV has a Google dongle attached and everything works fine, displaying the video both on my Ubuntu screen and on the TV screen.
On YouTube, there is an additional "Cast to TV" icon at the bottom of the screen. This sends the video to the TV, but without also playing it on the Ubuntu screen.
Playing on both screens is distracting and uses a lot of CPU.
Is there some way of getting this "Cast to TV" effect on other sites that don't offer the "Cast to TV" icon?
