To recap

Chromecast Ultra is an easy and predictable upgrade and a device that makes complete sense supporting the latest formats for video streaming to your TV. However, unlike the previous two Chromecasts that plugged a gap in your TV’s skills, the Chromecast Ultra is likely to step on the toes of features that your TV already offers.
