Chromecast Ultra is similar in design to the second-generation model, but features upgraded hardware that allows the streaming of 4K resolution content, as well as high-dynamic range (HDR) through the HDR10 and Dolby Vision formats. (The maximum resolution of the "Ambient" screensaver features is 1080p.)[33] Google stated that the Chromecast Ultra loads video 1.8 times faster than previous models.[34] Unlike previous models that could be powered through a USB port, the Chromecast Ultra requires the use of the included power supply for connecting to a wall outlet. The power supply also offers an Ethernet port for a wired connection to accommodate the fast network speeds needed to stream 4K content.[35] The Chromecast Ultra was one of the first devices to work with Google's cloud gaming service Stadia; a Chromecast Ultra was included with a controller in the "Founder's Edition" and "Premiere Edition" bundles for Stadia.[36][37]
