Besides streaming online 4K content from Chromecast Ultra to TV, you may also come the idea to cast local 4K video to 4K TV with Chromecast Ultra, the fact is that most 4K video are encoded with H.265/HEVC codec, can Chromecast Ultra support H.265 playback?
Chromecast Ultra only supports to play 1080p H.265 video
Although Chromecast Ultra has claimed expanded codec support for HEVC HEVC Main and Main10, VP9 profile 0 and 2, however, online tests from users reflects that Plex transcodes HEVC when using CC Ultra playing 4K HEVC video files. 1080p HEVC 8-bit and 1080p HEVC 10-bit videos can be played on Chromecast Ultra without any transcoding going on. It also means that Chromecast Ultra can play 1080p HEVC video but fail to handle 4K HEVC video. Perhaps you can use Plex to transcode HEVC for Chromecast Ultra streaming, but the process will be very CPU intensive.
