I recent got a new chromecast 4K. I’ve installed the plex app and tried playing a movie I have that is 1080p, 12.2Mbs, and it is was horribly pixelated, like it was too low bitrate. It was set to direct play.

I tried the same movie on my Sony android tv and it was crystal clear.

It’s not buffering at all and is direct playing, so it’s not a bandwidth issue. Any idea what the issue could be or how I can debug this?

The movie was sin city and has a lot of black and white so the pixelation is very noticeable
