Troubleshoot display settings
My non-HDR video looks too saturated
Your Chromecast's HDR settings are automatically turned on, so the colors in your video might appear too saturated if you play SDR content. To fix the color, you need to turn on Match content.
HDR video output isn’t working at all
Some TVs may require the HDMI signal format to be set to "enhanced mode" to support HDR video output. Check your TV display settings to see if "enhanced mode" is turned on (this may be labeled differently depending on the TV model).
