HDMI/DisplayPort suppory

What is the state of HDMI/DP support?

Can I simply plug a USBC to DP cord into any TV/monitor and get a screen mirror or similar?

I'd love to use this to replace casting, so would I be able to plug in and put Jellyfin onto a TV?

I'm currently on a Pixel 6, so no hardware support for it, but I plan on upgrading eventually.
