In the sense that we have dongles/docks, sure. In the sense of monitors with native USB-c input? These are still fairly rare as the accepted pattern is that your dock has an HDMI/DP port and you connect via that (which actually is a very good pattern for laptops).

As for TVs? I am not seeing ANYTHING with usb c in for display. In large part because the vast majority of devices are going to rely on HDMI. As I said above.

I'll also add that many (most?) of those docks don't solve this problem. The good ones are configured such that they can pass the handshake information through. I... genuinely don't know if you can do HDCP over USBC->HDMI as I have never had reason to test it. Regardless, it would require both devices at the end of that chain to be able to resolve the handshakes to enable the right HDMI protocol which gets us back to the exact same problem we started with.

And the less good docks can't even pass those along. Hence why there is a semi-ongoing search for a good Switch dock among users and so forth.
