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.
