I'm ignorant on this topic, can you not just plug a USB dock with HDMI out in any android phone and get a display out? I do it all the time on the previous three pixel phones I've had, but I didn't know that this was limited to those?
USB-C is only a connector/socket - a device having a USB-C socket does not guarantee much beyond being able to plug a USB-C connector into it.
Some USB-C devices only use the port for charging for example. Others might only support USB 2.0.
Getting a display out from something with USB-C socket needs the device to support something called DP Alt Mode.
Note that cables matter too - you can have a DP alt mode enabled monitor and phone, but if you have the wrong cable it won’t work. Welcome to the future.
