You mention using a USB-C dock to take the video and USB from the PC and connect the USB-C port to the monitor. Those docks don't work like that. They won't combine DP and USB into USB-C, they take USB-C and split that out into DP and USB. Maybe there is such a device but I haven't seen one yet. To switch video and USB together will take a KVMConnect the power cord (shown below) to the back of the monitor and the other to an outlet or power strip (ideally with surge protection ). Note. Some flat pannel displays use an AC adapter instead of a power cable. For these displays, a cable may go from the monitor to the AC adapter, which plugs into the wall. Turn on the computer and monitor. Yes, it is possible to connect computer monitors with USB cables or USB C cables to transmit data. Here’s How To Connect Monitors Using USB Before you start, you'll want to go ahead and purchase a USB to HDMI adapter.
DisplayPort 1.4 can deliver 4K 60Hz video using only two lanes, with a new high-bit-rate mode called HBR3 with a compression mode called DSC. This makes it possible to get 4K60 video and USB 3.1 ports in the same hub, but only if the computer, hub, and monitor all support DisplayPort 1.4 and HBR3.
If you're using an older device that only has USB-A plugs, but your computer just has a USB-C connection, you can still utilize that USB 3.1 port with that device using an adapter that has the appropriate connections on both ends (USB Type-A on one end for the device and USB Type C on the other for connecting it to the computer).
In some cases, USB-C can also transmit DisplayPort audio and video signals for connecting your device to an external monitor or TV. (The port in question needs to support a standard called OsSO8B.
