I have a desktop using a GA-Z270X-Gaming 7 1151 7th gen ddr4 rgb fusion motherboard, which includes a USB Type C port also described as a Thunderbolt 3 port.
I've just purchased a new HP Z38C monitor, which includes some USB ports, however, to use them a cable must be plugged into the Type C inbound socket on the monitor. This monitor also provides video via DisplayPort, HDMI or USB Type C. Currently, I'm using a DisplayPort cable.
According to the monitor instructions, it suggests using a Type C to Type A cable to connect the monitor to the desktop in order to enable the 3 available Type A ports on the monitor.
Because the motherboard has a Type C port I thought it would be better to use this to connect the monitor, so I purchased a 3m Type C to Type C cable.
However, when this cable is connected, the USB ports on the monitor are still not working. A short Type C to Type A cable came with the monitor so I plugged that in and the USB ports on the monitor do work. With this cable, I'm not using the Type C port on the motherboard.
When the new Type C to Type C cable is plugged in the monitor control panel shows "USB-C Video Connected" and when the cable is disconnected, the monitor shows "Inactive", so clearly the monitor is detected a Type C cable is plugged in.
If I try to select USB-C Video as the video input on the monitor, it doesn't find a signal.
Am I wrong to expect the Type C to Type C cable to "just work"? Why aren't the monitor USB Type A ports working when using the Type C to Type C cable to connect the monitor to the desktop? Same with the video signal? It would appear that the Type C port on the motherboard isn't working!
I have installed the latest Gigabyte Thunderbolt driver, but this didn't make any difference.
I "suspect" I could purchase a Type C female to Type A male adapter and plug the new cable into a standard USB Type A connector on the motherboard, but I would much prefer to use the Type C port if possible.
Do I need to do something to turn "on" the Type C port and pass video through it or simply use it to allow the USB ports on the monitor to work?
Thanks.
