Windows 10: Enabling USB Type C (Thunderbolt) socket

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.

Enabling USB Type C (Thunderbolt) socket

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.

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.

Did you read this in the monitor manual?

NOTE: Except for USB Type-C input, the monitor automatically determines which inputs have valid
video signals. You must manually select USB Type-C input. To select any input, including USB Type-C,
open the OSD menu and select Input.

Did you download the Thunderbolt driver from Gigabyte website? I see you say you installed a driver, but was it the one from Gigabyte website?

Hi NavyLCDR,

Thanks for responding so quickly.

Yes, yes and yes!

Yes, I'm aware that the monitor doesn't auto detect the Type C connection and so selected that from the monitor controls. While it shows a Type C cable is connected, it doesn't find a signal when selected.

Yes, I downloaded the latest Thunderbolt driver from the Gigabyte website for my motherboard.

Yes, I've gone into BIOS, but there is no such thunderbolt menu. There is a USB menu, but it doesn't say anything about thunderbolt! I have upgraded my motherboard to the latest available BIOS, which is F8 according to the Gigabyte BIOS tool.

It does feel like I need to do something to switch on the Type C port on the motherboard!

I managed to use the supplied HP Type C to Type C cable to connect the monitor to the desktop. It wasn't easy due to its short length but I got the same results as with the new 3m cable, so it would appear it isn't a cable issue as two different cables have now failed to work.
