Question about i-tec USB Typ C — DisplayPort

Ciao. You will get a picture. But charging will not work because, as far as I know, DisplayPort has no lines for powering a device.
If your AOC monitor has an input in USB-C format in addition to the USB 3.2 port mentioned (which is probably in USB-A format), then you should simply use a corresponding USB-C to USB-C cable. For example, https://www.digitec.ch/de/s1/product/satechi-usb4-c-usb-c-080-m-usb-40-usb-kabel-20839089. But it probably doesn't have this and that's why you're asking this question. In that case, I recommend taking a look at the monitor manual to see what this USB port can be used for. It is probably intended more for smartphones and other smaller devices such as hard drives.
