I just purchased a XPS 8940 with Windows 10 pro ?(the invoice says Windows 10 pro but sales rep said Windows 11 was to be installed prior to leaving warehouse- so not sure) and a U2719DC monitor. When I connect the USB Type-C cable provided with the monitor to the XPS on the only type c connection (which is on front of the XPS), I get a message saying "No USB type-C signal from your device". I have tried to connect the type-c cable to a usb cable to attach to the XPS, and still get the same message. Any suggestions on how to connect this monitor to the XPS
