U2422HE, No USB-C signal from your device, #4
I just purchased a Dell U2422HE monitor, worked on first use, but now I'm getting the error "No USB-C signal from your device". Can you please help? Other USB peripherals seem to be working (laptop is charging through USB-C and wireless keyboard/mouse running through USB dongle just fine.

To receive assistance from Dell support, they need to verify the warranty status and ownership. Click the "Get help now" icon on the right to start a live chat session. Provide to them the private U2422HE Service Tag.
Be sure that the provided U2422HE USB -C to USB-C cable is connected to the U2422HE #6 (Video + data) USB-C upstream port.
Not to the #8 (data only) USB-C upstream port or the #13 USB-C downstream port.
If still no go, perform the no cables reset =
* Turn the U2422HE off
* Disconnect every cable (including power cable) and peripheral device from the U2422HE
* Press and hold in the power button for 8 seconds
* Reconnect cabling and retest
