Dell XPS 9350 - No Signal to External Monitor

I bought an USB-C to HDMI adapter cable to connect my Dell XPS 9350 to an external monitor (Dell U2414H).

I connect my laptop with adapter via USB-C, the HDMI port of adapter with HDMI cable and the HDMI cable with the external monitor. After that, the external monitor detected the laptop but it displays error message like that "There are no signal from your computer. Please press any key to wake up it".

My laptop still running, I also changed mode to duplicate or external screen and update all drivers but nothing change.

I checked the Intel Graphic Setting, it also detected the external monitor.

Please see attached images for more information and help me to fix it.
