ASUS FA506IV AMD integrated graphics with Nvidia hybrid

Hi everyone, I have an issue with my recently purchased laptop that is using the hybrid combo AMD iGPU and Nvidia dGPU. I have installed the proprietary drivers and the HDMI port is working with AMD graphic card and I tried to connect another monitor through the Displayport USB Type C which is supposedly to work with the Nvidia dGPU (this laptop only works with iGPU on the HDMI and dGPU on the Displayport Type C) but I only get a black screen. The system recognize the monitor but there is no image, Any idea about this? sorry I’m kind of noob with this type of setup.

this is the output of the glxinfo -B
