USB-C second monitor is not working

Hi everyone! First of all, I'm a begginer in the arch/linux world and I really need a support with this issue.
I have a laptop with one HDMI output and a USB-C port. I want to connect a second monitor with the USB-C/DisplayPort (I already have a monitor connected in the HDMI port thats works!). I want to use a USB-C to HDMI adapter. The computer simply doesn’t recognize the monitor. The screen stay black all time when its connected with the adapter. It’s valid to say that in Windows10 this connection works.
I’m using the video-hybrid-intel-nvidia-455xx-prime as a graphics driver.

Here is some information:

xrandr --listproviders :  (with Optimus-Manager set to INTEL)
Providers: number : 1
Provider 0: id: 0x48 cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 4 outputs: 5 associated providers: 0 name:Intel

I've already tried to install the DisplayLink driver, but following the wiki steps I'm stucked at the

xrandr --setprovideroutputsource 1 0

because my Xrandr only shows me one Output(intel)!!

As you can see, I'm using the Optimus Manager. I tried with the 3 options provided by him: INTEL / NVIDIA / HYBRID
I really don't know what can I do anymore! I'm accepting any suggestions. Sorry for my newbie question! Thanks
