🔥 Arduino Portenta H7 DisplayOut over UsbC ?!

Hi Im a beginner and am working on this example: https://docs.arduino.cc/tutorials/portenta-h7/creating-gui-with-lvgl

Im not able to get past step 4.

Unfortunately Im not able to get any image from the Portenta to a TV or monitor.

My cable setup is exactly the same using a usbc hub. Ive also tried using only a usbC to Hdmi cable, without luck ( I guess power supply missing?!)

I hope somebody here is able to help me out.

Its really frustrating not being able to run the examples.

If somebody could give me a hint or give me directions, Id really appreciate it.

I would also pay for it over paypal, if someone could help me get this running.

Best Regards
Chris
