Windows 10 Vostro 5481 can not connect to external display via usb type-c

[Ild mal]

I have 5481 and monitor samsung c34h890.

Laptop has usb type-c with power delivery and display port(same as 5471).

- Windows 10, latest updates.

- Updated all firmware (bios, chipset, etc)

- Disabled power options in usb settings

- Reinstalled usb drivers 100 times

- Reinstalled windows

So when i connect display i get it constantly reconnecting. It says usb plugged in, plugged out.

Sometimes i get big "number 1" on my laptop, which means it connects display, but then it dissapears.

Also if i go to screen settings, i see blinking resolution settings, but cant change them.

In devices i get this sequence:

Geneic Superspeed Usb Hub:
