Windows 10: DisplayPort connection not detected on Windows, working only on Ubuntu 18.04...

I recently bought second monitor and I've been struggling to make it work with my motherboard, but to no avail... :

Long story short - second monitor connected via Display DisplayPort is not detected at all in Windows 10. I've tried many combinations to make it work cables, adapters etc., but Windows is not detecting any connection. Of course new monitor works fine on HDMI. I've tried reinstalling drivers even with DDU and reinstalled Windows, nothing seems to work...

When I boot while connecing only one monitor via DIsplayPort, it's all black. Of course new monitor works fine on HDMI.

What is really strange, new monitor is detected while I boot to Ubuntu 18.04, but only in resolution 640x480 px. I need to manually force different resolution via command $ xrandr --addmode DisplayPort-0 1920x1080 ant then voila - it works! :

Can someone help me with this one? Windows is my daily OS...

This link has more details (steps to do it are for version 16.04 - 18.04 is slightly easier)

Here is how to do it for 18.04. Works on SCU

Errors in Ubuntu 18.04 on Windows 10

Hello,

I tried to migrate from WSL Ubuntu 16.04 to Ubuntu 18.04 but it did'nt work.

Then I tried to uninstall Ubuntu 16.04 but I got error 0x80070002

I finally succedeed in installing Ubuntu 18.04 but

I couldn't choose the same username as before, the majuscule in first position caused an error

adduser: Please enter a username matching the regular expression configured

via the NAME_REGEX[_SYSTEM} configuration variable. Use the `--force-badname'

option to relax this check or reconfigure NAME_REGEX.

Now, I have errors in Ubuntu 18.04.
