Dual monitor stopped working after windows 10 update

So yesterday windows 10 decided to do a big update, the one where it reinstalls the os.

Everything seemed fine, but then I realized that my 2 monitor setup stopped working. It was set as "duplicate" where monitor 2 was the main display and 1 was the secondary.

In DISPLAY SETTINGS I tried to set it back to duplicate or extend or show only on 1 (it shows only on 2) bit with no success:

It looks loke windows is doing that and it pops up the regular "do you want to keep settings or revert" thingy, but it actually just leaves monitor 2 as the only display.

Also, the "make this my main diaplay" is grayed out.

I tried installing new latest nvidia deiver using DDU, rolling back to older driver, nothing changed. Only thing helping is plugging out the cable of one of the diaplays. Then i can get the one that i want to work and exchange if I want by plugging out
the other cable. What now???
