Unable to use extended monitor with Intel uhd graphics 620

[SDess1]

I have a monitor (Acer G276HL) and when plugged in with a HDMI into my laptop, it only works if :

in 50 hz AND duplicated screen.

I want to extend monitors obviously but I'm not able to do it, even with the latest drivers updates.

Edit : got you the .txt

thanks
