Dual 1080p Monitors XFCE display problem

Hello, i use manjaro XFCE and i have a problem with my dual monitor setup, i have a Samsung CFG73 as a main display( connected through a DisplayPort ) that's on the left side and an AOC (don't know the model of, connected through HDMI )that's on the right side, both are 1920x1080. The problem is that i can't use both in "extended" mode, they both work only in "mirrored" mode, i tried deleting ~/.config/xfce4/xfconf/xfce-perchannel-xml/displays.xml it worked once, after reboot stopped working, i can get an image only on the AOC one when set up as "extended".

Try xrandr command to set both outputs properly.
If it fails, post error messages or system behaviour.

Hi, thanks, I already tried xrandr, it doesn't give any error messages and about behavior it's the same thing, I used xrandr --output DisplayPort-0 --auto --output HDMI-A-1 --auto --right-of DisplayPort-0 and in the meantime I tried switched DE's, I thought that it was a xfce bug, I switched to I3 now and it's the same thing
