Screen boundaires issue on multimonitor system

Hi ,
i have 2 extra monitors attached to my laptop connected though a usb3 docking station.
when i set an application full screen on “middle position” monitor , i can see a part of that application on the left monitor which is the laptop screen.
i changed resolution but the issue is still there.
i don’t know where to look

Thanks!
ps : i’m using amy-lignt-global-6 Theme
pps : sorry if i’m in the wrong topic, i can move if required

I’ll move it to the Hardware category.

The middle and RH monitor both seem to be offset incorrectly…

I would have expected (non-overlapping) horizontal offsets of 1920 and 3840 respectively. In any case, can you correct this by dragging the displays slightly in the Plasma display configuration utility?

You can also see the offset directly in the disply configuration utility when you left click the monitor icon and hold the mouse button. This helps to align the displays properly.

Hi ,
Thanks for the suggestions ,

After fiddling with display configuration screens positions , and try to move the screens to see the coordinates , i decided to cancel my modifications and then on next reload of the display configuration screen , i saw the offending screen overlapping the other.
I don’t know why it didn’t appeared before but i cannot reproduce the issue.

The issue is now gone
Thank you
