Hi @ldvy , as you mentioned you selected a resolution lower than yours , so change it to 1360x768
and please provide garuda-inxi every time you have an issue .


Exactly i set a lower resolution because is the only way to avoid the black bar appearing, when i select 1360x768, the black bar just appear, as I showed in the print

please go the terminal and paste this : garuda-inxi
copy what you got and past it in a comment

Failed units:

please do reboot to your system , and it appears that you have 2 monitors “1366x768” and “1360x768”

so you have to adjust every monitor resolution independently,for the Samsung use → “1360x768”
and for your HP → “1366x768”

already tried this, black bar still appearing =(

Hi @ldvy , i would recommend trying other DE (Gnome , XFCE ,etc…)since there is no clear answer to this .
