Dual screen configuration (X11 + qtile)

Hello,
I want to use an HDMI monitor as my secondary monitor, but I can only configure it as a duplicate of my laptop's monitor
Here my 10-monitor.conf:
Code:Section "Monitor"
Identifier "eDP1"
Option "DPMS"
EndSection

Section "Monitor"
Identifier "HDMI1"
Option "DPMS"
EndSection

Section "Screen"
Identifier "Laptop"
Monitor "eDP1"
EndSection

Section "Screen"
Identifier "HDMI"
Monitor "HDMI1"
EndSectionAnd my qtile screens conf:
Code:Screens = [
Screen(
top=bar.Bar(
...some widgets...
),
Screen()
]
