Using Xorg.conf how to setup non duplicate Monitors?

Hi, I'm having issues setting up 4 monitors. They are all the same brand/model monitors. For some reason, I can only manage to show chrome in the top left monitor and when you maximize it. It will snap on that monitor only. Or I can see a duplicate in all four monitors. For example, if I open a window, it will show 4 times, once in each monitor. I would like to span a window full screen in all four monitors using Xorg.conf.

Here's my current xorg.conf

Code:Section "Monitor"
Identifier "DisplayPort-0"
Option "Position" "0 0"
EndSection

Section "Monitor"
Identifier "DisplayPort-1"
Option "RightOf" "DisplayPort-0"
EndSection

Section "Monitor"
Identifier "DisplayPort-2"
Option "Below" "DisplayPort-0"
EndSection

Section "Monitor"
Identifier "DisplayPort-3"
Option "Below" "DisplayPort-1"
EndSection

# END OF MONITOR SECTION

# MAP Monitors to the outputs
Section "Device"
Identifier "Device0"
Driver "amdgpu"
Option "Monitor-DisplayPort-0" "DisplayPort-0"
Screen 0
EndSection

Section "Device"
Identifier "Device1"
Driver "amdgpu"
Option "Monitor-DisplayPort-1" "DisplayPort-1"
Screen 1
EndSection

Section "Device"
Identifier "Device2"
Driver "amdgpu"
Option "Monitor-DisplayPort-2" "DisplayPort-2"
Screen 2
EndSection

Section "Device"
Identifier "Device3"
Driver "amdgpu"
Option "Monitor-DisplayPort-3" "DisplayPort-3"
Screen 3
EndSection

# END of Monitor outputs
