VertRefresh 56-76
[[Section “Monitor”
Identifier “Monitor0”
VendorName “Unknown”

VertRefresh 56-76
Option “DPMS”
EndSection]]

make a backup for this file
/etc/X11/mhwd.d/nvidia.conf,
90-mhwd.conf is an alias

Oh Thank you sir!
I think /etc/X11/xorg.conf is not working in manjaro
and it replaced with /etc/X11/mhwd.d/nvidia.conf
