Triple Monitor Setup is NOT working

I am a newbie and just started using arch. For what I have installed, I have xorg, i3-wm, and nvidia installed. I have 3 monitors, one is connected using HDMI, another DP and the last one is a DVI-D that has an adapter to HDMI (DVI-D into GPU, HDMI into monitor). I have a GTX 1650.

When I run xrandr:

Screen 0: minimum 8 x 8, current 3840 x 1080, maximum 32767 x 32767
DVI-D-0 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm

   640x480       75.00    72.81    59.94    59.93

   1920x1080     60.00 + 165.00   143.85   119.88   100.00    84.62    60.00    59.94    50.00
   1680x1050     59.95
   1440x900      59.89
   1280x1024     75.02    60.02
   1280x720      59.94    50.00
   1024x768      75.03    70.07    60.00
   800x600       75.00    72.19    60.32    56.25
   720x576       50.00
   720x480       59.94
   640x480       75.00    72.81    59.94    59.93
DP-1 disconnected (normal left inverted right x axis y axis)
None-1-1 connected (normal left inverted right x axis y axis)
   1024x768      60.00 +

And when I run: xrandr --listmonitors:

Monitors: 2
 0: +*DVI-D-0 1920/597x1080/336+0+0  DVI-D-0
 1: +HDMI-0 1920/597x1080/336+1920+0  HDMI-0

I've tried simple things like rebooting it and occasionally will my DP monitor display anything, but 90% of the time it doesn't.

Re: Triple Monitor Setup is NOT working

welcome to the boards

Please post outputs wrapped in [ code ] [ /code ] tags (without the illustrative spaces here)

Get rid of the simpledrm device/potentially add the kernel modules for nviia to initramfs so they are loaded early: https://wiki.archlinux.org/title/NVIDIA … de_setting -- but you definitely should set the nvidia_drm.modeset=1 kernel parameter.
