I've tried many fixes for adding this mode, but none have worked. Using xrandr --fb 1920x1080 gives me the error: BadValue (integer parameter out of range for operation). I installed my nVidia drives according to the Arch Wiki (pacman -S nvidia). I'm not sure what else to try. Any help would be great, thanks!
EDIT: After trying yet again to modify xorg.conf, upon reboot I now have full resolution options. Not sure why it worked this time but the issue appears to be resolved.
