The $DISPLAY is expanded by user shell
_before_ sudo is executed. I would suggest comparing output of
printenv | 'DISPLAY|XAUTHORITY|HOME'
sudo printenv | 'DISPLAY|XAUTHORITY|HOME'
Here the output is identical and displayconfig
starts up fine.

go wrong (see man xauth. Section FILES and ENVIRONMENT and -f)

To me vi is Zen. To use vi is to practice zen. Every command is
a koan. Profound to the user, unintelligible to the uninitiated.
You discover truth everytime you use it.
