The iPad resolution trouble when connecting the sidecar.
I'm using iPad Air 4 and IMac 27".
Until yesterday, the iPad resolution came out well when connecting the sidecar.
However, when I connected the iPad today, there was a problem with the resolution.
(Check the picture file.)
I tried everything, such as rebooting my computer, disconnecting, and deleting "com.apple.windowserver.XXXXX.plist".
But it still doesn't work.
How should I fix it?
