I have a 2017 imac 27 with two external monitors connected via usb-c to display port. One monitor is run in landscape and the other in portrait at a 90 degree rotation.

This setup has worked perfectly for the last six months but recently every time it is powered up or woken from sleep the external monitors have swapped rotations. This leaves me with the landscape monitor at 90 degree and the portrait back to 0.

Now I have to use preferences or pull out the cables to revert the rotations back every time I use it.

Any suggestions on how to fix this problem?

Your help and time is appreciated.
