CC268 :
I'm afraid neither of those fix the problem...
Okay, well I thought I would start with the simplest solutions, just to get those out of the way.
If we can't figure something out, you can always just rollback the update.
One thing worth trying... Go back to "Screen Resolution"
From there, go to "Display"
Tick the box: "Let me choose one scaling level for all my displays"
then click on 100%
(Sign out, sign back in)
Did it work?
If that doesn't work, could you just let me know what is your resolution is supposed to be and what is it now?
Good luck!
