Thanks Lea, Your solution work perfectly. No more black borders and using the entire area of the client. Also, the issue with „the mouse cursor needs to move to the right of server screen and enters from the left of the client screen.“ was due to user error; In Windows 11 when I changed the client screen position, I did not notice I needed to click Applied button that pops up to save the setting. All is good, have a happy new year.
