Started out of the blue. The screen grew very large and then

shrunk very small. Then it went to each extreme rapidly several times until
it stayed extreme large. The cursor is 2 inches long. It boots up normally and when it finishes booting it jumps to the large size. I have this page bookmarked but I can't find it in the forums. It shows up in a sidebar in my browser when I go to the bookmark.

Take a look at System Preferences,

Universal Access and make sure you do not have anything turned on in there that should not be, especially under the "Seeing" Tab.

If that all looks alright, you may want to consider deleting the Finder Preferences from the Library Folder.
There are two of these, one in your Home folder and the other at the root of the Hard drive.

Problem solved. Thanks to anyone who was about to help.

I kept searching Google and found the answer buried deep in a reply to someone's similar problem.
Hold down the control key and scroll the mouse down to reduce the screen size to fit the monitor.
So simple when you know how. Thanks again.

Not sure that is the problem you were describing.

"The screen grew very large and then shrunk very small"

Zooming on the scroll wheel will not make the screen go any smaller than the screen size, it will only make the screen image go larger.

Either way, I'm sure you are happy to have found a solution.

You are right, I may have 2 problems. The immediate one

of the large screen is solved. The one of the screen zooming up and zooming down on it's own may be another.
I neglected to say that I use a Wacom Intuos pad. In the upper left corner of the pad is a slider that zooms the screen up and down. Somehow I inadvertently end up on this slider and that may trigger the screen to go haywire. Since it is only once in a while I think I can deal with it.

(NT) OK, seems like you have a handle on this.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
