Help- 2 y.o changed screen setting

[bub1]

HI
In a matter of about 2min, my daughter managed to get to my computer and changed my screen settings.
The screen is enlarged and when I touch the mouse the whole screen moves as well.
I have tried changing the screen pixels in Systems preference but don't know which one it should be- although I have tried all of them and nothing changes!
I have an Imac version 10, 20inch if that helps.

If anyone can solve this it would be really appreciated as it is driving me nuts that I cannot change what a 2 year old has done!!

TIA

Open System Preferences and click on Universal Access in the System section.

Select the Zoom Tab and see if there is a check in the "Zoom" box.

If so, then turn this feature off by clicking inside the Off box.

These features can be turned on/off using the keyboard combo of Option ⌘ 8. I think it is designed for the visually impaired. When in a web browser I use the ⌘ +/- to increase/decrease text size.
