If you didn't change the screen resolution buttons on the monitor itself, Try these steps and see whether they help.

To change your screen resolution

Open Display in Control Panel.

On the Settings tab, under Screen resolution, drag the slider, and then click Apply.

When prompted to apply the settings, click OK. Your screen will turn black for a moment.

Once your screen resolution changes, you have 15 seconds to confirm the change. Click yes to confirm the change; click No or do nothing to revert to your previous setting.

OR

To open Display

Click Start, click Control Panel, click Appearance and Themes, and then click Display.

A higher screen resolution reduces the size of items on your screen and increases the relative space on your desktop

When you say shrunk, do you mean the screen size or the text and icons on it?

If it's the screen size, you need to use the controls on the monitor to adjust that. If it's the content of the screen, you need to change your resolution.

If you mean that your monitor shrunk to a microscopic size while still working, you could be very rich if you can work out how you did it :D
