Display/screen size, appears 'zoomed'

[JonnoGenie]

My girflfriend is having a problem with the display on her Dell Inspiron 8600 laptop (running XP).

All of a sudden, everything, the desktop, wallpaper, open webpages etc., seem significantly larger than they previously were. It is like having had a page set as 'view at 100%'size, and now it is at view at 150%.

The result is the icons, font etc are significantly larger, there is less visible at a time, and you have to scroll around a lot more to do tasks. She tried reverting to a pre-problem restore point, but this changed nothing. There was no apparent reason for this change originally happening.

I've tried to look into this ( via 'Help and Support'), but don't even know how the problem might be correctly described, so that has yielded nothing to date.

Can anyone help me by explaining how this problem might be correctly described?

Many thanks!

It would appear that you have reset the screen resolution.
If you right click on an empty section of the desktop and click properties then settings you will see the current resolution. you should then be able to change the resolution to the one you prefer
