My screen resolution changed, and I don't know why. How fix?

I have an HP pc and and HP w2007 monitor. When using Yahoo, everything is smaller and the characters look rough, and less sharp. How do I fix this? Was this some automatic Upgrade? I have windows vista. Thanks

press start
control panel
appearances and personalize
adjust screen resolution
use the slider to adjust to the you want press apply

or if you want to do a quick size change hold down control and use the mouse wheel this is ideal if you want to get bigger words or more onto the screen at once just temporarily
