This can be the product of several different settings.



If the problem is only in your web browser, you can typically set the default text size in one of its pull-down menus. For example, in Internet Explorer, choose View-%26gt;Text Size and then pick which size you want.



If everything on your screen has changed size (including, for example, the text under icons under your desktop), then this could be a product of either the Screen Resolution, or it could be affected by the DPI setting. Both of these can be found on the Display control panel (go to Start-%26gt;Control Panel, then double-click on Display).



Since you're on a laptop with a LCD screen, there is really only one ';native'; Screen Resolution that you'll want to use. Any other setting for this parameter will not look sharp. For DPI, you typically want this set to 96dpi.How to change all my letters on laptop screen from small to large size?
If you have XP, click on the ';View'; tab, then select text size, you can pick from smallest to largest. I have mine set to medium. I have also learned by accident that if you push in control and hole it, then use your wheel on your mouse, you can change text size too.
