HI...I have a problem...my display and everything on screen get bigger...i was tired with Display Properites>Setting>Screen resolution (1024by768 pixels) or color quality but it cant get smaller...and i had tired Accessibility option (Magnifier)...but it not help....can u help me please....

Is this a new problem? Were things working OK previously? Any new hardware or software?

If this is a new problem try a System Restore to a point prior to the problem:

start > All Programs > Accessories > System Tools > System Restore


Otherwise you may need to reload your Graphics Drivers.

ID you Graphics card via the Device Manager: start Run... devmgmt.msc > Display adapters

The web site for that manufacturer will have the latest drivers and installation instructions.
