There are several possibilities. Was the screen resolution set to a higher value, and all of sudden has reset to a lower value? If so, the drivers for your video card may need to be reinstalled. Is this an older computer? If so, the video card may not be capable of resolution as high as the monitor is capable of displaying. Are you working through the Windows Control Panel, or are you trying to change the resolution by using Device Manager? Resolution should be changed in the 'Display' section of Control Panel.
