I just had the motherboard on my Dell Dimension XPS replaced.  Now all of the icons on my 2405FPW Monitor are very tiny, everything on aol is tiny and when I play a DVD, the fullscreen DVDs are blacked out on both sides of the movie when it used to fill the entire screen.  I tried going into "Control Panel, Appearance and Themes, Display, Display Properties, and Settings" to make sure the screen resolution was set to 1920 x 1200. 

Can anyone help me configure it?

Thank you...
