extended desktop-monitor narrowing

[OBen1]

hi

The display used to fill my whole monitor screen but suddenly it narrowed, leaving a black band around the screen. the mouse pointer still gets to the whole area and when i watch a film it does fill the whole screen however, when i use the remote connection to another computer, it narrows the displayed remote computer screen. it it used to be full. How do I restore it to full screen?

thanks
