I am helping a colleague with his Dell Inspiron 8100 laptop. The current resolutions is 1400 x 1050 which fills the 15" screen but the icons and text are miniscule. On literally all other PC's that I have worked on one can use the display properties to lower the resolution to "enlarge" the desktop appearance albeit have a smaller footprint. When I try this on this particular machine the viewable image actually shrinks leaving large black borders around the display area. The lower the resolution the larger the black borders. I've updated the drivers retrieved from the Dell site but I am at a loss. This is a NVidia GForce machine. Does anyone have any recommendations or hopefully had experience with this issue before and provide a suggested resolution? Thanks in advance.
