I have a Philips monitor capable of displaying 1680x1050, which I am currently using and it works fine. But sometimes I'd like to connect this monitor to an older laptop whose native resolution is 1024x768. But when I connect the laptop's external video output to the monitor, I can see only about 80% of the display (ie, the boundaries are not correct). I tried to adjust the monitor's settings (via the monitor's own buttons) but it doesn't work. Nor the "auto adjust" button on the monitor.
