Jitu

I am using twinview settings of my Nvidia graphics adapter to control the VGA port of my laptop for a second monitor. A few days ago I saw that a horizontal black bar which was not accessible by the mouse appeared on the second monitor. The lower part of maximized windows was also missing as if the whole screen moved up and the visible area stayed at the same place. I did not know, what I did or changed nor I did not recognize it immediately.

Since the space was around 25 pixels I assumed that the Gnome panel is interfering somehow first. The vertical alignment settings did not go so far to compensate that much width of the black bar. Since I assumed a software problem I started to dig around for a solution and tried to recall, what I actually did. By accident I found the solution: The monitor has a “Reset to factory defaults” setting. After everything was reset, the black bar vanished. So I must somehow changed a setting such as “Auto Adjustment” or so, which messed up the visible area. I heard that some users had a vertical black bar which also vanished after reseting the values.
