It is a comon sence, monitor can adjust Vertical and Horizontal position
and scale, via OSD of monitor panel, it is easy to adjust by yourself.
because it is display normally when you set precision in 10768, So I
judge the reason is " VERTICAL SCALE SETTING TOO LARGE" or "VERTICAL POSiTION A LITTLE UPWARD", no doubt !
Why you don't consult with the monitor dealer ?
