2.) Using a ruler and the monitor's controls, make the three horizontal lines on the monitor calibration
screen the same length. Type this length in millimeters in the box in the center right of the screen.
3.) Read the vertical length (in millimeters) automatically inserted by LOGIQworks in the other box in
the center at the bottom of the screen and use the monitor's controls to set the lengths of the vertical
lines equal to each other and to the value given by LOGIQworks.
4.) For a multi-monitor system, repeat the process for the other monitors in the system.
If you are calibrating a multi-monitor system, the monitor calibration screen will first appear on your top
