Height
This allows the height of the video picture to be
matched to that of the PC picture in steps of one
line.
It should be noted that entering values greater than
the total number of lines for the operating scan rate
will not have any effect on the height of the picture.
Note that a preset value is not provided for these
controls. Therefore, pressing the preset button will
have no effect.
Auto Calibration
Auto calibration is a process whereby the
Supervisor LX is instructed to compute the active
area of the PC signal and reposition the video
accordingly.
IMPORTANT NOTE
Before attempting an Auto Calibrate ensure that
the PC has a full screen (non-black) image
currently displayed. A suitable image can be
displayed by opening Notepad, for example, and
maximizing the window. When the Auto Calibrate
has been performed, Notepad may be closed
.

Auto Calibrate?
Yes
To Auto calibrate select

◀
Yes from the Auto menu.
During calibration the normal output from the
Supervisor LX will temporarily be interrupted and
the
Yes
item will become highlighted.
When the calibrate has successfully completed the
text will return to normal.
If the Yes item does not become highlighted when
selected, this means that the Supervisor LX could
not determine the active area of the PC and
therefore could not perform a calibration.
This can happen if there is too much black in the
PC picture and blanking intervals cannot be
differentiated from active picture time.
