To create a Custom Source Mode…
n
Using the Name listbox, select a
source type similar to the input source.
This will act as a template on which
your custom mode will be based.
p
If it is an interlaced
source, tick the
Interlace box. For
progressive sources
ensure that this box
is unticked.
q
Copy the monLineCount value (in the Device Status
section) to the LineCount field.
Copy the monLinePeriod value (in the Device Status
section) to the LinePeriod field.
o
Click the New Source button and
enter a new name for the new
source type in the popup box:
r Select the new source name in the mode pull down. This
forces auto-detection to always choose the new mode.
Click Resync to force the auto-detection algorithm to
select your new mode.
s
If necessary, modify the HSize and VSize fields
to be the same as the digHSize and digVSize
measurements. These will only reflect the true
source values if the screen is showing content
across its full extent.
If necessary, modify the FirstPixel and FirstLine
fields to be the same as the digFirstPixel and
digFirstLine measurements.
t
Iteratively modify the
PixelsPerLine value and click
the Resync button.
When the value is correct
sampling across a line will not
show any aliasing. This is best
done using a moire test pattern
or with a screen of fine text.
