default capture rate to the specified input frequency. It then maintains the aspect
ratio based on the difference between the input active area and the output
resolution (active area) by inserting blank borders around the images. If, however,
you want to fill the entire monitor, you can adjust the input aspect ratio by slightly
changing the number of active pixels and active lines to stretch the image. You may
also need to adjust the number of total pixels.
Adjust the Active Pixels status indicator bar to increase and decrease the number of
active pixels, shifting the starting period horizontally on the screen. Adjust the
Active Lines status indicator bar to increase and decrease the number of lines.
