If the value for "Horizontal total pixels" is wrong, sampling mistakes
(small vertical bars in the projected image) will be seen in the image.
Select "Total" and adjust the pixel quantity. Adjust for zero bars (hint:
if the number of bars increase, adjust in the other way).
The "active pixels" : determine the width of the window on the screen.
This value is normally given in the source specifications. If not, adjust
until full image is displayed (no missing pixels).

input signal and the start of the video information in the signal.
"Horizontal period" : already filled in with the correct value when active
file.
The "Vertical Total lines" are already filled when an active file is
selected to be edited.
The "Active lines" : number of horizontal lines determining the height
of the projected image. This value is normally given in the specifica-
tion of the source. If not, adjust until full image height is displayed (no
missing lines)
