Horizontal Total Pixels	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 direction.
Active Pixels	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).
Horizontal Start	number of pixels between the beginning of the input signal and the start of the video information in
	the signal.
Horizontal Period	already filled in with the correct value when active file.
Vertical Total Lines	already filled when an active file is selected to be edited
Active Lines	number of horizontal lines determining the height of the projected image. This value is normally given
	in the specification of the source. If not, adjust until full image height is displayed (no missing lines)
Vertical Start	number of lines between the start of the input signal and start of the image on the screen.
Interlaced [On] or [Off]	this selection is automatically filled when active file has to be edited. If the image is wrong due to
	mismeasurement, use the ENTER key to toggle between [On] and [Off]. (for interlaced images,
	1 frame contains 2 fields).
Read AMDS	AMDS = automatic mode detection & synchronization
	During the installation of a file with LOAD, the system automatically measured the horizontal period,
	the total vertical lines and the interlaced mode. When selecting Read AMDS, the system remeasures
	the above indicated items.
