Explanation
If the value for 'Horizontal Total pixels' is wrong, sampling mistakes, small vertical bars will be seen
in the image (Total numbers of pixels between 2 sync pulses is used to adjust the sampling rate).
Select 'Total' and increase or decrease the pixel quantity for no bars in the image. (image 16-4)
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). (image 16-4)
This is the number of the pixels between the beginning of the input signal and the start of the
video information in the signal. (image 16-4)
This is already filled in with the correct value at the time of the source identifying.

This is the 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).
This is the number of the lines between the start of the input signal and the start of the image
on the screen.
This selection is automatically filled at source identifying. If he image is wrong, due to wrong
measurements, use the ENTER key to toggle between On and Off. (For interlaced images, 1
frame contains 2 fields).
AMDS = Automatic Mode Detection & Synchronization
Selecting AMDS and confirmed with ENTER, the system re-identify the input source.
Explanation
The source number of a non-active source can be changed to any other source number. This makes
it possible to create a file for future source numbers.
Clamping determines the back level of the signal. The clamp pulse can be related to the leading
or the trailing edge of the synchro pulse. Use the ENTER key to toggle between Leading and
Trailing. (image 16-5)
The time between the leading edge of the clamp pulse and the locked edge of the synchro pulse. Can
be any value between 0 and 255. Change the value by pushing the curser key ↑ or ↓. (image 16-5)
The width of the clamp pulse can be any value between 0 and 255. Change the value by pushing
the curser key ↑ or ↓. image 16-5)
The field polarity function is used for interlaced images. Both rasters of the image could be shifted in
a wrong way (double lines are visible in the image). This can be corrected by forcing the field polarity
to Neg. or Pos. Use the ENTER key to toggle between Pos. and Neg.
Default setting = [Both]
The field select is only used for interlaced images. One frame of an interlaced image contains two
fields, an even and an odd field. The choice exists to project [both] fields on the screen or only the
[even] or [odd] field. This can be useful for 3D projection. Use the ENTER key to toggle between
Both, Even and Odd.
The way of updating the image information on the display panels. This item is not available for
Pal-NTSC-Secam sources, and for that reason displayed in gray.
– For sources with a vertical frequency up to 60 Hz: the vertical refresh rate is the same as the
vertical frequency of the source. This is a necessity to project moving images without 'motion
artifacts'. For stationary images with a vertical frequency up to 60 Hz, it is still possible to use
asynchronous refresh. When loading Pal, Secam or NTSC-files, the synchronous mode is default,
for all other sources below 60 Hz, asynchronous mode is default.
- For sources with a vertical frequency higher than 60 Hz: the vertical refresh is different than the
vertical frequency of the source. Synchronous refresh cannot be used.
