Source number
The source number of a non-active file can be changed to any other source number. This makes it
possible to create a file for future source numbers.
Clamp position
Clamping determines the black level of the signal. The clamp pulse can be related to the leading or
the trailing edge of the sync pulse. Use the
ENTER
key to toggle between [leading] and [trailing].
Clamp delay
The time between the leading edge of the clamp pulse and the locked edge of the sync pulse. Can be
any value between 0 and 255. Change the value by pushing the cursor key

Clamp width
The width of the clamp pulse can be any value between 0 and 255. Change the value by pushing

Field polarity
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].
Field select
Default [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].
Vertical refresh
[sync/async]
The way of updating the image information. Not available for PAL-NTSC-SECAM sources. This
option will be 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 incoming 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, 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 that 60 Hz : the vertical refresh is different than the
vertical frequency of the incoming source. Synchronous refresh cannot be used.
