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.

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].
