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 on the LCD panels. 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.
Film mode detection:
[On] or [Off] Detects in the [on] mode if the source is film or video. Use the ENTER key to toggle between [on] or [off]
