Random Access Adjustment Mode
Vertical refresh [sync/async] : The way of updating the image
information on the LCD panels.
* 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
artefacts'. 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 syncronous mode is default, for all other sources
below 60 Hz asyncronous 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.
Vertical sync polarity : [leading] or [trailing]
The vertical refresh can be synchronised with the leading sync edge
or trailing sync edge. Default on [leading].
Toggling to [trailing] is only necessary for special applications where
the trailing edge of the sync signal has to be taken as a reference.
Use the ENTER key to toggle between [leading] or [trailing]
Press EXIT to leave the Edit File Option menu.
