Options

Source Number : 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.

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 Width : The width of the clamp pulse [1] or [2] Enter to toggle between [1] or [2].

Field Polarity Inverted :

The field polarity function is used for interlaced images. Both rasters of the image could be shifted in a wrong way (double lines are visilble in the image). This can be corrected by forcing the field polarity to [neg] or [pos].

Use the ENTER key to toggle between [yes] and [no].

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 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.

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]
