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 | The way of updating the image information on the LCD panels. Not available for | ||
[sync/async] | |||
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, | |
|
| 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: | The vertical refresh can be synchronized with the leading sync edge or trailing sync edge. Default on | ||
[leading] or [trailing] | [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] |
