The CVT/GTF Method
GTF and the newer CVT are a standardized approach to creating video formats.
To select a GTF format the user must input Active Pixels, Active Lines, Frame Rate and the margins
flag, then click the GTF button . All other fields will then be filled in with the nearest suitable GTF video
format.
A CVT video format is similarly selected. However CVT also supports the reduced blanking flag.
Reduced blanking allows LCD panels, which do not require as long a blanking period as CRTs, to
support a higher resolution for any fixed maximum pixel clock rate.
After a suitable video format has been created and tested it can be saved to non-volatile storage by
clicking on Save Formats. This video format will then be available after a device reset or power cycle.
Unwanted user video formats can be deleted by selecting the video format to delete and clicking on
Delete. A Save Formats operation is then required to delete this format from non-volatile storage.
