Hi Jake,

Input is DVI 24bits and separate HS/VS. The goal is to up and downconvert between 1080p and 720p. So you are right, the frame rate shouldn't change but it would seem to me that the clock frequency must toggle between 74.25 and 148.5 - I don't know if this manifests itself as 60/120Hz frame rate that should be converted.

Thanks for the UDX info.
