Get a display capable of displaying 720p60 or an Image Pro HD, program a DVI detective with the EDID information.

Set Catalyst Video Input to look at the Decklink Intensity at 720p60 and off you go... No deinterlacing required (which effectively reduces the resolution), and RGB...

Just a thought...
