I started this question with my original post: ADV7627 RGB 4:4:4 Color Space Issue 

Colorspace continues to plague my system and I am looking for some guidance. I have spent a considerable amount of time looking at the AVIAPI routines but there are some concepts that aren't quite clear.

Q1:  Does the switch automatically recognize the colorspace then do whatever is necessary to send out the colorspace in the same format?

Q2:  Sometimes the image does not look correct on the output display (sync). Is this because the display does not support the colorspace and encoding format of the source device?

Q3:  By default, are the AVI InfoFrames passed directly and automatically from the source device to the sync (assuming no errors in the packet checksum)?

Q4:  If the source device obtains the color / format capabilities from the sync via EDID, why would we ever have issues regarding color processing? 

 

I appreciate the discussion on this issue.
