ADV7611 Internal EDID cannot be read on sync clocks

I am using the ADV7611 and followed the script exactly to this thread:

http://ez.analog.com/message/31878#31878

However, I read my vsync (60 Hz) matches my edid, but my Hsync and pixel clock do not match the frequency I programmed my edid for.

I see about 35MHz in the Hsync instead of the 117MHz that I expect.

 

Now, I also have the eval board, follow the scripts HDMI to enconde 1080i, then uploaded the edid, I have the same result except when I plug in the HDMI after loading, then while the HDMI plugged in I force the CP core to free run, then I get 117MHz. I also noticed it had to be in that order to get that result.

My display is a 1080 x 1920 (portrait) so I have set the parameters exact in the EDID DB1 tab of the Advantiv Edit but no luck yet.

 

Please advise.
