ADV7611 does not sync as programmed

I have programmed the ADV7611 to show a resolution of 1920x1080. My edid file is the edid-test.dat shared by you, Analog Devices, in the engineer zone.

 

I probe the vsync pin in my adv7611 eval board and I get inconsistantly 60Hz.

I have attached a picture shown in my scope.

 

I have tried Prim_mode = 0x05 and vid_std 0x1e as shown in the UG-180 without success.

 

Any recommendations?
