Noise in the DVI Output of ADV7511W


We are using ADV7511WBSWZ for DVI Output in our board. The set up is as shown in the attached image.

The cables used for connection are shielded.

We have observed that, there are white blinking dots on the output (On Monitor).

We tried to display only one primary color(any of the three) bar on the screen, with darker color the dots are not visible, but with lighter shades of the same color( with mix of other two primary color) dots are visible.

Have anyone have come across this kind of issue ?

Please help us to solve this issue ASAP.

Thanks & Regards,
