    we are using ADV7611 and ADV7511W devices in our demo board. To bring up both the devices we are just loop backing RX to TX in FPGA. The bringup scripts configure the RX and TX for RGB, 24-bit with separate sync.


we are seeing the color contour on the display, tried by tweaking the ADV7611 registers but not succeed.


HDMI Tx alone tested with pattern generator and video streaming from the different source path, there is no issue at all. the ADV7511 is configured for RGB, 24-bit, seperate sync, no CSC enabled.


please help us to resolve color contour issue.


please find bringup sequence and image in attachment.
