Hi,

We are able to resolve the issue in ZC706, problem is we need to use clock as 148.5 MHZ for 1920 X 1080 @ 60 Hz Resolution.

Hello @rajeshkhanna 

There is limitation with ZC702 HDMI Codec innterface. Only 16-bit of Video Data lanes are connected for ADV7511 IC. So, ADV7511 supports 1080P 60Hz, YCbCr 4:2:2 encoding via 16-bit input data mapping on ZC702 board.

While YUV4:4:4 data type requires 24 bit Video data lines.
