ADV7441A HDMI input gets blurred in mode 6

In an existing ADV7441A design, HDMI input gets blurred in CP mode 6 16-bit 4:2:2. We checked the output by loop the output data to a HDMI transmitter that connected to a HDMI monitor.

 

By contrast, we first convert to the same HDMI to SDI converter box, and then mux SDI to the same system and loop the SDI output to the same HDMI transmitter that connected to a HDMI monitor. We found the video is much better.

 

So what is the the problem that causes the AD7441A video blurred?
