(1)The input signal is 20bit  YCrCb 4:2:2 and the 480i720p1080i can all displayed on the monitor successfully  but the 1080p can not . I detected signals and clock on the TMDS line but the monitor is not displaying an imagethe monitor is able to display 1080p60)),the monitor promotedunsupported signal please check your device output

Whether AD9389BBCPZ-80 can support 1080p60? Some AD9389BBCPZ-80 can display 1080p(60)on the monitor on my PCB board and some can not.

I also tried  neither AD9389BBCPZ-165 nor AD9889BBCPZ-165 can display 1080p(60) on the monitor

I don’t know why ? how can I do that the AD9389 can display 1080p(60) on the monitor ok?

(2)The other question is about ADV7441 ,  when I power up the ADV7441,there is no signal output from  the  I2S  some  time
