ADV7480 - Compatibility Issue

Hi , 
We met two kind of situation, one is no display on screen, the other is to display abnormally. 

1. Laptop -> Apple Type C to HDMI adapter ->  HDMI input to ADV7480 -> SoC -> Display on screen 
Test result is that there is no display on screen.



2 Apple Laptop -> HDMI input to ADV7480 -> SoC -> Display screen
Test result is that display isn't stable. . 



Other Windows NBs + Apple adapter : Always Fail

Apple NB + Apple Adapter: Always Fail

Other Windows NBs + other adapter : PASS

Apple NB+ other adapter: PASS

Apple NB connect to ADV7480 with HDMI input :  Fail rate is too high.



Is there a compatibility issue between Apple products and ADV7480? 
Is there suggestion or register can adjust this situation? 

Thanks.
