ADV7623 output flicks

Question

Hi EZ team, 
 
 I connect the Android player with a resolution of 1440 * 90 to the ADV7623 who is then connected to the projector. The final output screen will flicker and cannot be displayed properly. 
 
 If this Android player is directly connected to the projector, it can work properly, even at 1920*1080. 
 
 If I connect a laptop with a resolution of 1440 * 900 to ADV7623 who is then connected to the projector, it can also work properly. 
 
 To better describe this problem, I draw a picture below. 
 
 Is this a problem caused by the configuration of ADV7623? Could you please give me some suggestions? If more details are needed, please let me know 
 
 Many Thanks! 
 BR.

Hi, 
 Flicker means, It seems HDCP issue since ADV7623 can have capability to support HDCP 1.4 but from the above picture Android player seems to be an HDMI2.0 device so it will start authenticating with HDCP2.0. 
 If Possible, Could you please share the debug log so that we can identify the exact root cause when using Android player as an source. 
 
 Thanks,
