Our customer is having questions for ADV7619. They have some monitors that can use RXA_5V. And some of the monitors they are using can not use RXA_5V. However, they have to use both monitors when HDMI cable connect to the monitors. Therefore, they propose the following methods.


[1] Monitor CABLE_DET_A_RAW and switch between DIS_CABLE_DET_RST0 or 1.

   (a)CABLE_DET_A_RAW =1(Detect 5V


   (b)CABLE_DET_A_RAW =0Not detect 5V



[2]   Set DIS_CABLE_DET_RST1 all the time when they use RXA_5V and don't use RXA_5V.

Is it possible that this method as above [1] or [2] run ADV7619 correctly?

Also, Could you tell us anything if [1] and [2] methods can't be used?
