Dear all,

My customer want to know if there is any way to confirm if the PSR function is working normally or not? Could you please help give your recommendation?

Thanks.

Hi John,

You can check whether DP Main link is actually turned off.

Regards,
Joel

Hi Joel,

Could you please further explain how to check the DP Main link is turned off or not?
Which register we should control or what steps we need take to implement it?
Thanks.

Hi John,

I meant, monitor physically the DP link to confirm that this is turned off. Another option would be reading the state of the VSTREAM_ENABLE bit and checking that it stays 0 and the panel keeps displaying.
