Displayport 1.4 rx only example

HI,

Is Displayport 1.4 rx only example working functionally?

I'm using zcu102+FMC with this example, vivado 2020.1, but when I connect rx port to DP source, there's just an abnormal monitor device shown up, and only in device manager, the XLX0123 device name is been recognized.

Hi @furball 

 

It seems vendor specific name like EDID on DP Tx.

Would you make sure connection ?

Hi @watari , @kshimizu ,

After changing to another dp source, the operation went normal. But I guess it’s related to compatibility, cause I’ve used both source with pass-through example and nothing went wrong. Any suggestion about compatible problems?

Hi @furball 

 

It seems driver issue about parsing EDID on DP source device.

Would you update NVidia's driver ?

Also, would you try making sure protocol by ex. DP analyzer on DP AUX channel, if possible ?
