hi David , in the schematic you provided the sink and source looks opposite is it true? if not how is it possible that the source side is the output of the repeater?

in my design , i connected the source side (the gpu) to the input of the repeater and the sink side (Monitor) to the output of the repeater.

i have a problem that when i connect both sides i get only black screen (i do hear the detection of the cable).

Hi,

Can you please share your schematic?

In the DP120 reference schematic, when it says Display_Port_Connector_Sink, it means the connector pin mapping is a sink pin mapping connector that needs to be connected to a source. And when it says Display_Port_Connector_Source, it means the connector pin mapping is a source pin mapping connector that needs to be connected to a sink.

Thanks

David
