Hi team,
Does the DisplayPort Status register indicate anywhere if the connected device is 2 or 4 lane DP?
Thanks,
Michael

Hi Michael,
If you are using the GUI in debug mode you should be able to read the Data Status (0x5f) which will display the USB connection data and some other information about DisplayPort such as the Pin Assignment which will help to determine if the device is using 2-lane or 4-lane configuration. In addition, the DP SID Status (0x58) register will also give information of the device, if multifunction preferred bit is set as well as the UFPD/DFPD Receptacle/Plug Pin Assignment.
I also recommend reading the DisplayPort Application Note which provides the DisplayPort process in detail.
Thank you,
Hari
