Hi,
I am creating a PCB with CYPD3120 And would like to use display port with only 2 lanes.
I already have a discussion relating to such topic but would love other cypress engineers to help since Pranava is on vacation.
You can find our discussion here:

Would realy appreciate your help using the CYPD3120 with only 2 lanes of SS.
Best regards,
Ido

Hello Ido,
1. MTDP DFP_D_CONFIG_D and DFP_D_CONFIG_F should be supported by HOST (Notebook or desktop).
2. Set preferred DP Mode : Multi-function DisplayPort in Ez-PD configuration Utility.

Lisa

Hello Ido,
Typically, the most easy way to test MFDP and 2 lane DP is using Macbook or latest Type-C Notebook.
The 2 lane DP + USB3.0 defined in Type-C Alternate mode is UFP_D pin assignments B and pin assignments D for DP dongle or UFP role. The DFP_U typically adapts DFP_U pin assignment D, or all of DFP_U pin assignments is supported.
If you could like to debug further, please attach PD log in this threads.
Best Regards,
Lisa
