Hi PMice
Thanks for reaching out.
Based on your description, we’ll need additional design configuration details to proceed with debugging. However, I noticed that you’ve submitted a similar debug request in the APS platform, where there is already an active discussion.
Since you’re receiving dedicated support from our SME Application Engineer in APS, do you still need assistance on this forum? If this is a duplicate of the APS case, I suggest we close this thread and please continue the discussion in APS.
For your reference, you can use our DisplayPort bandwidth calculator tools to verify the total available link bandwidth and ensure it meets the video requirements.

Please let me know if you have any concerns.
Thanks.
Best Regards,
Ven Ting
