How do I get the Startech Thunderbolt 3 to DisplayPort adapter TB32DP14 to work?

Hello @modesitt,

Thank you for your reply.

Based on the information you have provided, having tested TB32DP14 with multiple models of
laptops we would expect to be compatible, we would recommend replacing the unit under our warranty.

 We will be reaching out to you directly with next steps for replacing the product.
