Response from StarTech.com:
Matt, Customer Support
Thank you for your feedback Oleg. We understand your disappointment in the performance of our MSTCDP122DP and we would like to help you troubleshoot. Often, the problem you're describing can indicate that your computer does not support MST capabilities. If you're using a Mac or a computer without MST support we recommend using a standard USB 3.0 to video adapter such as our USB32DP24K60 found here: https://www.startech.com/USB32DP24K60. If you're using a Windows computer with MST support, we'd be happy to look into this with you to help get this MST hub working properly for you. You can contact us at www.startech.com/support where our Technical Advisors are available 24 hours a day, 5 days a week to provide support.
