Thank you so much for reaching out to us, as well as finding out the issue and solving it! I am glad everything is working.
We advise inside of the instructions that the DVI and 2K HDMI port utilize the DisplayLink chipset, and require the latest DisplayLink drivers to be installed. We also send an automated email pointing to the driver location to download and install from.
Please let me know if you run into any other issues, or have any additional questions or concerns.
Thank you for your patience,
Product Owner & Technical Support
