Hello, thanks for posting and I am sorry to hear that our adapter is not working! We do not have other feedback from customers using the Xiaomi Mi Notebook Pro nor do we have this system for internal testing.
Do you happen to have other USB-C video adapters that are working with the USB-C ports on the Xiaomi laptop?
Unfortunately, I do not have recommendations from a software standpoint and the only thing we can really try is to see if a replacement adapter works in the event that the current unit you have is defective. If the replacement unit also behaves in the same manner then our adapter may not be compatible with the Xiaomi Mi Notebook Pro.
Please let us know if interested in trying a replacement USBC-HDMI adapter and then we will reach out to you directly in order to facilitate the replacement process.
Thank you,
David W.
