Yes I did. I’m connecting my Ultra Studio Mini Monitor to a Asus Deluxe X99 ii motherboard that comes with a Thunderbolt 3.0 PCI card. The onboard Thunderbolt 2.0 looks alike is only a display port that connects to your graphic card. Since my Ultra Studio Mini only has a Thunderbolt 2.0, I had to purchase a thunderbolt 2.0 to 3.0 adaptor to connect to my Thunderbolt 3.0- PCI card. I bought mine from cable matters. It’s not cheap. When all of the physical connection is done, if you’re running Window 10, you need to “Disable driver signature enforcement” under the Advanced Options / Startup Settings otherwise your Ultra Studio Mini won’t work because it will be blocked by Window during startup.
Since I bought my Ultra Studio Mini Monitor before I got a PC, I had to go through the trouble from purchasing an expensive adaptor to use the Thunderbolt 2.0. I will advise you get the Ultra Studio HD mini that runs by Thunderbolt 3 or just get a DeckLink PCI card from BlackMagic if you’re only using PC
