Q: 1. Hey do you guys know If I can use this on a thunderbolt display? To a standard z97 pro motherboard?

A: I use it to connect a thunderbolt to GTX 770 so I suppose yes

Q: 2. Can you Daisychain this to 2 thunderbolt displays?

A: Thunderbolt displays require an Apple Thunderbolt port to work. They work exclusively on a Thunderbolt data signal, not just a video signal. This adapter only convert a video signal to a video signal. The form factor is the same for Thunderbolt 1&2, but the data being sent is much different. This adapter is perfect for using an older Apple Cinema Display that has a Mini DisplayPort, and connecting it to a video card or computer that only has Displayport (such as Nvidia video cards, or HP computers). I am using it for that, and it works perfectly. Hope this helps.
