How to connect Surface Pro 6 to Apple Thunderbolt Display 27"
Unfortunately, you can't connect Surface Pro to Apple Thunderbolt Display as @jksoegaard suggested because Thunderbolt Display can be connected to thunderbolt port only. Trust me, I have both, I've tried, it's not working and it makes sense it doesn't. When Surface Pro comes equipped with thunderbolt port instead of miniDisplay Port, it should be possible, but right now, it is not.
