Help me here, as I'm finding my thunderbolt station less and less useful.
Late '13 rMBP. I just bought a Samsung U28D590D (4K), and it´s a delight to use with OS X. Now I have a 28" retina display. 🙂
I know TB station can't power 4K displays, it would need TB 2 / DP 1.2 for that. However, I'm trying to power a 2nd external display (an old 17" 1280x1024 LCD) via HDMI, and I find it impossible to power both displays at the same time when HDMI cable is connected to thunderbolt station HDMI port. However, it does work fine when connected to the rMBP HDMI port!
Is this normal?
I already have to connect 2 cables (displayport for 4K monitor) and thunderbolt for TB station, I really could use TB station HDMI port for the 2nd monitor...
