I ❤️ the little haptic responses on my iPhone 7 under iOS 11
The caveats right now:
1. The USB ports (and all of my devices connected to the display, including my FiiO DAC) aren't showing up;
2. No 10-bit colour - I'm not sure if this is my GPU or a DisplayPort limitation;
3. No brightness control (this is going to be a showstopper, I think).
I've installed a Thunderbolt 3 card in my Hack Pro, and now it can drive the LG 5K display. It doesn't see any of the USB ports on the display yet, but this is a good step forward!
