Can anyone recommend either an HDMI or mini-DP adapter for the 2017 rMB that actually works? I have tried two now (from Cable Matters and Uptab) and neither one works at all (doesn't even wake up the monitor) with my rMB. The CM one works fine with a coworker's machine (haven't tried the Uptab one). This is happening with multiple displays and they are 1920x1080 so 4k issues are not relevant. Is the only option the Apple adapter? What is so special about the rMB that prevents adapters from working properly with it?
