Macbook Pro (late 2016) suddenly stopped detecting my external monitor after a 3h hibernation Macbook Pro (late 2016) suddenly stopped detecting my external monitor after a 3h hibernation after working flawlessly for two weeks.

I've verified that my monitor works fine with my Windows PC.

I'm running MacOS High Sierra 10.13.6 which I updated to August 18th. 

I'm using a USB-C to DisplayPort cable which will wake up my monitor from standby mode, but my Macbook Pro still can't detect it. Display in System Preferences gives me nothing and Options revealing Detect Screen doesn't yield any results either. 

I've followed the official troubleshooting (including reset of NVRAM and SMC) without results.

I'm guessing that maybe my cable is defective, but then, why would it wake up the monitor?
This was resolved by buying a new cable. This cable was a USB-C to HDMI.
