So I'm using the Lg UltraFine 4K hooked up through USB-C and a Lenovo 2K display hooked thru HDMI. For some reason whenever I go to watch Netflix or Hulu on the 2018 Mac mini it gives me a HDCP error about the HDMI not being 1.4 compliant. The LG UltraFine is set as my main display and I keep the Lenovo turned off unless I use it. The only way Netflix and Hulu are working is if I unplug the HDMI cable from the back of the Mac mini. This also only happens when using Safari. Is there a way to fix this issue or is this a known problem?
