I have an entry level 2017 iMac Pro running Mojave 10.14.6 which is connected to
an Apple USB-C to HDMI adapter, which is connected to
an AmazonBasics 15ft Premium HDMI cable (18Gbps) which is connected to
a 2018 Vizio P-Series 55" screen
Despite the fact that each link in that chain supports 4k at 60Hz, when I check the system information on the iMac Pro, it shows that I'm only displaying at 30Hz:
How can I get the full 60 Hz refresh? What am I missing?
