  • Mac Pro Graphics card (W5700)

    I have a 2019 Mac Pro with a Radeon pro W5700 Graphics card. Works fine with my 2x BenQ monitors (Connected together as a 2 monitor set up) I also have a JVC U31 professional monitor which has an HDMI Input on it. If I connect the HDMI (Or Thunderbolt) outputs on the W5700 to the JVC – the display comes to life for 10 seconds then reverts to a green only image. I’ve checked the HDMI with an output from my BMD 4K Ultrastudio and it works fine. Just doesn’t want to know with the Radeon output. Any one know what’s going on? It can’t be HDCP handshaking surely? Any one know of a way of turning this off?
