External monitor not working with Blackmagic eGPU (NEC PA311D - iMAC 27)
I try to connect my external 4k monitor to iMac through blackmagic eGPU. iMac detects monitor properly and shows it in configuration panel as external display with all parameters. Unfortunately I see only black screen, although indicator light is on and backlight lights up.
When I connect monitor directly to iMac it works properly.
I have tested this configuration with my MacBook Pro (Retina, 15-inch, Late 2013 ) and it works properly. Can someone help me? Please!
My configuration is:
BlackMagic eGPU Radeon 580pro
External monitor: NEC PA 311D
