Hello everyone.
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:
iMac 27" late 2013
GeForce GT 756M 1GB
Intel Core i5
macOS Mojave 10.14.6 fresh installation (I tried on Catalina as well with the same result )
OS patched with purge-wrangler.sh
BlackMagic eGPU Radeon 580pro
External monitor: NEC PA 311D
iMac<>eGPU - Thunderbolt 2 cable with Thunderbolt 3 adapter
eGPU<>PA 311D - Thunderbolt 3 cable
To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.
