Hi there!
Please help me about that weird think!
i have a MAC pro 4.1 flashed 5.1 (firmware 144.0.0. , with 48 gb ram and a matched pair of xeon 5690, Mojave OS, no open core.
I buy a Radeon Vapor-X HD7970 GHZ EDITION (not flashed so I can't see the boot screen) and it have a very weird perfomance. let me explain you.
When I start my mac the screen is black while al my periferal works fine. So if I plug and unplug the input a few time ( whether it is the HDMI, or the DVId or the display port) after a number of tries, the screen turn on and all is ok. So it's very frustrating doing everything in that way!
Any thoughts about?
Thanks so much!
