I was reading this topic and wanted to reply there but its closed:
I am having the same problem
My board as you can see in my profile can boot into Uefi and legacy.
I was with high Sierra a long time but because I purchased new effects for FCP I need to upgrade to Catalina.
I have a Nvidia GTX 650 and saw this is not any more supported in Catalina OSX so I got the Sapphire Pulse Radeon RX580 8GB DDR5
So yesterday i removed the old graphic card and tried to setup High Sierra again.
But even in high Sierra it will not show, I see the loading and than a flash and it turns black with the display on.
Tried recovery.
So if I do understand I need to purchase 2 display ports to VGA in order to get it running?
Or is there another way, now I did the connection with 1 DVI and 1 HDMI or would it be better to just buy 2 displays with a Display port?
I have a GA-Z97X-UD3H Gigabyte board
I7 8 core (i7-4790 cpu @ 3.60GHz)
Board bios has only IGFX option
Than 3 ports and PCI option.
Mem is 32 Gb DDR3
In windows 10 the Sapphire is working normal
Would it be a better option to buy a new SSD and to setup Catalina from scrap?
This with a setup of the internal 1 display intel and after to connect the Sapphire?
Anyway I did order the adapter DP to VGA but I am very remote and will take some time before it arrives so any suggestion would be great
Upgraded to RX580, screen goes black during startup
Ok! I couldn't get my hands on a monitor with a display port input but I was able to obtain three display port to vga adapters and they work!!!!!!!!!!!!!!!!!! I'm doing a happy dance!!!!!!!!!!!!!!!!! Ed thank you thank you thank you a million times!!!!!!!
