Hello I just bought a sapphire nitro rx580 8gb and I installed it on my 2010 mac pro and I'm having an issue where windows does not display a picture on my monitor. It reads on mac os but not on windows. I even changed the start up boot to boot camp windows. And nothing shows up. I put the original graphics card ATI Radeon HD 5770 and the rx580 8gb at the same time and still nothing comes up. The original graphics card works no problem on mac and windows 10. Even tried to install windows again and couldn't as nothing displays on my monitor. Is there any way I can use the rx 580 on windows?
