Lost-Entrepreneur439 Posted Thursday at 09:11 PM Share Posted Thursday at 09:11 PM (edited) I have a PowerColour Radeon HD 7870, and in Sierra and earlier, it works fine, but starting in High Sierra, it only outputs to Mini DisplayPort, HDMI and DVI just show a black screen. Does anyone know how I can patch it? I no longer have a DisplayPort adapter and as this is just a spare system, I'm not really interested in buying another This system is legacy only, I've tried on a UEFI system and it had the same issue.

Harry Betancourt Posted Friday at 09:22 AM Share Posted Friday at 09:22 AM You might want to try using a tool like Clover or OpenCore to patch your graphics drivers for High Sierra, as they can sometimes help resolve output issues with older GPUs.
