I have spent hours trying to make all the ports of my HD 7850 (two mDP, one HDMI and one DVI) and HD 7870 (two mDP, one HDMI and two DVI) work with Mohave 10.14.4 but I could only get the two mDP ports work using a mDP to HDMI adapter and a mDP to DVI adapter. Is there any way to make the video card HDMI and DVI ports work without the use of a mDP adapter? Or am I wasting my time trying?
