Well done.Just got it all together. It works!
ACD #1 plugged into Sapphire pulse RX 580 8GB DVI port
ACD #2 plugged into genuine Apple Dual link DVI to Mini DisplayPort adapter. That adapter is plugged into a Cable Matters Mini DisplayPort to DisplayPort adapter. That’s plugged into DisplayPort #1 on the RX 580.
They don’t make this easy!
Thanks. Not sure where I got it. I've had it on my computer since my 1,1 days with dual 20" displays. Multi monitor wallpapers from the App Store is great!Well done.
and I love the desktop image.
...or if you don't already own the card but have to make a purchase decision and do not need the last bit of RX 580 performance for all cost, just get the ASUS RX 570 ROG Strix OC 8GB, which is barely 10% slower than the 580 with all the other goodies of a (relatively) modern AMD GPU, but comes with two Dual-Link DVI ports and as this can drive two 30" Cinema HD displays at full resolution out of the box.This is how you get a second display to work properly through a Display Port. Use an OEM Apple DVI to mini DVI adapter.
