not sure. should work no problem. check if card seated properly. otherwise ask around on forums. I have a Pro Tools HD PCI E card (cost $1500) works no problem... although its not the same thing as the black magic card...
I dont think you can use vga monitor even with adapter. Might want to sell that monitor and get a more up to date one. I used to run triple monitors on OSX all the time with few problems. Actually 10.13 has been the best for that since I had 2 4k and 1 1080, sometimes things get weird when its diff res monitors. Now i just run 2 4k monitors bc the 1080p monitor was actually a tv i had connected from the next roomI have been using this build now for about one year and didn't had any crashes yet
Very happy with it.
However, i am using 2 monitors (hdmi + dvi) but recently added a 3rd one (old vga monitor with dvi->vga adapter on my Geforce GTX970).
With the 3rd one plugged in, OSX crashes on startup. Clover boots up, Apple logo shows, but then it restarts.
I tried unplugging my 2nd monitor, using only monitor 1 (main) and 3 (old vga) but then OSX also won't start, so it's defenitely the cause of this monitor. I also use Win7 on another disk and this one starts up fine, can use my 3 monitors all together here. Any suggestions?
True that Malki. Today i connected a 3rd dvi/hdmi monitor to this build and that just works out of the box.
Great!
