Hello,
I have a Mac Pro 5,1 running High Sierra with dual Apple displays (20" and 23"). Video card is an MSI branded Nvidia GeForce GTX 650. I can't get both displays to turn on/off with the main power button - one of them must be turned on/off manually. Both monitors are connected via DVI. Is it possible to do this? I have swapped ports. It is the case that it's the 20" that always must be controlled manually. I could be mis-remembering, but I thought that I was able to do this on a previous 1,1 I owned, with the same card and displays.
Thanks!
