So i bought this one and thought it would work out of the box. I was wrong.
After few days i managed to stabilize my 10.14.2 and now it works as it should - actually it runs fantastic, faster than ever, except this bad boy.
What seems to be the problem?
i cannot work with 3 monitors
i cannot send a 4th display to my TV to watch movies
as i did for the last two years with my GTX970 and sierra/high sierra
The symptoms are kinda strange. i don't think it is a settings problem but then again i don't know. After lots of testing i settled with watevergreen "on" and nothing else. no injectATI or orinoco framebuffer. On the 2 working monitors it seems the best solution.
So i went on and made a little table of the results of my tests.
first examples are straight forward but the last two is where strange things happen.
As soon as i plug in the 3rd DVI or HDMI monitor the 2 working screen immediately get a shade of grey and freeze at place. This means that you can see the last things displayed but with a grey shade on top.
And strangest of all, the mouse cursor still works! You can do absolutely nothing except moving it, but it works.
This last one is the big difference in 10.14.2. In 10.14 and 10.13.6 i only had black screens
i really don't know what to do.
EDIT: i tried booting with iMac14,2, iMac18,3, Macpro5,1, Macpro4,1, Macpro3,1. All the same except 3,1 where it wouldn't boot at all.
