Dual Monitor GTX770

[dnlx]

Hey guys,

I've got a little problem. On every boot just one monitor is working (it changes every boot, sometimes the right one is working, sometimes the left one). To get both monitor to work I have to power the one who's not working off and on again, after that it's working.

Anyone knows a fix for this?

Did you disable GraphicsInjection/InjectNvidia? Might cause issues like this if enabled...
OS X drivers or Nvidia WebDrivers?

Hey,

yes, I think I did. I installed the nvidia web drivers now, to check if that will fix my problem, but still the same.

Remove inject Nvidia. That worked for me with web drivers and a GTX980.

I don't use inject nvidia.

I disabled inject Intel now as well, because I saw I had my intel graphic enabled in my bios. I disabled that too but still have the same problem.

I mean, it's not a big problem for me. It's just kinda annoying that I have to power off my monitor every time to get it to work. I tried different cables, nothing worked.

And I can't imagine why, because the problem is switching between both monitor, like I said, sometimes it's the left Monitor that is black, sometimes it's the right one.

Did you try to use a different port combination (which are you using at the moment)?

Actually I'm using 2x DVI to HDMI, I tried using Displayport/HDMI, Displayport/DIsplayport, HDMI/DVI, nothing worked.

I'm using this Monitor Dell U2414H http://www.amazon.com/dp/B00GTV05XG/?tag=tonymacx86com-20

Can you provide a ioreg dump? E.g. with

ioreg -l -w0 -p IODeviceTree
