I decided to dual boot my PC and ran into a few problems(Audio, graphics card, iMessage, etc) but everything but this one problem I have got fixed and working. One of the main ones is my graphics card is a GTX 1070 which isn't supported so I bought a cheap GT710 til if or when the 1070 is supported. So I'm using display port from the 1070(For Windows) and hdmi and DVI from the GT710(Sierra). Everything is good now except I only have 2 monitors and a 3rd phantom display is out there that I can't see and sometimes it opens apps to that phantom display which makes it difficult to get to. Question is there a way to get rid of that display without unplugging the display ports? I often go back and forth between Mac and PC.

Build:
GA-Z170x-Gaming 6
I7 6700k
GTX 1070, GT710
Corsair Vengeance LPX 16GB DDR4 3200MHz
 
Any ideas?
 
I'm having a similar issue, and it's preventing me from using a 2nd monitor. I'm running 10.12.3 (just installed today 3/20/17) on a GA-Z77N motherboard with the intel HD4000 Graphics. Pretty vanilla install, I have Clover installed on the boot SSD and the OS is working fine. I have ethernet and audio working like a champ.

But, the OS shows two monitors are present when only one is plugged in. And I believe this is now allowing me to use the 2nd display. I get the following errors in the console window:

It would make sense that the OS is out of sync with the info, the phantom display shows the correct model of the 2nd display but doesn't show the valid state (not plugged in).
