How to enable third monitor in Macbook Pro 15'' mid 2015 model? I have Macbook Pro 15'' and have 3 external displays that I want to connect to it. However when I do connect to it using these ports:


HDMI
HDMI to thunderbolt adapter
DVI to Thunderbolt adapter


All three monitors have a maximum resolution of 1920x1080. 

I am not able to see one of the monitors. It is no specific monitor. It is the one I end up connecting last. If I restart into Windows I am able to use three monitors. What can I do to fix this?
Apple doesn't support this configuration.    Per the Apple specifications, you can support up to two external monitors:


  Dual display and video mirroring: Simultaneously supports full native
  resolution on the built-in display and up to 3840 by 2160 pixels on up
  to two external displays, both at millions of colors
