Hey,
I have installed Windows 10 on my MacBook Pro Retina Mid 2012. I'm using 2 external Displays, but the Thunderbolt Display show's only a black screen. All ports (USB, FW, Ethernet) on that Display work fine. I have updated all software.
MacBook Pro (Retina, Mid 2012), Windows 10, Thunderbolt Display
Let me test this configuration using MacBook Pro (13-inch, Mid 2012) - Technical Specifications and a Dell with HDMI.
Are both your external displays Thunderbolt?
the other display is a LG stock 24" Display using with HDMI.
Does the TB display work correctly if you reboot W10 with both displays already physically connected?
The LG works correctly but the TB Display stays black (the ports works). On MacOS, all displays work just as they should.
If you disconnect the LG, and reboot W10 does the TB display work?
Tried it too with everything plugged out.
Thanks for your efforts. Maybe I will try and install Win10 new.
As a test, can you install W7?
Can I install 2 Windows partitions and does my W10 Key work for W7?
You cannot install two partitions. Try your W10 key on W7, but it may not work.
I will try to install WIN7 on a external FW HDD.
Be careful with the external installation. It can bring up new challenges.
I installed W7 on the internal HDD but the TB Display still is pitch-black (again every Port and the FaceTime Cam is working). Everything is updated, but maybe my rMBP is just too old?
I have the latest nVidia driver. Don't know the exact release but the nVidia Software says it is the latest.
