I just got the two Thunderbolt Displays I had preordered delivered and I was shocked to find out that both of them can not work together under Win 7 on my MBP.
My Set up :
Macbook Pro - 15" i7 - 2011 - with Thunderbolt Port
Two brand new Thunderbolt Displays - One (Display 1) connected directly to the MBP and the other (Display 2) daisy-chained to Display 1.
Mac OS X fully updated, Windows 7 running on BootCamp, also fully updated.
With this set up ... all three screens work with Os X ... Under Windows 7, MBP Display works and Display 1 works, but Display 2 shows a blank black screen.
Surprisingly All three FaceTime HD cameras are deteceted and working. All ports on both displays work and Speakers on Display 1 and Display 2 work ... but no image on Display 2.
Any help appriciated ... I'll be returning these beauties if they can't work on Win 7 because I work on Windows most of the time
I've tried a bunch of stuff already ... Including trying to get windows device manager to detect the displays etc. and to scan for hardware changes.
Apple states on the product page that dual thunderbolt displays are supported on all 15" and 17" MBPs - they don't say anything about dual dusplays not working on Windows 7 and working on OsX ?
I would like to add that I when I updated OsX it installed the following as well:
- Thunderbolt firmware update
- Thunderbolt Display Software
- Thunderbolt Display Firmware Update
... and now when I try and update OsX says that software is up to date, which means all latest firmware updates made available by apple have been installed.
