Two Thunderbolt Displays not working under Windows 7

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.

Port TB1 - Pegasus R4 - HDMI Monitor (via a miniDP to HDMI cable)

Port TB2 - HDMI Monitor (via a miniDP to HDMI cable)

Port HDMI - HDMI Monitor (via a HDMI cable)

Did you or anyone ever get this resolved? I had this working at some point and I remember them being daisy chained, but I upgraded Bootcamp and lost my drivers. I believe it was a drivers issue. I have two TD and can get both to work on Mac, but only 1 TD works on Bootcamp Windows 7 side, but I have audio on the 2nd TD while I am in Bootcamp, however no display though. Any help would be appreciated.
