Two Thunderbolt Displays not working under Windows 7

Very interested on the subject as i was thinking of buying two extra monitors to play iracing on my iMac27 via bootcamp... Looked everywhere, couldn't find much light. Any news from you guys?

this is working now. My iMac 27 has an external thunderbolt and an external hdmi monitor using thunderbolt adapter and all three monitors work in both lion and windows 7

I should give it a try if i can find some monitors to test... Would other plug types work, other than the hdmi?

Has anyone had luck getting multiple Thunderbolt displays to work with Bootcamp? I have had the same issue as everyone else and after investigation discovered that Apple had not written a driver for Bootcamp to recognize the dual TBD config. I have since written to Apple requesting this support but no response has been received.

Come on Apple.............Please make this work!

I've read that Parallels will solve the problem.

Why do you need two Thunderbolt screens??

Use 1 Thunderbolt display (for USB hub and LAN connection), and then use 1 Cinema display as the 2nd screen. You can chain the USB ports, but not the displays, so you do have 1 extra connection to the MBP, but that's fine.

Windows 7 will (natively) drive this setup without problems.

Parallels doesn't solve the problem at all. It just avoids it. The problem is that if you boot into Windows, you can't drive two thunderbolt displays. Parallels avoids it by letting you boot into OSX and running windows in a VM. You get to use your two displays that way, but at a pretty steep price. Parallels works ok, but it's nothing like native performance.

I sorely wish Apple would update the Bootcamp drivers for this scenario. It's been a problem for at least two years, by my reckoning.

Again, you don't really need two Thunderbolt displays, you need one to act as the "docking station", giving you an ethernet plug, then you can "fill up" the rest of your needs with Cinema displays.

Windows can run multiple Cinema displays natively on the MacBook Pros, so 1xThunderbolt Display + 1xCinema Display works just fine.

Would there be a compromise in navigation speed or display quality if the daisy chain + cinema display set-up is used? Would it work also for iMac?

Thanks

Bought a new MBP and TBD one month ago. Running parallels as vm. TBD display ports have never worked properly. Second display and second MBP, same result. When I start up there is no power to the USB posts. Apple USB keyboard will not be recognized. Apple has been supportive but after 4 trips to Genius desk, about 40 hours of AppleCare and Joint venture support we still have no solution. Problem seems to have become worse. I was able to unplug and replug keyboard repeatedly to get it to work in the TBD. Now it will not work at all. Losing money daily with this problem and may need to go back to PC regrettably.

I have the MBP Retina 15, w Apple Thunderbolt 27 Monitor and Apple LED 27 Monitor. Everything works fine if you have a thunderbolt peripheral (Disk drive etc.) between Monitor 1 and Monitor 2. Don't ask me why, I couldnt tell you. It just works. Bootcamp side, same deal, it wouldnt work till I put a TB peripheral between the two. Now works like a champ.

Thunderbolt Monitor has Thunderbolt port it must be closest to MBP. LED Monitor has displayport only must be last on chain. Disk Drive is Pegasus R4 w 4 4TB Drives. Also MUST use Macdrive Pro as it is only Windows program to recognize Apple RAID on Pegasus. For whatever reason did not work when monitors daisy chained directly together w/o Disk Drive in between (one screen always blanked out irrespective of where placed in chain).

FYI: Also worked w Belkin Thunderbolt Dock in between monitors. Have not yet tried TB Monitor then Belkin then Pegasus then LED. Will attempt this weekend and let you know. Also, running Mavericks on Mac side and Widows 8 with Classic Shell on Bootcamp side w/ Nvidia update if that makes any difference. Don't know the tech behind it, just trail and error.

Just resolved this isseue. This is actually a problem with the NVIDIA driver, NOT Windows like some have suggested. If you goto your display settings, you will notice that the second thunderbolt screen (or third display, including your laptop monitor) is grayed out. This is due to it being disabled by the NVIDIA driver. To resolve this issue, simply:

1. Right click on the desktop
2. open NVIDIA Control Palnel
3. Click "Set up multiple displays" (under Display)
4. Ensure that all displays have check boxes in them
5. Hit apply
6. Job done.

The third display will now be available to configure via the usual Windows display options.

Tom, can you describe your setup, hardware configurations, and connection details? I have 2 Thunderbolt Displays and in the updated NVidia driver control panel, the 2nd Thunderbolt doesn't show up or is greyed out. The laptop and 1st Thunderbolt display shows up.

I bought a LaCie Thunderbolt drive that has 2 Thunderbolts that I'm going to try putting in between the two displays in the chain like Rick, but the only difference is that I have 2 Thunderbolts compared to his 1 LED display at the end.
