Daisy-Chaining a DVI Monitor on a Thunderbolt Display? I currently have a mid-2012 MacbookPro that is connected to a 27" Thunderbolt display. I also have a 17" Samsung Syncmaster that only has VGA &amp; DVI port on it. So I bought the MiniDisplay-to-DVI converter and tried hooking it up to the TBD's thunderbolt port. 

It didn't work. The TB port doesn't recognize the monitor at all. When hooking the monitor up directly to the MBP, it seems to work fine. Are there compatibility issues when using the MiniDisplay-to-DVI converter?
I would just like to chime in here and note that it is possible to get that DVI display to daisy-chain, but the caveat is that you have to put another Thunderbolt device in between the Thunderbolt display and the Mini DisplayPort->DVI converter.


  Apple's notes one other caveat about the Thunderbolt display: older
  Mini DisplayPort displays won't light up if they're hooked directly
  into the Thunderbolt port on the newer LCD. Macworld's testing found
  that Mini DisplayPort LCDs can be added to a Thunderbolt chain and
  work as normal by hooking them into another Thunderbolt peripheral.
