Does anyone know if you can tether 1 Thunderbolt enabled new Apple Display to an Old Non-Thunderbolt Apple Display ?

TB-->Non

Seems like it should be doable if apple made it backwards compatible with the old cords, right :confused: You just can't go from Old->new to tether..

or did they change it up completely ???
 
Tethering monitors? I'm not sure I understand. What are you trying to do? What hardware do you have?
 
I'm not sure about that but I think it should work.

TB output -> TB ACD -> non-TB ACD.
 
Yep, done posting after that trollish reply. Bye.

....

He isn't talking about phones, he's talking about literally using a cable to do Thunderbolt pass-through, which is a new feature built into the new 27" Thunderbolt displays. I saw the thread earlier, but I am unsure of the answer, although I have seen the question elsewhere.

I assume the op is asking this question in order to save a few hundred by only having to buy 1 Thunderbolt display and 1 Displayport display.

Yes, this.

Can you go from a Thunderbolt Mac to a Tunderbolt ACD, and then to a Displayport ACD.

Thunderbolt will do it for sure with two TB displays, but there's no definitive answer on hanging a DP ACD off a TB ACD.
 
But not with the new Macbook Air, which has a cut down TB controller that only supports 1 display.

It's not the Thunderbolt chip's fault. The integrated GPU in the Core i5 / i7s is not good enough to drive 3 displays.

Its sounds like both. The new smaller and cheaper Thunderbolt chip has half the channels and Intel 3000 IGP only supports 2 displays anyway.

However what if you wanted 2 externals displays and have the laptop's display off? It would be a total of 2 displays which the IGP should be able to handle.
With the MBA it doesn't sound like this would work, but what about the MBP13. The MBP13 has the 2 display limited Intel IGP, but the full version of the Thunderbolt chip.
 
I think you mean Daisy Chain, not Tether.

No one knows for certain if you can Daisy Chain from TB Display->DP display.

But it seems like there would be a fair chance unless the output on the iMac/mini/laptops are non standard TB that are special versions with additional graphics support or if the all TB in the system are equivalent.

Yeah, Daisy Chain :)

TB Display -> Non-TB Display

Would love to know that when anyone finds out - determines if I need to sell one and get a new one or not :D :D
 
Your answer is no daisy chaining a DP display onto a TB display.

BUT, it will work if you have a thunderbolt device (like a disk drive) in between the displays. Lord only knows why.

Apple must have left that bit of electronics out of the TB Display.

Pretty shitty IMO.
