A Thunderbolt Display will only work in Windows on a Mac with working Optimus. The performance will decrease since it will run in Optimus mode. There is no adapter to make the TBD work on sth else as a TB port. A CD will work if you find a GPU that has miniDP plugs. E.g. some Gainward cards have miniDP.

Great, thank you, it is much clearer now.

So forgetting the TBD I should be ok with 2 Cinema Displays connected directly to a graphics card on the eGPU box.

I know ATI(AMD) cards have mini-display ports incorporated in their cards for example:

Sapphire R9 380 Compact ITX Nitro OC AMD Graphics Card 4GB

is there something specific I need to look for in the specification of the graphics card so it runs 2x27" Cinema Displays at full resolution and at comfortable (full) refresh rate?

I need the config to run in OSX, not Windows so if you have had some experience could you please share.

Your questions are answered in this thread. Ie:  you can attach the TB monitor to the TB port of the MBA or a TB port on the Thunderbolt enclosure. However, it is not ideal as the data is then being shuttled back via the iGPU across the TB link. The eGPU cannot directly drive the TB display. It's therefore best to acquire a different display that attached to the DP/HDMI ports on the eGPU if wanting to maximize eGPU performance.

Well I am asking about pears and answers are about apples really...

if you read my question, the goal is to drive 2 Apple Displays from a macbook Air. Nowhere in this post i see the answer to this.

I know I can attach 1 TB display to TB port and the question is not about that, but about how to attach 2 of them.

if not thunderbolt maybe just normal Cinema Displays instead? I am looking for a solution which is simple for the end user.

Can a thunderbolt monitor be driven by a mini-display port of a normal graphics card attached to say a standard windows desktop?

and what happens to my threads I am trying to create?

I don't think an eGPU will help your TB Display situation. Can't you daisy chain the TB Displays?

Not on Apple Air, internal GPU is only capable of running one TB display

By the way, I have created a new topic but my post ended up in this thread. I thought I did something wrong and tried to open again and it has disappeared after a while.

If the moderator is  responsible can I know what have I done wrong, as the question is related somehow to this post but not entirely.

I really need to know if anyone had experience in attaching 2 Apple screens to an Air.

Hi Everyone

the goal is to run 2 thunderbolt displays from Apple Air. Natively it isn't possible as only one will run, hence thinking of eGPU route

do you think this will work and if so, which minimalistic graphics card is best to run purely for display purposes (no gaming) as gaming one would probably be GTX970-980

thanks
