    I find al sorts of adapters but none to connect Apple's Thunderbolt Display on my DVI (GTX 680) card. Google didn't help.
    I'm thinking of replacing my display and I don't think it it wise to buy the DVI version in case I want to replace my Mac Pro in the future with something else which will have Thunderbolt.
    Is it possible at all to connect a Thunderbolt display to a DVI?

    It isn't impossible. With enough gyrations most things can be coupled to each other.

    The question of whether the DVI graphics card is forward compatible with Thunderbolt. That's a straight no.

    However, if someone built a powered Thunderbolt dongle with a DVI pass-thru and small computer to drive the thunderbolt switch control logic and the PCI-e lanes then it would work. It would probably cost $150-200.


    That's a highly dubious assertion since the the Thunderbolt connector on a mac is backward compatible with the DVI display.

    The only minor constraint is that you have put the display on the end of a Thunderbolt chain. The display that works on both TB and DVI macs is the the DVI one.

    It is extremely likely though that future Mac Pros will come with Graphic cards with mainstream connectors (i.e., not Thunderbolt). That isn't even "backward" compatible ... that's it is the same compatible.

    PCI-e graphics cards with Thunderbolt connectors are extremely unlikely to appear any time soon if ever.

    No. It only works with a Thunderbolt port.

    thunderbolt sends data as if it were on a pci-e port
    dvi sends data as if it were connected to a video card.

    So..fundamentally incompatable
