MDP does not play a role, and you don't need Target Display mode either, but there is no reason that you could not utilize that function if allowed.īlack Magic Designs makes the Intensity Extreme video capture device that uses Intel's TB chip. The TB protocol supports HDMI just fine, if you have Intel's chip, and once the HDMI signal is being passed via TB, other TB devices have no problem accepting the signal. Your a,b,c points sound nice, but those limitations are simply licensing issues. Plenty of people would pay for such an adaptor, and Kanex has already stated that they wish to make such a device as soon as Intel will allow them to utilize their TB chip. It is not an issue of cost as you suggest, only access. The only fundamental law of economics at play is Intel's tight control over the TB chip. There is an except only when plug in a DisplayPort (DP) device and a special 'pass thru'/'backwards' mode is enabled when now (with DP device ) at the end of a Thunderbolt daisy chain. Thunderbolt devices primarily just talk to other Thunderbolt devices. In short, you need a Mac clone (at least from the Target TB mode perspective) hardware. need new non Apple host to implement Apple's non standard Target TB mode protocol. input the DisplayPort signal into a host mode Thunderbolt controller ( meaning you need a CPU and pass TB host mode certification ).Ĭ.

( If go look not going to find many, if any, of these on open market )ī. There are 3 major conversations that need to take place.Ī. Theoretically it is possible but would need much more than an adapter and much more of a contraption. If one of the ways is 'backward' compatible then the other is 'forward' compatible.

Not that the format needs to be converted.

Not 'backwards' compatible means not working. If is not backwards compatible then adapters are not going to work.
