Do you have a link to this "slimport converter"?
I cant imagine a thing not costing less then just buying an actual slimport/mydp adapter.
It's the equivilent of a ethernet to sata adapter, there would need to be active parts to convert the stream from one to the other, they're completely unrelated.
There's no way it's just a passive thing, slimport/my and mhl use microusb as the connector, but that's about the only thing they have in common.
