You are asking generic questions that we, EmuELEC have no 100% answer to, we are not hardware providers, we provide software, we also do not have every TV box in the market so we cannot test them all. Since this is not an EmuELEC related question (this is more of a will X HW work with EmuELEC), so the answer was complete as you should contact the manufacturer/seller as they will be the ones that can answer your questions the way you want.
