Please note: this product can only be used to connect a DVI source to two HDMI displays. It does not allow two HDMI sources to be connected to a single DVI display. This splitter cable allows two HDMI displays to be connected to a computer's single DVI port. It's a passive cable which simply splits a single DVI signal into two without any amplification or signal regeneration, making it an ideal, cost effective solution for shorter installations.
