The DVI-D to HDMI adapter passes DVI-D signals through to the compatible pins in the HDMI spec for use with HDMI equipment. Please note while this uses the DVI-D 24+1 (25 pin) dual link connector this is single link as HDMI is 19pin with a resolution of 1920x1080. DVI-D does not carry audio so the HDMI ouput will not have audio either. The DVI connector is compatible with DVI-D DVI-I and DVI-A connectors but will only pass single link DVI digital signals. Can be used in either direction. DVI-D 24+1 pin male to HDMI 19 pin female Gold flashed contacts Black moulded connectors Length: 15cm
