The DVI-D to HDMI adaptor 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 25pin 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. Gold flashed contacts Black plastic housing
