I have a new Dell laptop, Intel i3 Core series, it has an HDMI port on it. I also have a Zenith LCD HDTV. I am trying to connect my laptop to my tv so I can watch high def movies from netflix on my tv. My tv doesn't have an HDMI port, but it has like 50 other ports. One of those ports is a DVI port. I found a cable with one HDMI male end and one DVI male end, but the sales rep informed me it will not transfer the sound. Any suggestions?
