I have my lap top connected with an HDMI cord to my Samsung tv to watch netflix. The only problem is I can't see the movie but cam hear it. I still see the desktop on the tv but there are no icons. If I turn netflix off I only see the desktop with no icons on the tv but when I look at the computer I see the icons. If I move my mouse to the right it will go off my computer desktop onto the tv. If I move the mouse all the way to the left it will go off the tv and back onto my computer. How do I get my computer and tv to sync up together?
