Cannot get anything on my Insignia 50" plasma tv when I try to get an HDMI signal from my ASUS X75A notebook HDMI output.Cable is good, tv has worked using it with dvd's but I want to view NETFLIX from the notebook on my tv. Tried HDMI 1 and HDMI 2 ports on the tv, only one output HDMI port on the notebook. NO audio or video. Any help would be appreciated.ASUS
