I was trying to hook up my Sony tablet PC with my TV but I was not able to do so. I have got a HDMI cable and I was connecting it through HDMI port of my TV to Sony tablet. But the only message I am getting on TV screen is no external device found. I had also changed the setting of my Sony tablet PC but I have not got any success on this. SO I want to ask this from you people, how I can connect my Sony tablet PC with my TV?
