I have a LCD FullHD Bravia (Sony) TV, which supports 1080p and 4 hdmi ports. Now, I wanted to connect the TV with my PC (which has 1 hadmi port) using an hdmi cable. The problem is that the image doesnt appear on the TV. If I use a VGA cable (for normal PC monitors), it displays just fine but I get no sound. How can I make my PC appear in the TV screen (as a monitor replacement) with the HDMI connection?
