Hi. I'm trying to connect my laptop to a samsung LCD tv. I have a VGA and audio cable. When connected the TV is picking up something on the pc stereo source (as it doesn't display the no signal icon) but it just shows a black screen. When the graphics output is changed from notebook to monitor on the laptop the tv displays a not supported icon, I'm guessing thats because it isn't a monitor. The TV clearly supports a computer input as there is a VGA port on the back which says PC in above it. Do I need to change any settings on the laptop to set it up?
