i was wondering if the image on the large screen would be full. that might be a function of your perticular video card also or when your using the wall screen you might have to go into your display options on the laptop and change your screen resolution to fill it out.....just the same as if you get a larger monitor for your laptop, you have to go into the display setting and change it to get it to look right. anyhow i do have an s-video output on my current video card and an input on the LCD so i'll see what it looks like before i go spend big bucks on a better video card.
