I have a laptop that has hdmi output, I have linked to the television and see the image but no sound, anyone familiar if you require to form anything on my computer or on television. When I plug in the cable to my LCD the picture is "too large". That is escaping the top, down, left and right a some inches. In addition, the picture flickers still when playing a HD films (on the Acer screen is all right). That is, one looks a line from top to down, walk by the image.
