I cant hear the dialogue clearly. Why is there so much background noise?
As with loudness, this is often found to be highly subjective, and can vary from one individual to another. It is often related to an individuals hearing abilities, which can change with age. The effect can also vary according to the type of television set, whether stereo, mono, surround sound etc. Make a note of the programme and contact the broadcaster and preferably direct your comment to the programmes producer. Some programmes have black bands at the top and bottom of my screen. Why is this? Today, many programmes are either produced in a widescreen format with an aspect ratio of 16:9, or are films produced in widescreen for the cinema. They are transmitted in widescreen on the digital service. In order to show more of the width of the scene as the director intended, small black bands are placed at the top and bottom of conventional analogue 4:3 aspect ratio screens. Digital widescreen sets do not show these bands, and most widescreen TVs allow the viewer to zoom into the picture.
