Described are methods, devices, and systems for optimizing presentation of an image-bearing signal on a display device equipped with at least one adjustable picture control variable. The methods utilize, and the devices include, a picture control setting generator for determining different picture control settings, and an on-screen display generator for producing an on-screen display including multiple image cells (e.g., a mosaic). Each cell displays the same received image-bearing signal tuned according to a respective one of the different picture control settings. An end user selects among the different cells, choosing a cell that provides a preferred picture quality. In some embodiments, the picture control setting generator determines new picture control settings in response to the selected cell. Again, the on-screen display generator produces an on-screen display including multiple cells according to the new picture control settings, with the end user selecting one of the cells providing a preferred picture quality. |
