A mosaic of monitor units (201, 202, etc.) contained in a single covering (30) provide higher-resolution monitor displays proportional to the number of monitor units contained in the monitor casement. The extension of the flat viewing surface of the monitor in one or more directions accomodates a touch screen function both over the monitor surface and in the area surrounding it with one transparent layer between both the electronic image and marginal fixed markings. The touch response surface reduces parallax factors. A receiver and signal processor (5) which outputs dual signals, the first defining the image in a Standard Broadcast mode and the second providing selected sharpness where detail is required. The method of transmitting only changes in the high-resolution areas cuts data transmission and recorded data levels.
